Safety device for a vehicle seat which is fixed inside a vehicle including
lateral guides. The safety device consists of at least one safety rail
fixed in the vehicle, in the region between the guides, and comprises
associated securing mechanisms which are connected to the vehicle seat,
and co-operate with the safety rail in a non-contact manner for regular
loads applied to the seat, and in the event of irregular, especially
accident-related deformations and/or movements in the region of the
vehicle seat, engage with the safety rail in such a way that they block
further deformation/displacements. The securing mechanisms and the safety
rail are embodied in such a way that, during the engagement, reaction
forces which act in the direction of axes (X, Y, Z) of a standard vehicle
co-ordinates system are applied in a distributed manner to at least two
different engagement regions of the safety rail.
