To make a rotatable vehicle seat be rotatable in a small space, in a vehicle seat (1) including a seat cushion (7) provided on a floor (2) of a vehicle and a seat back (8) provided on the seat cushion, the seat cushion is provided on the floor so as to be rotatable about a selected one of multiple rotation axes (A) extending substantially vertically. Preferably, a rotation device (4) is provided between the floor and the seat cushion, the rotation device being configured to enable rotation about the selected one of the multiple rotation axes while restricting rotation about any of the remaining rotation axes.

In the present invention, a seatbelt device is provided with: a seat state determination unit that determines the state of a seat; a movable support section that supports a seatbelt within a range of possible movement on a seat back; a movement mechanism that, with a motor, moves the movable support section within the range of possible movement; and a motor control unit that controls the motor in accordance with the usage state of the seat determined by the seat state determination unit. Due to this configuration, the position of the seatbelt is made optimal for an occupant, and the comfort of the occupant is thus improved.

An assembly includes a base and a seatbelt anchor. The seatbelt anchor has a first end defining a circular hole pivotally supported by the base and a second end fixed in position relative to the first end. The assembly includes a buckle fixed in position relative to the second end. The assembly includes a pyrotechnic actuator secured to the base. The assembly includes a connector extending from the pyrotechnic actuator to the seatbelt anchor.

An assembly includes a webbing. The assembly includes a first webbing guide receiving the webbing. The assembly includes a second webbing guide receiving the webbing and releasably secured to the first webbing guide. The assembly includes an actuator. The assembly includes a cable secured to the actuator and to the second webbing guide.

In a lift-up buckle device, a slider and a shoe move forward and a buckle is moved to a stowed position. The shoe impacts against a protruding portion at a lower portion of a damper and interferes with a housing via the lower portion of the damper. Thus, the forward movement of the slider and shoe is stopped, while the damper absorbs an impact against the slider and shoe. Therefore, an amount of the impact against the slider and shoe that is absorbed by the damper may be increased by the protruding portion, and the damper may absorb the impact against the slider and shoe effectively.

Web adjusters and other web connecting devices for use with restraint systems are described herein. In some embodiments, web adjusters, such as tilt-lock web adjusters, can include web gripping features on an edge portion of a web aperture to prevent a web that is joined to the web adjuster from sliding or otherwise moving to one side of the web aperture or the other when the web is pulled in a direction that is not perpendicular to the edge. In some embodiments, the web gripping features can include alternating recessed and raised edge portions.

A buckle assembly comprises a buckle base bracket including at least one buckle base bracket ramp stop and at least one buckle base bracket reset ramp, and a buckle adjustment assembly. The buckle adjustment assembly includes a buckle strap coupled to the buckle base bracket such that the buckle adjustment assembly is capable of moving linearly along the buckle base bracket, a buckle head attached to the buckle strap, and a position locking unit coupled to the buckle strap, the position locking unit including a locking cam configured to prevent the buckle adjustment assembly from moving toward the proximal end of the buckle base bracket, and engage with a ramp surface of the buckle base bracket reset ramp to over-rotate the locking cam into a disengaged position such that the buckle adjustment assembly is movable in the first linear direction.
