Disclosed is a locking device for a walk-in seat of a vehicle capable of stably maintaining the locked state of the walk-in seat prior to a walk-in operation. An object of the present invention is to provide a locking device for a walk-in seat of a vehicle capable of stably maintaining the locked state of the walk-in seat prior to a walk-in operation (that is, the locked state of a drive plate for the walk-in operation of the seat) even if the engagement between the drive plate and a pawl is released due to deformation caused by a torsional load applied to a connection frame of the seat by additionally providing a separate component configured to prevent the drive plate from being rotated in an unlocking direction when a load is applied to a seat belt buckle.

A latch device includes a latch engageable with a rod portion of a striker, and is capable of transition to a locked state in which the latch is engaged with the rod portion and to an unlocked state in which the latch is disengaged from the rod portion, and includes a first shaft member that supports the latch in a manner that permits the latch to rotate, and a base member that supports the first shaft member. The base member is a unitary member which includes a first support wall disposed on one side of the latch and configured to support one end of the first shaft member, a second support wall disposed on an other side of the latch and configured to support an other end of the first shaft member, and a connecting wall that connects the first support wall and the second support wall.

A rotatable armrest includes: a housing; a button system; and a hinge system engaged to the button system, in which the button system and the hinge system are provided in the housing, in which the hinge system includes a hinge shaft, and the rotatable armrest is fixed at a first position, a second position, or a third position by being rotated about the hinge shaft, and in which the rotatable armrest is configured to be positioned to be folded downward at the first position, the rotatable armrest is configured to be positioned to be directed forward horizontally at the second position, and the rotatable armrest is configured to be positioned to be directed rearward horizontally at the third position.

The invention relates to a headrest for a vehicle seat, comprising a first part; a second part that is able to rotate with respect to the first part; and a control rod for the relative movement between the first part and the second part; wherein the second part comprises an arcuate opening for receiving the rod, the opening comprising cavities; and wherein the rod is movable between an adjustment position in which the rod does not prevent the relative rotational movement between the first part and the second part; and a locked position in which the rod is trapped inside one of the cavities of the opening, thus preventing relative rotational movement between the first part and the second part.

A latch device includes a latch engageable with a rod portion of a striker, and is capable of transition to a locked state in which the latch is engaged with the rod portion and to an unlocked state in which the latch is disengaged from the rod portion, and includes a first shaft member that supports the latch in a manner that permits the latch to rotate, and a base member that supports the first shaft member. The base member is a unitary member which includes a first support wall disposed on one side of the latch and configured to support one end of the first shaft member, a second support wall disposed on an other side of the latch and configured to support an other end of the first shaft member, and a connecting wall that connects the first support wall and the second support wall.

In the case of a seat with an armrest on an automobile, an armrest lock mechanism may be released by, for example, the gravitational acceleration(G) in the event of vehicle collision. Accordingly, it is necessary to provide an anti-G spring for biasing to prevent the lock mechanism from being easily released. The purpose of the present invention is to provide an armrest unlocking device that enables a decrease in size of the anti-G spring. In order to solve the problem, provided is an armrest unlocking device in gear, the device operating such that the locking of the lock gear and the sector gear can be released by operating a lever link bracket so as to raise the lock gear, wherein the lock gear has a center of rotation thereof aligned with the position of the center of gravity.

A ratcheting armrest assembly includes an articulating frame assembly. Also included is a ratchet anchor operatively coupled to the articulating frame assembly for rotation with the articulating frame assembly. Further included is an anchor assembly operatively coupled to the articulating frame assembly. Yet further included is a ratchet operatively coupled to the anchor assembly. The ratchet includes a first plurality of teeth and the ratchet anchor including a second plurality of teeth, wherein the first plurality of teeth and the second plurality of teeth are engageable with each other, the second plurality of teeth free to rotate relative to the first plurality of teeth in a first rotational direction and self-locking with the first plurality of teeth in a second rotational direction. Also included is a directional spring biasing the ratchet in the second direction in a first orientation and in the first direction in a second orientation.

A torque transfer control mechanism that suppresses output-side displacement, and including a rotation control unit that maintains a locked state when an input torque rotating a transfer mechanism is not applied, and releases the locked state when the transfer mechanism rotates. The rotation control unit includes an internal gear and lock plates that include outer teeth that can engage with inner teeth of the internal gear. When an input torque is not applied, the inner teeth of the internal gear engage with the outer teeth of the lock plates, and when the transfer mechanism is rotated, engagement between the inner teeth and the outer teeth is released. Thus, even when torque is applied from the output unit side, engagement between the inner teeth and the outer teeth is not released by the torque.

To improve comfort, a motor vehicle seat has at least one cushion body, at least one cover concealing the cushion body at least in part, and at least one tensioner, which is operatively connected to the cover by a first end and is designed to adjust the cover tension. The tensioner is fixed by a second end to a clamping device. The clamping device is designed to modify and fix the distance of the tensioner from the first end thereof to the second end thereof and the clamping device is designed to be operated after completion of the motor vehicle seat.

An accessory for a vehicle has a base and a pivot part that can be pivoted relative to the base in opposite first and second pivoting direction between first and second end positions. A first latch and a second latch can lock the pivoting movement of the pivot part in at least one of the directions. An actuator automatically and/or manually moves the latches between a latched position in which the first latch and the second latch engaged and a released position in which the latches disengaged. One of the latches has a rotatable wheel rotatable having first blocking surfaces. The base or the pivot part has a first teeth engaging second teeth of the wheel. The other latch is provided with second blocking surfaces that engage the first blocking surfaces in the latched position and disengage therefrom in the released position.
