An unlocking lever device includes: a lever member which is operated to rotate to allow a locking mechanism to perform an unlocking operation; a sign member which is stored in a storage recessed portion provided in the lever member; a bias member which biases the sign member in a direction of protrusion from the storage recessed portion; and an inclined surface which regulates the protrusion of the sign member from the storage recessed portion in accordance with a position of rotation of the lever member by being abut against the sign member, and generates a bias force which allows the lever member to rotate.

Unlocking lever device

A seat apparatus for a vehicle includes: an unlocking lever that is operated so as to unfix a seat from a vehicle floor; and a control switch that is operated in order for the seat to switch between a deployed state in which the seat is supported on the vehicle floor and a folded state in which the seat is retracted in a concave retraction portion of the vehicle floor, when a support member of the seat is driven via the driving of an actuator, wherein the unlocking lever is provided in a back surface of a seatback which is disposed at an opening end of the concave retraction portion when the seatback is folded forward and the seat is retracted, and the control switch is provided integrally with the unlocking lever.

Seat apparatus for vehicle

The present invention provides a lock device for locking by inserting a striker into a base member. The lock device includes a latch, which is disposed on the base member and constrains and releases the striker, and a pawl, which holds the latch. Backlash of the latch is limited by a simple structure. A cam member is rotationally connected to the base member by a rotation shaft different from that of the pawl. An engaging protrusion and recess are formed on the pawl and cam member, respectively. When the pawl is at an allowable position, the protrusion and recess are engaged with each other to hold the cam member. The engagement is released when the pawl rotates to a holding position, engaging the cam member with the latch, which is at a locked position, thereby rotating the latch such that the striker contacts the bottom surface of a base groove.

Vehicle lock

A seat for a vehicle includes a seat cushion frame reciprocating between seating and retracted positions, a seat back frame rotatable between standing and forward-tilted positions, a head rest movable between stationary and retracted positions, a pair of links provided at both end portions of the seat cushion frame on a floor in a lateral direction of the vehicle, a guide member including a guide groove extending between the seating and retracted positions, a slide member arranged at the seat cushion frame and sliding along the guide groove, a head rest retaining device retaining the head rest in the stationary position, a rotary member supported by the seat back frame and rotated by the slide member, and an interlocking device arranged between the rotary member and the head rest retaining device and releasing the head rest from the stationary position in accordance with a rotation of the rotary member.

Seat for vehicle

A vehicle seat includes an operating member that is provided for a seat back. The operating member is operated to release locking of a seat cushion to a floor and to release rotation-sopped state of a reclining device. By operating the operating member, a first link rotatably provided for the seat back is operated in one rotation direction to thereby turn a second link rotatably provided for a base frame so that locking of the seat cushion to the floor is released. When the seat back is tilted forward, the first link is moved together with the seat back in a direction to be separated from the second link, that is, in a direction opposite to a direction in which the first link turns the second link.

Vehicle seat

A lock mechanism for an electric retractable seat for a vehicle, includes a seat cushion frame, a seat back frame, a guide groove, a latch including an engagement opening portion, a slide member disengaging from the engagement opening portion when the latch is in an unlocked position, engaging with the engagement opening portion during a movement of the seat cushion frame to the seating position, and being locked between the guide groove and the engagement opening portion when the latch is in a locked position, a pawl for restricting the latch from pivoting when the pawl is in a restricted position, and allowing the latch to pivot when the pawl is in a released position, a releasing member for rotating the pawl.

Lock mechanism for electric retractable seat for vehicle

A lock apparatus for a vehicle seat includes a protruding portion formed at the side of a seat cushion so as to protrude therefrom, the seat cushion being movable between a usable position and a retracted position, a guide wall member having a guide groove with which the protruding portion is engaged, a latch formed with an opening portion within which the protruding portion is engagable, a sliding member a sliding surface, a latch biasing member, a pawl, a cam surface formed at the pawl for rotating the latch so as to sandwich the protruding portion, a pawl biasing member, a releasing lever and a releasing member formed so as to protrude from the releasing lever in order to rotate the pawl by pressing a releasing portion in a direction against the biasing force applied to the pawl by the pawl biasing member.

Lock apparatus for vehicle seat

A seat apparatus for a vehicle includes a first lock mechanism switching between a first locked state and a first lock-released state and a second lock mechanism switching between a second locked state and a second lock-released state. The first lock mechanism includes a restraining member and a releasing member. The restraining member restrains a pivotal movement of a seatback at a predetermined angle position, at which the seatback does not interfere with a seat cushion moving between a first position and a second position thereof, when the second lock mechanism is in the second lock-released state. The releasing member is linked to the restraining member and releases a restriction to the pivotal movement of the seatback by being moved in association with a movement of the seat cushion when the second lock mechanism is in the second lock-released state.
