A system for generating a vibration of a seat of a vehicle in sync with music outputted from an audio device using an electric motor included in the seat to adjust the seat in forward and backward directions and upward and downward directions includes: an electric-motor multiple-control circuit configured to receive a signal of a seat position adjustment switch and a signal of an audio switch, generate a driving current required to vibrate the seat, and output the driving current to an electric motor. The electric motor receives a signal from the electric-motor multiple-control circuit and generates a motor torque while being driven, and the generated motor torque is transferred to the seat to generate a target vibration in the seat.

Disclosed is a seat elevating device including a support unit, a driving unit, and an elevating unit. The support unit is structured such that a first end is coupled to a body of a vehicle and a second end extends upward from the first end and is connected to a first end and a second end of a bar. The driving unit is coupled to an inner side surface of the support unit and equipped with a drive shaft on a side surface thereof. The elevating unit is connected to the drive shaft via a gear unit and is provided with a groove to receive the bar so that the bar slides along the groove. The elevating unit is slidable because it is engaged with the gear unit connected to the drive shaft via a rack gear that extends in parallel with a sliding movement direction of the elevating unit.

It is provided an adjusting device for the longitudinal adjustment of a vehicle seat, comprising at least one rail for defining a longitudinal seat axis along which a seat base of the vehicle seat is adjustable, and for supporting at least one adjusting unit of the adjusting device, and at least two shiftably guided adjusting units arranged one behind the other along the longitudinal seat axis, to which the seat base is to be fixed in order to be adjustable along the longitudinal seat axis. The at least two adjusting units are adjustable relative to each other along the longitudinal seat axis, and each adjusting unit is assigned a separate drive for the power-operated adjustment along the longitudinal seat axis.

A method and apparatus for automatically arranging seats of an autonomous vehicle enable seats to be remotely changed between a standard arrangement mode and a final target arrangement mode. The apparatus includes a manipulation device configured to generate a signal corresponding to a target arrangement mode of seats through manipulation by a passenger, seat motors respectively provided in the seats so as to control positions and postures of the seats, seat controllers for controlling operation of the seat motors, and a vehicle controller configured to transmit a signal from the manipulation device to the seat controllers, transmit an abnormal signal indicating jamming of the seats to the manipulation device or control the seat controllers provided in the vehicle. As a result, it is possible to easily change the seats to a desired arrangement mode in an autonomous vehicle without interference with peripheral components during movement of the seats.

A vehicle seat adjustment device includes a first adjustment mechanism, a second adjustment mechanism, and a controller. The first adjustment mechanism is moved in a first direction upon driving of a first motor to adjust a position of a vehicle seat. The second adjustment mechanism is moved in both the first direction and a second direction orthogonal to the first direction upon driving of a second motor to adjust the position of the vehicle seat. The controller controls and drives the first motor and the second motor. A speed at which the second adjustment mechanism is moved in the first direction is lower than or equal to a speed at which the first adjustment mechanism is moved in the first direction. When the second motor needs to be driven, the controller drives the second motor while driving the first motor.

A pumping device for a seat of a vehicle, in which a cam supporter supports a clutch cam to be balanced in the pumping device, thereby minimizing movement of the clutch cam due to an external force reversely input, and the cam supporter guides movements of brake rollers, thereby causing braking operation by the brake rollers to be precisely performed and improving operating performance.

A swivel device for vehicle seats may rotate a seat mounted inside a vehicle at 180° or more and firmly fix the seat at a normal position before and after rotation. The swivel device includes: a base plate provided with a plurality of first locking members; a swivel plate disposed on the base plate to be rotated by a second motor; a rotary force transmission mechanism mounted on an output shaft of the second motor and the swivel plate to transmit a rotary force of the second motor to the swivel plate; an elevating plate provided with a plurality of second locking members separably coupled to the plurality of first locking members and formed on a lower surface of the elevating plate; and a first motor mounted on an upper surface of the elevating plate to transmit a rotary force to the lead screw.

A pumping device for a seat of a vehicle is proposed. In the pumping device, a plurality of pressure members is provided along an outer circumferential surface of a brake drum, and braking operation is performed through the pressure members moved when the brake drum rotates, so that friction between the brake drum and a housing can be avoided and thus deterioration of operational performance is prevented. In addition, the shape of the brake drum is simplified and the number of components is reduced, so that weight and size of the pumping device, and production cost are reduced, and fuel efficiency increases.

Aspects of the present disclosure include a vehicle having a passenger assistance system for facilitating ingress and egress of passengers. The vehicle may include a plurality of wheels. The vehicle may include a body including at least one doorway supported on the plurality of wheels via a suspension. The vehicle may include a door movable between an open position and a closed position covering the at least one doorway. The vehicle may include a first platform movable between a horizontal position beneath a bottom of the doorway and a stowed position parallel to the door. The vehicle may include an occupant compartment within the body. The occupant compartment may include a seat rotatable to face the doorway in an ingress or egress mode. The occupant compartment may include a robotic arm configured to extend along an ingress or egress path through the doorway.

Proposed is a clutch cam for a pumping device, wherein the shape of the clutch cam and the coupling structure between the clutch cam and parts coupled thereto are changed to reduce manufacturing cost and improve assembly performance. The clutch cam includes: a cam part having a cam profile provided along an outer circumferential surface thereof relative to a rotating axis of a center thereof; a first protrusion part provided on a side of the cam part by protruding therefrom toward the lever bracket on the same rotating axis as the rotating axis, and fitted to a fixing hole provided in the lever bracket; and a second protrusion part provided on the side of the cam part by protruding therefrom toward the lever bracket on the same rotating axis as the rotating axis, and fitted to an angle determination hole provided in the housing.
