Description

[Detailed Description of the Invention] "Industrial application field" The present invention relates to a vehicle seat in which a seat back restrained in an upright state is supported by a seat cushion so as to be lifted and released from the restraint and foldable forward. The present invention relates to, for example, those used as center seats for trucks and the like.

"Prior Art" As a conventional vehicle seat, for example, there is one as shown in FIG.

That is, the support bracket 3 is fixed to the rear end of the seat cushion 1, and the connecting bracket 4 positioned inside the support bracket 3 is fixed to the lower end of the seat back 2.
The support bracket 3 is provided with a vertically long hole 5, and a pin 6 loosely fitted in the vertically long hole 5 is fixed to the connecting bracket 4.

When the seat back 2 is lifted when the seat back 2 is folded, the pin 6 moves upward along the vertically elongated hole 5 and the engaging portion (not shown) provided on the connection bracket 4 is disengaged from the support bracket 3 and the seat back 2 is pulled up. The restraint of 2 is released, and the seat back 2 can be moved forward.

[Problems to be Solved by the Invention] However, in such a conventional vehicle seat, the portion where the connecting bracket 4 and the support bracket 3 are connected is visible from the outside, and the connected portion is different from the seat trim member. There is a problem that the appearance quality is impaired by giving such a feeling.

If the connecting bracket 4 is covered with the skin material 2a on the seat back 2 side so that the connected parts cannot be seen from the outside, the support bracket 3 is connected to the outside of the connecting bracket 4, so that the seat back can be folded. In some cases, the outer support bracket may be rubbed and damaged by the outer support bracket 2a. Further, the connection bracket 4 may be positioned outside the support bracket 3, and the cover 2a on the seat back 2 side may be attached to the connection bracket 4. Support bracket 3 when covered
The skin material 2a cannot cover the engaging portion (not shown) on the side of the connecting bracket 4 that engages and disengages with the skin, and the vicinity of the engaging portion can be seen from the outside, impairing the appearance quality.

The present invention has been made in view of such a conventional problem. The connecting portion between the connecting bracket 4 and the supporting bracket 3 is hidden from the outside by a trim member, and the outside of the seat is unified with the same quality, and the appearance quality is improved. It is intended to provide a vehicle seat in which the trim member does not come into contact with the support bracket and is not damaged when the seat back is folded.

[Means for Solving the Problem] The gist of the present invention for achieving such an object is to raise a seat back restrained in an upright state, release the restraint, and use a seat cushion that can be folded forward. In a vehicle seat that is supported, a support bracket is fixed to the rear end of the seat cushion, and a connecting bracket is fixed to the lower end of the seat back so that both brackets can be moved up and down relatively. An engaging portion that engages and disengages with the support bracket is provided on the connecting bracket so as to release the restraint when the seat back is lifted, while movably connecting and restraining the seat back in the upright state. A plate is fixed to the outside of the bracket so as to be continuous with the side surface of the seat back, and the plate and the connecting bracket are connected. As the support bracket is arranged in the gap between, lies a trim member to conceal the connection bracket from outside the vehicle seat, characterized in that coated on the plate.

[Operation] In the upright state, the engaging portion on the connecting bracket side is engaged with the supporting bracket side, and the seat back is restrained to the seat cushion side so that the seat back cannot be tilted forward.

The connecting bracket is hidden from the outside by the plate, and the plate is covered with the trim material, so that the connecting bracket and the plate, which are different from the trim material, cannot be seen from the outside and the appearance is not spoiled.

When the seat back restrained in the upright state is lifted, the connecting bracket and the support bracket relatively move in the vertical direction. Before and after the vertical movement, the engaging portion on the connecting bracket side is disengaged from the supporting bracket side, and the seat back can be tilted forward. At that time, since the trim member covered on the plate side is provided separately from the connecting bracket having the engaging portion, the trim member does not interfere with the support bracket and the trim member is not damaged, so that the seat back can be secured. It can be folded.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1 and FIG. 4, the seat cushion 2 is attached to the vehicle body 10 via mounting brackets 21, 21.
A zero frame 22 is fixed, and support brackets 24, 24 are fixed to the rear end of the frame 22.
On the other hand, connecting brackets 34, 34 are fixedly attached to the lower end of the frame 32 of the seatback 30, and the support bracket 24 and the connecting bracket 34 are connected by a pin 40.

As shown in FIGS. 1 to 3, a vertically long hole 26 is formed in the support bracket 24, and a pin 40 is vertically movably and rotatably fitted in the vertically long hole 26.

A plate 36 is fixed to the frame 32 at a position outside the connecting bracket 34, and a pin 40 is provided between the connecting bracket 34 and the plate 36. The pin 40 is fastened by a bolt 50 penetrating the shaft hole 42 of the pin 40 from the plate 36 side and screwed into a nut 55 on the connecting bracket 34 side.

The pad member 31 of the seatback 30 is extended along the inside of the connecting bracket 34. A gap larger than the plate thickness of the support bracket 24 is provided between the connecting bracket 34 and the plate 36.
Can be relatively moved without interfering with the pad material 31 and the like.

On the outer side surface 37 of the plate 36, the lower extension 3 of the skin material 38 is formed.
9 is extended and is prevented from coming off by the flange 44 of the pin 40 so that the plate 36 cannot be seen from the outside. Due to the downwardly extending portion 39, not only the plate 36 but also the connecting portion between the connecting bracket 34 and the support bracket 24 cannot be seen from the outside. Lower part 39
Is the trim member.

The lower extending portion 39 does not have to be provided integrally with the skin material 38.
The length of the downward extending portion 39 is set so as not to project backward from the lower end portion of the seat back 30 when the seat back 30 shown in FIG. 6 is folded.

A slit 39a is provided at a boundary portion between the surface portion 38a of the skin material 38 and the downwardly extending portion 39, and the slit 39a prevents the skin material 38 from interfering with the support bracket 24 when the seatback 30 is tilted forward. There is.

Hooking pins 28 are planted in the support bracket 24, and the semicircular recess 3 formed in the lower end edge of the connecting bracket 34.
