Abstract: A device for simulating a collision of a motor vehicle by a laterally hitting impactor. The device comprises a seat carriage (3) which can be displaced in the transversal direction of the vehicle and on which a seat (5) is mounted, a lateral part carriage (10) on which a lateral part (13) of a motor vehicle body is mounted, and the impactor (20) that acts upon the lateral part (13) and is provided with an acceleration mechanism (21). The seat carriage (3) and the lateral part carriage (10) can be displaced independently of each other. In order to create a testing device which dispenses with the need for expensive and time-consuming preliminary tests to determine the settings for the tests, the impactor (20) is equipped with an acceleration mechanism (21) which can perform both positively and negatively accelerated movements in a controlled manner while an additional impactor (30) is provided that acts upon the seat carriage (3).

Abstract: In a vehicle seat having a backrest portion and a head support carried on the backrest portion by a connecting device, to reduce whiplash risk by forward displacement of the head support into a more effective head-supporting position, a displacement device is linearly movably carried on the backrest portion of the seat. The displacement device has a sliding guide arrangement on which the head support connecting device is so guided that displacement of the displacement device in the transverse direction of the seat causes displacement of the head support forwardly of the seat. The displacement device is connected for displacement thereof to a pyrotechnic drive element on the backrest portion, with the drive element being activated by a vehicle-specific acceleration sensor.
