Title: LUMBAR SUPPORT FOR A SEAT
Abstract:
The invention relates to a lumbar support (100) for a seat (200), which defines a back plane (E), comprising a support device (10) having an upper end (O), which encloses an upper angle of inclination (α) with the back plane (E), and a lower end (U), which encloses a lower angle of inclination (β) with the back plane (E), and forming a vault apex (S), which is 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), which is connected to the upper end (O) or the lower end (U), and which is suited to change the upper angle of inclination (α) or the lower angle of inclination (β) in order to adjust the position of the vault apex (S), and an actuator (30, 35) for adjusting the angle adjuster (20, 25).
