Vehicle seats

Claim 1

A vehicle seat comprising a seat base, a backrest and structure supporting the seat base for sliding movement forwardly and rearwardly, the backrest and seat base being coupled together at spaced pivotal connections by a link which is also pivotally coupled to the supporting structure below its said pivotal connections with the backrest and seat base, releasable locking means being provided to maintain said link in a fixed predetermined angular position, whereby, when said locking means is released, folding of the backrest relative to the seat base pivots said link about its pivotal connection with said supporting structure and thereby imparts sliding movement to the seat base, said vehicle seat including second releasable locking means for controlling the angular inclination or said backrest relative to the seat base, said second locking means comprising an elongate member mounted on the seat base, below the pivotal connections between the link and the seat base and backrest, for sliding displacement in its lengthwise direction and a locking element mounted on said seat base and operable to engage said elongate member and being connected to said backrest by coupling means which, when said locking element is inoperable, translates angular movement of the backrest about its pivotal connection with said link into said sliding displacement of the elongate member whereby the backrest can be pivoted to a desired angular setting and held at such setting by rendering said locking element operable.
