Detailed description of the invention

Present invention relates generally to a kind of constructive elements 10 as shown in figures 1-5 or plate. Constructive elements 10 is formed by the stamped metal of single sheet material generally, and it retains datum plane 18 and forms the pattern 14 of projection in whole backrest surface. Protruding pattern 14 can include the height of the multiple levels relative to datum plane 18. Constructive elements 10 also includes top cross member 20 and sidepiece cross member 18, and described top cross member 20 includes head rest localizer 16, and described sidepiece cross member 18 extends around the remainder of periphery.

The product that the pattern forming protruding pattern 14 illustrated in the accompanying drawings allows constructive elements 10 to be formed as low cost, little quality. More particularly, constructive elements 10 may conform to multiple current seat standard, such as FMVSS202A, ECE17 goods residual (CargoRetention) and other structural requisite. The standard steel of the single sheet material of 1008 or 340XF steel of available such as relative thin ratio (specifically 0.4mm to 0.6mm) realizes all these. By removing support, external member and the use standard steel of thinner ratio for normal, present invention reduces material cost and alleviate seat-weight. The weight saving of seat is even more important in the gross weight alleviating vehicle, therefore improves the fuel economy of vehicle. It addition, by using integral design, reduce manufacturing cost. More particularly, by optimizing geometry, the design of protruding pattern 14 reduces cost and quality, thus allowing to use the steel thinner than the steel of standard thickness.

As Figure 1-4, if constructive elements accounts for 60% (being specifically shown in Fig. 1 and Fig. 3) of seat portion or accounts for 40% (being specifically shown in Fig. 2 and Fig. 4) of seat portion, then it has different patterns. It should be noted that the pattern of 60% can be applied to 50% and the bigger seat that account for back seat, and the pattern of 40% is applicable to the seat of account for whole back seat 50% or less, the seat namely split.

First the similar features of the constructive elements of the pattern of 60% and 40% will be described. Constructive elements 10 is stamped have the protruding pattern 14 extended from datum plane 18. After being stamped, constructive elements has the neighboring 30 formed by reference edge 32, inward flange 34, outward flange 36 and top edge 38. Reference edge 32, inward flange 34 and top edge 38 are substantially straight, but some can be occurred to change. Outward flange 36 has lower straight edge 40, the outward flange 42 bent and upper outside edge 44. The size of outward flange 36, shape and structure can change according to vehicle, and root is it is contemplated that in many cases, outward flange 36 will stretch out thus having the outward flange 42 of bending, but in some constructions, outward flange 36 will be straight, thus not there is the outward flange 42 of bending.

Near reference edge 32, adhering zone 48 may be structured to have multiple hole, and in certain embodiments, use extra hinge plate 50 that constructive elements 10 is connected to base seat portion or vehicle, and therefore seat portion is connected to base seat portion or vehicle. The size of this adhering zone 48, shape and structure can be different according to the expectation function of the type of vehicle and seat.

Constructive elements 10 each includes extending around mode and neighboring rib 52 substantially adjacent to neighboring 30. It should be noted that top cross member 20 is arranged between neighboring rib 52 and top edge 38. Neighboring rib 52 generally includes benchmark peripheral part 54, inner rim part 60, outer peripheral portion 62 and upper periphery part 70. Benchmark peripheral part 54 generally includes the central component 55 substantially alignd with reference edge 32. Benchmark peripheral part 54 also generally includes outer reference angle part 56 and interior reference angle part 58. Interior reference angle part 58 and the outer angled layout of reference angle part 56 think that the hinge plate 50 being arranged in lower limb adhering zone 48 provides space. The change of the size of benchmark peripheral part 54, shape, configuration and angle is contemplated by.

It should be noted that compared with inner rim part 60 and outer peripheral portion 62, upper periphery part is slightly concave or closer to datum plane. Upper periphery part 70 is generally generally across the major part extension of the width of the constructive elements near top cross member 20. Owing to upper periphery part 70 has the height of reduction relative to the remainder of neighboring rib 52, the extra rib component 72 extending and being approximately perpendicular to top cross member 20 and upper periphery part 70 from top cross member therefore can be increased. For the constructive elements of 40%, at least one this ribs component 72 strides across the rib that upper periphery part 70 extends to projection from top cross member 20 between head rest hole 68, but it may also extend into datum plane 18 in certain embodiments.

