Abstract

A vehicle seat arrangement has a vehicle seat for attaching to a vehicle structure of a vehicle, in particular a motor vehicle, with a lower seat part having a seat structure and with a seat back. The lower seat part is mounted or can be mounted in a longitudinally displaceable manner on the vehicle structure by a seat console, wherein at least the seat back is adjustable from a sitting position into a resting or lying position, and wherein between the lower seat part and the vehicle structure an energy absorption device is provided. In the event of a collision of the vehicle with an obstacle, the energy absorption device permits a braked relative movement along a braking path between the vehicle seat, which persists in a forwards movement due to inertia, and the vehicle structure, which is braked due to the collision. In the normal state, the vehicle seat is locked relative to the vehicle structure by a locking device and the locking is released in the event of a collision. The locking device is designed such that the locking is released and the longitudinal displaceability of the vehicle seat is enabled before the mass-induced forces of inertia of the body of a person lying on th…
