When disassembling after a gas being supplied into a tube member, the gas in the tube member is discharged before the tube member and a moving member become separable. In a webbing take-up device, a cover plate cannot be removed from a frame and thereafter a cylinder and a piston inside the cylinder cannot be separated before covering of a fixing screw with a covering section of a plate being released by removing a screw from an exhaust port of the cylinder and by removing the plate from the cylinder. Thus, after a high-pressure gas being supplied into the cylinder, the high-pressure gas inside the cylinder can surely be discharged by removing the plate from the cylinder and the exhaust port is opened by the screw before the cylinder and the piston being separated.

A seat belt device includes a belt reel around which webbing is wound, a winding spring that rotationally biases the belt reel in a winding direction, a motor that is configured to transmit a driving force to the belt reel, a clutch that is interposed between the motor and the belt reel, and which performs connection/disconnection of the motor and the belt reel, a webbing speed detection unit that detects the winding speed of the webbing, a fastened/released state detection unit that detects a fastened state and a released state of the webbing, a basic winding control unit that drives the motor in the winding direction in a rotating manner and puts the clutch into a connected state, and a speed increase correction unit that increases the speed of the motor with respect to the speed of the motor obtained by the control of the basic winding control unit.

A backward accident protection (BAP) system includes a video camera attached to the rear windshield of a vehicle. A microcomputer analyzes the camera image to assess the risk of a rear impacts. Upon detection of a potential rear impact, the BAP system initiates actions to reduce the severity of the potential rear impact.

A switching mechanism (100) in a force limiter mechanism of a seat belt retractor including: a locking mechanism including a locking element (68) that locks a torque tube (64) with respect to a spindle (61) so that the torque tube (64) rotates together with the spindle (61) and a spindle ring (70); a switch ring (120) rotatable to unlock the locking mechanism; and a switch housing (101) that stores the switch ring (120), a switch piston (115) adapted to activate the switch ring (120). A switching gas generator (116) generates gas for pushing out the switch piston (115) upon activation of the switching mechanism. The switch housing (101) of the switching mechanism (100) has a protrusion (110) that protrudes in an incoming direction of an operated part (122) at an abutment part hit by the switch ring (120) rotated by the switch piston (115) to control movement of the switch ring.

Provided are a pretensioner, a retractor, and a seat belt device that can achieve weight reduction of a device by improving slidability of a power transmission member used for the pretensioner. A pretensioner includes a drive wheel for rotating the spool, and a power transmission unit for transmitting power to the drive wheel in an emergency. The power transmission unit includes a power transmission member for rotating the drive wheel, a pipe that contains the power transmission member, a gas generator for supplying a working gas into the pipe, and a housing that defines a passage for the power transmission member on an outer periphery of the drive wheel. The housing has a sliding member that is disposed at an outlet part of the pipe and that reduces frictional force between the housing and the power transmission member.

A belt reel (14) for a belt retractor (10) has a rotational axis (R) and a reel body (16) that is provided as a reel for a webbing (24) and has a first axial circumferential circle (34). The reel body (16) further includes a radial constriction (32) having a second axial circumferential circle (36), wherein the constriction (32) is arranged centrally on the reel body (16) in the axial direction (A) and wherein the circumference of the second axial circumferential circle (36) amounts to a maximum of 95% of the circumference of the first axial circumferential circle (34). Moreover, a belt retractor (10) comprising such belt reel (14) is described.

A pet restraint system for a vehicle is provided. The pet restraint system includes a leash configured to connect to a restraint device on a pet, a wearable device comprising one of a collar and a harness configured to be worn on the pet and connected to the leash, a retractor device coupled to the leash and configured to be secured to a support structure on the vehicle, a sensor for detecting an expected condition of the vehicle, and a controller for controlling the retractor to retract or lock the leash based on the determined expected condition of the vehicle.