As shown in Figure 1 and Figure 3, for the part of 60%, including such ribs component 72, at least one of which ribs component 72 is arranged on head rest hole 16 and external head by between another ribs component 72 beyond hole 16, and extends at least two ribs component 72 of datum plane 18 from top cross member 20 and be arranged to the every side being located substantially on latch member. As shown in Figure 2 and Figure 4, on both components of 40% and 60%, extra ribs component 72 is arranged near latch member. Due to the size of the constructive elements around latch member, shape and configuration, the size being arranged to the ribs component 72 near latch member substantially reduces. Although can from these rib components 72 of steel backing face punching press, but in certain embodiments, can cross over upper periphery part 70 from top cross member to weld ribs component.

Outer peripheral portion 62 extends from benchmark peripheral part 54 generally, and specifically upwardly extends from outer reference angle part 56 towards top cross member 20. Outer peripheral portion 62 generally includes lower straight part 64, described lower straight part 64 upwardly extends to connect bandy part 66, and extend in transition portion 68, described transition portion 68 makes outer peripheral portion 62 extend virtually in top cross member 20, and does not reduce the height of upper periphery part 70. Upper periphery part 70 extends to connect with transition portion 68. The actual size of outer peripheral portion 62, shape and configuration alterable are to mate with the size of the vehicle being wherein provided with described constructive elements, shape and configuration.

Now, it has been described that constructive elements 10 has essentially similar feature, wherein in the constructive elements 10 of the constructive elements 10 ' of 60% and 40% " between only exist little change. The constructive elements 10 ' of 60% and the thereon ribs that by neighboring rib 52 surrounded or bossing 14 be will now be described, and the constructive elements 10 surrounded by neighboring rib 40% will be described later on below " on bossing 14. The constructive elements 10 ' of 60% includes triangular fin part 80, and it is about medially formed between inner rim part 60 and lower straight part 64. Triangular fin part 80 generally includes lower leg 84 and interior leg 86 and outer leg 88, and described lower leg 84 substantially aligns with benchmark peripheral part 54, and interior leg 86 and outer leg 88 extend to summit 82 from lower leg 84. As it is shown on figure 3, substantially align with latch member in summit 82. Summit rib 90 extends upwardly to upper periphery part 70 from summit 82, and latch member is arranged on summit rib 90. Triangular fin part 80 is shown generally as equilateral triangle, but can carry out some and change. Constructive elements 10 ' also includes connection rib, and described connection rib extends from cross point on first time summit 83 of lower leg 84 and interior leg 86 and lower leg 84 and outer leg 88 in the cross point on second time summit 85. These connection ribs 92 extend to the cross point between outer reference angle part 56 and outer peripheral portion 62 and the cross point between interior reference angle part 58 and inner rim part 60 from triangular fin part 80. Pair of cross rib, specifically the first diagonal ribs 96 and the second diagonal ribs 98, each substantially extends towards the interior leg 86 of triangular fin part 80 and outer leg 88 from the upper outer turning of the upper interior turning of constructive elements and constructive elements respectively. More particularly, one of diagonal ribs 96,98 substantially extends from the cross point of the upper periphery part 70 of neighboring rib 52 and inner rim part 60, and another of diagonal ribs 96,98 extends about outer leg 88 from the cross point of upper periphery part 70 and transition portion 68. More particularly, the arrangement mode of each diagonal ribs is as follows: they substantially form x shape pattern, but they are also indefinite intersected with each other, if diagonal ribs 100 extends, then they will form each x shape pattern intersected of wherein opposite end and outer reference angle part 56 and interior reference angle part 58. It should be noted that, the interior leg 86 of triangular fin part 80 (includes one of connection rib 92 of extending towards interior reference angle part 58 and the outer peripheral portion 62 being positioned on one of diagonal ribs 100) and generally forms second triangular shaped 102, and described second triangular shaped 102 is triangular shaped similar to formed on datum plane by triangular fin 80 first. Similarly, one of summit rib 92, the diagonal ribs 100 that extends from the interior leg 86 of triangular fin part 80 and upper periphery part 70 form interior triangular shape 104 on datum plane 18. Owing to including the bandy part 60 of the outer peripheral portion 62 of transition portion 68, increasing by two extra ribs 110, they extend to the diagonal ribs extended towards transition portion 68 from the outer leg 88 of triangular fin part 80 especially from one of diagonal ribs 100. One of extra ribs extends between the cross point of diagonal ribs and the lower straight part 64 of bandy part 66 and outer peripheral portion 62, and the overall cross point extending to summit rib 90 and upper periphery part 70 from diagonal ribs 100 of ribs 110 that another root is extra.The rear extra ribs 110 described generally forms and is referred to herein as the triangular shaped of outer dead centre triangular shaped 106, and described triangle utilizes described extra ribs, diagonal ribs and summit rib 90 as its neighboring.

