Abstract
A vehicle seat comprises an inner framework, the inner framework defining a first portion (11, 12, 13, 14) to be received within the squab of the seat and the second portion (15, 16, 17) to be received within the back of the seat. The second portion (15, 16, 17) is mounted on the first portion (11, 12, 13, 14) for rearward pivotal movement about a predetermined pivotal axis (19). Connected between an element (20) which moves in response to movement of the second portion of the framework (15, 16, 17) and the first portion of the framework (11, 12, 13, 14) is an element that provides a mechanical advantage, in the form of a lever arm (27) and a damper in the form of a gas springs (32). The mechanical advantage provided by the lever arm element (27) changes as the second portion of the framework (15, 16, 17) pivots rearwardly about the pivot axis (19). Thus, in a rear impact, an occupant of the seat is given a gradual acceleration.
