Deformation-resistant frame for seats of motor vehicles
First Claim
1. A seat for use with a safety belt, particularly in motor vehicles, comprising a frame including a base and a back rest, said back rest including two spaced-apart lateral frame members having first portions adjacent and second portions remote from the base, and said back rest further including a connector between said lateral frame members;
- and means for coupling the belt to said frame, including a first coupling element provided on one of said frame members and spaced apart from said base and a second coupling element in the region of said base and remote from the first portion of said one frame member so that, when the belt is in use and extends between said coupling elements, it applies to said one frame member a deforming force acting in the direction in which the belt extends between said coupling elements without the application of such deforming force to the other of said frame members, said one frame member having a non-circular cross-sectional outline with an axis of maximum resistance to said deforming force, said one frame member being disposed in a plane which is inclined with reference to a plane halving said seat and extending between said frame members, the belt between said coupling elements being disposed in or close to the plane of said one frame member.

Abstract
The frame of the seat in a motor vehicle has a base for the cushion which carries the weight of the occupant and a back rest which carries the cushion for the back of the occupant. The back rest has two upwardly extending parallel frame members and a connector between the upper ends of the frame members. The upper end of one frame member carries a takeup reel for the safety belt whose latch plate can be inserted into a buckle adjacent the lower end of the other frame member. When the belt is applied and is tensioned, such as in the event of an accident, it applies to the one frame member a force acting diagonally of the back rest and tending to bend the one frame member forwardly and toward the other side of the seat. The cross-sectional outline of the one frame member and the orientation of such cross-sectional outline are selected in such a way that the one frame member offers maximum resistance to deformation by the belt in the direction in which the belt acts thereon in the event of an accident. This renders it possible to reduce the wall thickness of the one frame member and to make such frame member of simple C-shaped, U-shaped or Z-shaped profiled stock.
