摘要： In a seat belt pretensioner device, comprising a seat belt buckle which is supported in a moveable manner, a power generator for moving the buckle in a direction to increase a tension of the seat belt, and a reverse preventing device for preventing the reversal of the movement of the buckle, the reverse preventing device consists of a ball-type one-way clutch defining a plurality of chambers between an inner race and an outer race, each of said chambers narrowing in a rotational direction and receiving a ball and a spring urging the ball toward a narrower part of the corresponding chamber, and the springs are formed by bending a plurality of projections integrally formed in a peripheral part of a single disk shaped plate member into a wavy form. Thus, the multitude of springs are formed by a single member, and not only the management of component parts is simplified but also the assembly work for the one-way clutch is facilitated even when the one-way clutch is not adapted to be formed as a subassembly.

摘要： In a pretensioner device for automatically increasing a tension of a seat belt in case of a vehicle crash which uses a piston and cylinder arrangement as a power generator, a spring member resiliently urges the piston assembly in the direction of actuation so that any play that may be present in each connecting potion of the path of power transmission can be eliminated. Therefore, collision between component parts at the time of activating the power generator can be prevented, and the loss of energy which could arise from such collision can be avoided. The piston assembly may comprise a piston main body slidably received in the cylinder, and a piston rod having a base end abutting an opposing end of the piston main body and a free end projecting out of the open free end of the cylinder while the cylinder is provided with an inwardly directed radial flange for preventing the piston main body from being projected out of the cylinder. Thus, the piston rod may be kept removed from the assembly during transportation and storage so that an inadvertent activation of the power generator would only cause the movement of the piston main body inside the cylinder, and the handling of the assembly can be therefore simplified.

摘要： Disclosed is a seat belt pretensioner device for moving a moveably supported seat belt buckle in a direction to increase the tension of a seat belt with a power generating device so as to automatically increase the tension of the seat belt in case of an impact situation. such as a vehicle crash. The power generator comprises a bladder-like member that can be pressurized for expansion, and a chamber defined for guiding the direction of the expansion of the bladder-like member. The buckle of the seat belt can be moved in the direction to increase the tension of the seat belt by pushing a member supporting the buckle with the bladder-like member.

摘要： 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.

摘要： 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 least 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 or flanges 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.

摘要： A vehicle safety device (13) includes an actuator (17) which thrusts a hood (11) upward from underside at a point close to a rear end of the hood (11) to raise the same by a specific amount when an obstacle is detected, and a mechanical connector (21) which connects the rear end of the hood (11) to the vehicle body (12), the mechanical connector (21) being structured such that, when the actuator (17) raises the rear end of the hood (11), the mechanical connector (21) extends while swinging about a pivot (P) by which the mechanical connector (21) is joined to the vehicle body (12). The mechanical connector (21) includes a rod (24), and a locking part (26) having a through hole (32a) in which the rod (24) is inserted. The locking part (26) engages with the rod (24) in such a manner that the rod (24) can move in only one direction in which the rod (24) is extracted from the locking part (26), and the rod (24) is disengaged from the locking part (26) when turned about a longitudinal axis.
