DE1120291B - Closed, four-door car body for motor vehicles - Google Patents

Description

The invention relates to a closed, four-door car body for motor vehicles with three thin posts on each side supporting a solid metal roof, the middle of which is the dividing line between the front and rear doors and of which the other two are above the belt or hip line of the car body Follow the dividing line between the panes of glass or run close to them.

In known car bodies of this type, the three posts have continuously the same circular cross-section and together with their connecting parts and stiffeners form part of the fixed side walls. This gives the car body a high degree of rigidity, but the potential window area is increased limited if the visibility is restricted accordingly.

In another known car body with an outer skin consisting of elastic molded materials run the posts at a distance inward from the outer skin, being separated from the Outer skin attached to the car floor or to the rear wheel arch, connected to the roof racks or consist of one piece with these and elastic connections with the outer skin at individual points exhibit. Apart from the fact that this training is only suitable for two-door car bodies is, you can not achieve the rigidity of the metal car bodies with it. Besides, will also the limitation of the possible window area is not removed, since the windows are in the load-bearing structure included and the posts are made stronger due to the lack of rigidity of the outer skin have to.

In the case of a car body with a transverse rib, it is also known to convert the transverse rib in a transverse manner To arrange the dividing level of the car body and to use it as a link between the two box parts.

In the case of a car body of the latter type, but without a dividing joint, it is finally known that the To let the transverse frame run entirely or partially outside the box or in the area of the same.

The aim of the invention is to create a closed, four-door car body of the type described above Art, the window area of which is essentially uninterrupted around the entire body of the car walks around without the visibility of the posts above the belt or hip line are noticeably impaired, and still has sufficient rigidity.

According to the invention, this object is achieved by the combination of the following features:

Closed, four-door car body

David Brynmor Jones, Radlett, Hertfordshire

(Great Britain),
has been named as the inventor

a) that the center post is in a known manner above the hip line inwards in a distance from the doors and below this line flat between the inner door panels are arranged, but are overlapped by the outer door surfaces,

b) that the other two posts in a known manner above the hip line inwards are arranged at a distance from the dividing lines between the panes of glass,

c) that the dividing lines between the panes of glass are made correspondingly narrower and thereby the appearance of the car body above the waist line is closer to an uninterrupted one Glass surface approximates and

d) that each post is circular in cross-section above the hip line in a manner known per se having.

Preferably, the flat lower portion of the center post is designed to provide the hinges for the rear door and the striker for the front door.

The invention provides a stiff car body design with significantly improved visibility created and thereby the mutually contradicting requirements for rigidity and good all-round visibility.

An embodiment of the invention is described and illustrated in detail with reference to the drawing.

Fig. 1 is a schematic view of a four-door closed motor vehicle;

Fig. 2 is a section along the line II-II of Fig. 1;

Fig. 3 is a representation of a portion of Fig. 2 on an enlarged scale, and

FIG. 4 is a section approximately along line IV-IV of FIG. 1.

In the motor vehicle shown in the drawing, the roof 1 is three on each side Steel posts 2, 3 and 4, each about 2 to 3 cm from the side walls of the car body are distant. The center post 3 is vertical and stands exactly in front of the line in which doors 5 and 6 meet. The rear post 4 is inclined and lies just behind the line in which the rear door and one across the width of the car body meet extending rear window 7 abut one another. The front post 2 is also inclined and lies just in front of the line in which the front door 5 and the side edge of a curved, over the whole Car-width reaching windshield 8 abut one another.

All posts 2, 3, 4 are connected, for example by welding, to the roof 1 at the top and to the floor pan or subframe of the vehicle at the bottom. The post 4 is connected at the bottom with the wheel installation. The posts 2 and 4 can have a round cross-section over their entire length. However, their cross-section can also be different. The center post 3 has an upper part 3 A above the hip line 9, which has a round cross-section, and similar to the posts 2 and 4, it is 2 to 3 cm away from the side walls of the car body, which here consist of the doors. The lower part 3 B of the post 3 has a flat cross-section and is arranged between the edges of the doors S and 6. More precisely, the part 3 B is arranged between the inner panels of the doors, but does not extend to their outer door panels. The outer door panels of the doors 5 and 6 overlap the post part 3 B so that it is not visible from the outside when the doors are closed. In Fig. 4, SA means the inner panel of the door 5 and SB its outer panel.

The hinge axes of the doors 5 and 6 lie on their front edges. The door 5 is attached to the draft shield 10. The part 3 B of the post 3 carries the hinges 11 for the rear door 6 and also the closing plate (not shown) for the door lock of the front door.

The frame of the door S above the hip line consists only of a thin metal profile 12, which the vertically sliding window 13 receives and guides as well as the necessary sealing profiles. The rear door 6 consists of a thin metal profile 14 and one above the hip line vertically movable window IS. The frame 12 of the door 5 carries a sealing profile 15 which the Seals the door edge against the edge of the windshield. To seal the gap between the Doors 5 and 6, a sealing strip 16 with a wide lip 17 is attached to each of the two doors. As can be seen from Fig. 3, the lips of these sealing profiles overlap and seal regardless of which door is closed first.

The weight of the roof 1 and its tensions are taken up by the posts 2, 3 and 4, but these are not visible from the outside, so that one has the impression of an almost uninterrupted glass surface around the top of the car body.
