Abstract
Abstract A safety belt arrangement for a vehicle seat to automatically position the seat belt around the seat occupant as soon as he is seated. One or several driven elongated carriers draw the seat belt into its interlocking position, are released for return to their starting positions as the latch mechanism is closed and are automatically reconnected to the component latch parts when the latch mechanism is unlocked. The operation sequence is activated by a switch in the seat cushion responding to pressure in excess of a given value. Structural details permit mounting the arrangement after car assembly and keep the device and the seat belt straps out of sight when not in use.
