Abstract

An automobile vehicle seat safety belt has a security release device including a member releasably connected to an attachment on an end of the belt, the member being mounted in a fixed casing for spring opposed movement in response to traction in the belt when the member is moved by a traction in the belt exceeding a given value, e.g. upon an impact of the vehicle, contacts carried by the member actuate breaking of the vehicle'"'"'s ignition circuit and, after a given delay, release of the attachment from the member whereby the occupant can free himself or be freed from the belt without having to open the conventional buckle.

b. a casing fixed in the vehicle, said casing including means defining an opening removably receiving said attachment piece and said pivotally movable catch;

c. a member movably mounted in said casing;

d. spring means opposing said movement of the member;

e. means for normally holding said catch in a fixed position, relative to said member, to lock said attachment piece in said casing; and

means for releasing said holding means in response to movement of said member by an amount corresponding to a given traction in the belt and after a given delay whereby said catch may pivot on said attachment piece for withdrawal thereof through said opening.

2. A device according to claim 1, said holding means comprising an electromagnetic bolt and said releasing means comprising a relay controlling said bolt and a switch, actuated by said movement of said member to control said relay.

3. A device according to claim 1, in which said security device include a switch for breaking an ignition circuit of the vehicle in response to said movement of said member.
