Abstract

Described is an apparatus for adjusting the inclination of a seat squab (12) of a vehicle seat (10), wherein the device (18) has a rocker (20) with an upper and a lower rocker element (22, 24) which are pivotably movably connected together by lateral bearing bushes (36). Fixed to the upper rocker element (22) is a toothed bridge (38) with mutually oppositely disposed bridge tooth arrangements (40) which are concentric with respect to the bearing bushes (36). Provided between the two bridge tooth arrangements (40) of the toothed bridge (38) are two toothed sliders (64) with slider tooth arrangements (66). Provided between the two toothed sliders (64) is a locking member (48) rotatable about a rotary axis (26) extending through the bearing bushes (36). The two toothed sliders (64) are linearly movably guided on the lower rocker element (24) between a locking position and a release and adjusting position. Provided between the rotary axis (26) and the lower rocker element (24) is a prestressed spring element (74) which urges the two toothed sliders (64) self-lockingly into the locking position.
