Motor vehicle seat has electrically operated seat back inclined forward in event of rear impact crash and braked here by brake device and energy absorber

摘要

the seat back adjuster is driven by an electric motor drive which can be activated in the event of a rear impact crash so that the seat back inclines forward. Following the forward incline movement of the seat back in the event of rear impact a brake device brakes any movement back again. The brake device is formed by an electric motor (4) of the drive device and/or a separate energy absorber (3) which acts between a rigid backrest frame (11) and a rigid seat understructure (16) supported on the vehicle structure
