Abstract: A ratchet-type adjustment device for the ratcheting displacement of an adjustment body with respect to a fixed base element having an oblong actuating element, where the actuating element can be displaced along linear toothed portions, which are fitted to the adjustment body on either side of the actuating element, and latched into the first linear toothed portion, acting as driving toothed portion, by first ratchet elements, the adjustment device furthermore comprising at least two second ratchet elements mounted pivotably on the fixed base element, which ratchet elements can be latched into the second linear toothed portion, acting as blocking and braking toothed portion, to block a displacement movement of the adjustment body with respect to the fixed base element.

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.

Abstract: A vehicle seat comprises a seat squab supported on a base structure, and a spring arrangement for weight adjustment, the spring arrangement being connected to a weight adjustment actuating device. Associated with the actuating device is a level indicator device for indicating adjustment of the seat squab to the seat squab level which optimally corresponds to the weight of the respective seat occupant, in relation to the spring travel of the seat squab. The level indicator device and the actuating device are provided at least substantially centrally at the front edge of the seat squab for optimum actuability and adjustability.

Abstract: In an arrangement for displacement of a displacement member along a stationary base by means of a reciprocatable elongate actuating member, the displacement member has at least one linear tooth arrangement. Two axially spaced ratchet members are pivotably mounted on the actuating member at at least one longitudinal edge thereof. The ratchet members diverge away from each other and have ratchet teeth which are operable to engage with the linear tooth arrangement. The ratchet members are urged towards the linear tooth arrangement by springs. Operatively disposed between the at least one linear tooth arrangement and the actuating member, for disengagement of the corresponding ratchet member out of the linear tooth arrangement, is a disengagement member determining the linear stepping advance movement performed by the displacement member.
