The embodiments described and claimed herein are improved vehicle access systems. In particular, one embodiment includes three compact, motorized mechanisms for pivoting a passenger seat toward a door opening, extending the passenger seat outside the door opening, lowering the passenger seat, and tilting the passenger seat to help the passenger stand. The first mechanism concurrently pivots the passenger seat and moves it sideways during the pivoting operation so that it is aligned with the door opening. The second mechanism extends the passenger seat outside the door opening. The third mechanism lowers the seat.

An adjustment system for a seat has a first bearing shell for receiving a seat surface and/or a seat backrest, a second bearing shell for connecting to a substructure, a first wedge-shaped adjustment ring, which is rotatably mounted on the first bearing shell, a second wedge-shaped adjustment ring, which is rotatably mounted on the second bearing shell and rotatably mounted on the first adjustment ring, a first drive for rotating the first adjustment ring relative to the second adjustment ring, a second drive for rotating the second adjustment ring relative to the second bearing shell, and a blockade mechanism for electively connecting the first bearing shell and the second bearing shell for conjoint rotation.

A vehicle seat rotates in response to activation of an electric motor. The electric motor is part of a non-back-drivable mechanism such that it acts to lock the seat in position. The seat mechanism is assembled from stamped components for efficient manufacturing. A bracket includes integrally formed gear teeth which mesh with gear teeth driven by the electric motor. The bracket is held between two stamped parts using four-point angular contact ball bearings. The races of the ball bearings are stamped into the respective stamped parts.

The processor is configured to acquire position information of a first seat arrangement representing current seat positions of plural seats that are configured to be capable of moving in a cabin interior, acquire position information of a second seat arrangement representing post-movement seat positions of the plural seats, identify a movement path of a moving seat of the plural seats when moving from the acquired first seat arrangement to the acquired second seat arrangement, detect occupants sitting on the plural seats, and operate the moving seat so as to move the moving seat along the identified movement path. In a case in which an occupant sitting on another seat disposed peripherally to the movement path of the moving seat has been detected, the processor is configured to either control so as to execute any one action of the group consisting of reducing a movement speed of the moving seat, canceling movement of the moving seat, and shortening a movement distance of the moving seat.

A multipurpose vehicle includes a vehicle body, an accommodating section (5) provided for the vehicle body and including a seat (20) in which an occupant is able to sit, and a changing mechanism (23) configured to change the horizontal orientation of the seat (20), wherein the changing mechanism (23) is configured to change the horizontal orientation of the seat so that the seat faces at least a predetermined first direction d1 or a predetermined second direction d2.

A rotating vehicle seat includes a backrest attached to a seat base frame and arranged to be rotatably adjustable around a first horizontal axis, a seat base attached to the frame and arranged to be rotatably adjustable around a second horizontal axis parallel to the first horizontal axis, a gear mechanism connected to the frame arranged to rotate the frame from a forward facing position to a backward facing position, wherein the gear mechanism comprises a track, and the frame comprises a guide that is configured to engage the track, such that when the gear mechanism is actuated, the frame is translated in a xy-plane and is rotated around a first vertical axis, and wherein the backrest and the seat base, respectively, are arranged to be folded upwards during at least part of the rotation of the frame around the first vertical axis.

A seat assembly for a mobility scooter has a seat portion for supporting an operator of the mobility scooter in use and a yoke arranged to receive the seat portion. The yoke has a mounting formation for mounting to a support member of the mobility scooter such that the yoke is removably mounted atop the support member and the seat portion is removably mounted atop the yoke in use. The yoke also has an attachment formation for releasable attachment of an arm-rest and a back-rest for the seat portion. The seat portion can be lifted off the yoke as a first component. The yoke can be lifted off the support member as a further component when removing the seat assembly from the mobility scooter.

A swivel plate assembly is provided that comprises a first swivel plate coupled to a second swivel plate. Each of the first and second swivel plates includes a first portion and a second portion. A channel is defined by the first swivel plate and the second swivel plate. A ball bearing assembly is positioned within the channel. A ball bearing of the ball bearing assembly is positioned substantially flush with the first and second swivel plates.

A seat assembly includes a track assembly having a swivel mechanism slideably supported along the track assembly. A base frame is supported on the swivel mechanism between forward-facing and rearward-facing configurations. A seatback is pivotally coupled to the base frame by a recliner mechanism. A seat portion is pivotally coupled to the base frame and includes a front edge. The seat portion is operable between first and second positions, such that the front edge of the seat portion defines a forward-most portion of the seat assembly when the seat portion is in the first position. Further, the front edge of the seat portion is vertically juxtaposed over the base frame when the seat portion is in the second position.

A moving and locking device for a vehicle seat includes: a lower frame mounted on a bottom surface of a seat cushion; a plurality of wheels disposed underneath the lower frame in such a manner that the plurality of wheels roll on a floor panel; and a vacuum adsorption device disposed inside the lower frame and configured to be adsorbed on the floor panel by vacuum force. The vehicle seat is configured to be moved to the desired position through the rolling motion of the plurality of wheels, and configured to be locked at the desired position through vacuum adsorption of the vacuum adsorption device on the floor panel.
