ABSTRACT:
A seat back support mechanism supports the back of a seat in a motor vehicle. One component of the mechanism (15) is effectively connected to the seat of the motor vehicle and another component (32) is connected to the back (44) of the motor vehicle optionally by means of a recliner mechanism. The support mechanism comprises a connection between the components. The connection comprises two pivot links (27,33). One pivot link (33) is of arcuate form with a central “V” notch so that when the back of the seat is subjected to a predetermined force, the back of the seat is permitted about a pivot axis (30) while the arcuate pivot link (33) is deformed, thus absorbing energy.
