A mechanism for rotating a vehicle seat body and a mechanism for restraining rotation of the seat body are partially shared, reducing the number of parts. The seat includes a seat body, a seat rotation mechanism, a gear forming member having a rotation gear, a drive gear meshable with the rotation gear, and an actuator for rotating the drive gear. The seat further includes a moving mechanism that relatively moves the drive gear and the gear forming member in a direction of a rotation restraint position such that the drive gear is placed in such a position so as to interfere with the gear forming member when the seat body rotates to a first position and when the seat body is urged to rotate in a direction of a second position while the drive gear is in such a position so as to not mesh with the rotation gear.

Vehicle seat

The present invention provides a mechanism that can release the rotation lock mechanism without using an actuator. In the present vehicle seat, a nut () is moved upon rotation of a screw shaft () so that the seat body is moved in the lateral direction of the vehicle. When the nut () is moved by a desired distance, a guide roller () is pushed so that an operation arm () is moved parallel with the guide roller. As a result, a lock plate () is rotated in an unlock direction so that a claw () is disengaged from a striker ().

Seat for vehicle

It is one object of this invention to provide a technique that is effective in diminishing the range of fluctuation of a load applied to a drive source when a seat main body in a vehicle seat moving apparatus is moved between a raised position and a lowered position. For this purpose, this invention provides a vehicle seat moving apparatus constructed as follows. Provided on a rotation base, for rotating a seat main bodybetween a position where it faces the front side of the vehicle and a position where it faces a door opening, is a widthwise slide basethat moves horizontally in the vehicle width direction while the seat main bodyfaces the door opening. The seat main bodyis supported by the slide basevia four-bar linkage mechanisms. Guide rollersare attached to upper link armsof the four-bar linkage mechanisms. The guide rollersare placed on cam surfaces of cam platesprovided to the rotation base. The cam surfaces have continuously extending inclined guide surfacesthat guide such that the guide rollersmove obliquely upwards when the widthwise slide basemoves.

Seat moving device for vehicle

A longitudinal support base is provided with a rotating support base that can be slide in a longitudinal direction of the vehicle. A seat body is placed on the rotating support base via a rotary disc so as to rotate. The longitudinal support base is provided with an intermediate gear that is engaged with a rack extending in the longitudinal direction of the vehicle seat. The seat body side is provided with a pinion gear that is engaged with the intermediate gear The rotary disc is rotated by means of a driving force of an electric motor Thus, when the electric motor is rotated, the seat body rotates and slides in the longitudinal direction.

Rotating vehicle seat

With respect to a rotating seat for a vehicle, for example, for the elderly or the handicapped, the known art requires two operations of moving a seat body forward and rotating it to a door opening, and is thus poor in usability. Further, if the seat is positioned to the front such that the seat can be rotated at that position, the space close to occupant's feet is sacrificed. It is, accordingly, an object of the present invention to provide a rotating vehicle seat having excellent usability without sacrificing the space close to occupant's feet. A rotating vehicle seat of the present invention includes a rotating support base for rotatably supporting a seat body a longitudinal support base for supporting and moving the rotating support base in a longitudinal direction of a vehicle, and a coupling arrangement means disposed between the seat body and the longitudinal support base for coupling the rotational movement and the longitudinal movement of the seat body.

A rotating vehicle seat allows space close to an occupant's feet to be used efficiently. The rotating seat has a seat body supported by a rotary disc The rotary disc is mounted at a position that is displaced to a door opening side with respect to a center HP of a seat cushion. A pinion gear an intermediate gear and a rack engage each other so that the rotational movement and the longitudinal movement of the seat body are coupled to each other.
