Abstract: A lumbar support (100) for a seat (200) defining a back plane (E) comprises a support device (10) having an upper end (O) including an upper angle of inclination (?) with the back plane (E) and a lower end (U) including a lower angle of inclination (?) with the back plane (E) and forming an crown of the curvature (S) located in an adjustable position between the upper end (O) and the lower end (U). The lumbar support (100) further comprises at least one angle adjuster (20, 25) connected to the upper end (O) or the lower end (U) and adapted to vary the upper angle of inclination (?) or the lower angle of inclination (?) in order to adjust the position of the crown of the curvature (S), and an actuator (30, 35) for adjusting the angle adjuster (20, 25).

Abstract: Actuator (100) for an adjustable component, in particular of a motor vehicle, comprising a wire (10) made of a shape memory alloy having a first end portion (11) and a second end portion (12) and extending in an axial direction (A) over a variable length (L); an actuating element (20) movable in the axial direction (A) between a first position (I) and a second position (II); a floating support (30) by which the wire (10) is movably supported in the axial direction (A); a fixed support (33) by which the wire (10) is fixedly disposed in the axial direction (A); at least one abutment (40, 45) connected to the floating support (30) or the fixed support (33) and provided with a through-opening (41, 46) for the wire (10) and a support surface (42, 47) adapted to transmit a force in the radial direction (R); and having at least one elastically deformable connecting element (60, 65) which has a receiving opening (61, 66) for the wire (10), which has a variable diameter (DA1, DA2) and in which the wire (10) is clamped

Abstract: The invention relates to a latching fitting (10), in particular for a seat of a motor vehicle. The latching fitting (10) comprises a base plate (20), a cover plate (30), at least one blocking arm (40, 140) and an actuating plate (50). The cover plate (30) is rotatable relative to the base plate (20) and has an internal toothing (31). The blocking arm (40, 140) is arranged on the base plate (20) and is pivotable between an unlocked position, in which rotation of the cover plate (30) relative to the base plate (20) is possible, and a locked position, in which rotation of the cover plate (30) relative to the base plate (20) is blocked. The actuating plate (50) is rotatable relative to the base plate (20) and shifts the blocking arm (40, 140) between the unlocked position and the locked position. The internal toothing (31) has first blocking teeth (34) which have a vertex (35) and which are formed asymmetrically with respect to a radial axis (A) which runs through the vertex (35).
