ABSTRACT:
A seat belt system for a vehicle including an impact energy absorbing device mounted between a seat belt for restraining an occupant and a seat belt anchor means. The impact energy absorbing device includes a cutter, a member disposed in juxtaposed relation to the cutter and adapted to be sheared by the cutter as the member and the cutter move relative to each other, and a cutter supporting member to which the cutter is securely fixed. When the vehicle collides, the impact energy is absorbed by the shearing of the member by the cutter. The shearing load exerted on the member may vary depending on the tension speed exerted on the seat belt at the time of collision, so that the movement of the occupant caused by the collision can be confined to a substantially constant range at varying collision velocities and a secondary collision of the occupant against an instrument panel or the like can be prevented.