The constructive elements 10 of 40% be will now be described " the pattern 14 of structural projection. As it has been described above, the constructive elements 10 of 40% " generally include outer peripheral portion 62, compared with the constructive elements 10 ' of 60%, outer peripheral portion 62 has a change. Outside on peripheral rib 52, specifically, in inner rim part 60, breech lock installation region 120 recessed, that expand is set, and the breech lock in the constructive elements 10 ' of 60% is disposed on summit rib 90. But, compared with inner rim part 60, breech lock installation region 120 will have the relatively low height relative to datum plane 18, but compared with upper periphery part 70, breech lock installation region 120 still has the bigger height relative to datum plane 18. Main crossings rib 130 extends from the cross point of the main portion 124 of interior part 60 with breech lock installation region 120, and it extends downwardly and outwardly and the cross point of outer reference angle part 56. Many vertical rib 132 extend from main crossings rib 130, and vertical rib 132 each limits recessed portion 134 between which, and specifically, described many vertical rib 132 are the first vertical rib 140,142,146 and 148 respectively. At least one root that vertical rib 132 generally includes at least one root that at least one root with upper periphery partial intersection and outer peripheral portion intersect and inner rim partial intersection and at least one root intersected with benchmark peripheral part 54 (specifically, with interior reference angle part 58). As shown in Figure 2 and Figure 4, the extra vertical rib in the cross point (specifically, the cross point between transition portion 68 and upper periphery part 70) extending to generally peripheral part 70 and outer peripheral portion 62 from main crossings rib 130 is set. Therefore, three vertical rib 132 outwardly and upwardly can extend from diagonal ribs 130, and two vertical rib 132 extend downwardly and inwardly from diagonal ribs.

Additionally, the design of the protruding pattern 14 combined to top cross member 20 is by being directly integrated into and reduce cost and quality by head rest localizer 16 and relevant supporting member feature on plate 10, thus eliminating the additional step of the welding support increasing cost and weight. Constructive elements 10 can allow various head rest position, and the head rest including outer and middle designs. The seat of other ratio different from the 60%/40% of diagram segmentation configuration is can be used for by the protruding pattern 14 shown in accompanying drawing being carried out the constructive elements 10 of little change. Protruding pattern shown in Fig. 1 and Fig. 3 is especially preferred for use in the seat of 60% segmentation configuration. Protruding pattern 14 in Fig. 2 and Fig. 4 is especially preferred for use in the seat of 40% segmentation configuration. Certainly, it is illustrated that the version of protruding pattern can change along with the height of armchair structure component 10 or change width. Pattern can when little amendment for the back seat of the back seat of 50%/50% segmentation or 100%.

Along with the height of vehicle structure component 10 or width increase, the width of generally protruding pattern 14 and highly proportionally increasing. By increasing width and the height of the pattern 14 of projection, keep structural integrity.
