Abstract:
A back support mechanism for supporting the back of a seat in a motor vehicle, the seat back support mechanism comprising: at least one first component adapted to be connected to one of the squab of the seat and a frame supporting the squab of the seat; at least one further component adapted to be connected to the back of the seat; a connection between the components including means to permit the further component to move with a first pivotal action relative to the first component and with at second pivotal action relative to the first component, said means comprising a linkage including two pivot link elements, the pivot link elements each being mounted to effect a pivotal movement relative to said at least one first component, wherein said further component is one of directly supported and indirectly supported by the pivot link elements, the pivot link elements pivoting said further component to effect an initial rearward pivotal movement which constitutes said first pivotal action before effecting said second pivotal action, and said connection including a deformable element which resists said second pivotal action, said deformable element being adapted to deform to permit the second pivotal action when subjected to a force in excess of a predetermined threshold.
