A vehicle seat of the present invention has an engaged member, an engagement member and a guide portion. The engagement member is provided on the seat body so as to be movable between a restraint position and a restraint release position. The engagement member is capable of moving to the restraint position, so as to be advanced to a position in which the engagement member faces the engaged member, and is capable of moving to the restraint release position, so as to be retracted to a position in which the engagement member does not face the engaged member. The guide portion is capable of moving the engagement member to the restraint position when the seat body moves to the retracted position, and is capable of moving the engagement member to the restraint release position when the seat body is advanced from the retracted position.

Vehicle seat

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 slide device, comprising first class members having spaces opening to sides formed in the longitudinal directions thereof and second class rail members positioned in the spaces, wherein either of the first and second class rail members movable relative to each other are formed in movable rail members and the other are formed in fixed rail members, the movable rail members are installed at both side parts of slide plates, the slide plates are positioned on brackets parallel with each other, and the movable rail member installed on the slide plate is supported by the fixed rail member installed on the slide plate.

Slide device

A lift-up mechanism ( ) installed inside a vehicle serves to move a seat unit ( ) into or out of the vehicle. The seat unit ( ) is used as a passenger seat inside the vehicle and as a wheelchair outside the vehicle. Connecting plates ( ) are disposed on the lift-up mechanism ( ) permit the lift-up mechanism ( ) to be connected to the seat unit ( ) by inserting the connecting plates into connecting recesses ( ) formed in the seat unit ( ). Front wheels ( ) and rear wheels ( ) of the seat unit ( ) can be retracted and extended. A drive unit having an electric motor or similar drive may be provided to retract and extend the front wheels ( ) and the rear wheels ( ). An attitude changing arrangement may be provided to automatically change the attitude of the front wheels ( ) when the front wheels ( ) and the rear wheels ( ) are retracted.

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.
