Abstract: In a vehicle occupant restraint system provided in association with a vehicle seat for preventing a vehicle occupant from slipping forward under a seat belt in an impact situation such as a vehicle crash, a pair of casings are provided on either side of the seat frame, and pivotally support a pair of arms across which a cross member extends A power unit pivotally incorporated in at east one of the casings raises the arms and cross member in an impact situation. The casing is formed by a main member having a vertical section and a pair of Ranges extending from upper and lower ends of the vertical section, and a lid member attached to the free ends of the flanges. The hollow structure of the casing provides a high level of mechanical strength, and the two piece structure of the casing allows the assembly work to be performed in a simple manner because the components can be installed from sideways one after another in a relatively simple manner.

Abstract: In a vehicle occupant restraint system provided in association with a vehicle seat for preventing a vehicle occupant from slipping forward under a seat belt in an impact situation such as a vehicle crash, a pair of support members are provided on either side of the seat frame, and pivotally support a pair of arms across which a cross member extends. The cross member comprises an energy absorbing structure adapted to undergo a controlled deformation under a load occurring as the front part of the seat bottom is raised. The energy absorbing structure may consist of a relatively deformable member wrapped around the cross member or a feature for controlling a mode of deformation of the cross member. When the cross member consists of a pipe member, the energy absorbing structure may comprise a relatively deformable member filled inside the pipe member or perforations formed in the pipe member.
