The drive unit has an actuating motor and an actuator that is displaceable via the actuating motor and connected to the second cross bar outside the first axis. The drive unit is mounted on the first cross bar and rotatable about a second axis of the first cross bar which is fixed in the two side rails.

The present disclosure provides a seat control system for a vehicle, which may sense whether passengers have been seated on a front seat and a rear seat, and easily implement sleep and rest postures of the front seat and the rear seat through the height adjustment, the reclining adjustment, and the like of the front seat and the rear seat according to the sensed result.

A defibrillation system may include a cardiac arrest detector detecting whether cardiac arrest of a passenger has occurred in a state of taking a seat of a self-driving vehicle and fastening a seatbelt of the vehicle; a passenger posture detection device detecting a posture of the passenger; a seat driving device changing the posture of the passenger into another posture in which the passenger lies down based on a detection signal of the passenger posture detection device when the cardiac arrest of the passenger occurs; a heart position detector configured to search for a position of a heart of the passenger; a defibrillation robot to perform a CPR method or a method using an AED on the heart of the passenger; and a controller controlling operation of the seat driving device, the heart position detector, and the defibrillation robot based on detection signals of the cardiac arrest detector and the passenger posture detection device.

An electric motor for reciprocating an object along a rod having a predetermined length is provided, comprising: a housing; a rotor unit that is mounted to the inside of the housing via a bearing to be rotatable and comprises a rotor shaft, which is axially-coupled to the rod to linearly reciprocate along the rod during rotation, and a plurality of magnets mounted along the circumference direction of the rotor shaft; and a stator unit comprising at least one stator core and a coil, the at least one stator core comprising a yoke portion of a closed loop shape that is built in the housing so as to surround the circumference of the rotor unit, and a plurality of slot portions extending from the yoke portion toward the rotor, and the coil being wound around at least one slot portion among the plurality of slot portions.

The disclosure discloses an automobile seat based on an inclined angle adjustment mechanism, including a seat body composed of a cushion skeleton, a backrest skeleton, and a base arranged under the seat body. The upper surface of the base is of a non-plane structure and includes a pedestal located at the lower part and a branch located at the upper part which is integrated or connected by a fixed member, the back of the pedestal is movably connected with the lower part of a third connection rod, the upper part of a seventh connection rod is movably connected with the front of a forth connection rod, and the middle of the seventh connection rod is movably connected with the upper end of the branch, and rotation points are located near the H point of the seat.

An automobile seat integrated with height adjustment and angle adjustment comprises a seat body comprising a pedestal skeleton and a backrest skeleton, a height adjustment mechanism comprising a bottom support, a rear connection rod, an upper connection rod and a front connection rod and an angle adjustment mechanism comprising the bottom support, an angle adjustment connection rod, a driving connection rod, a front connection rod and the upper connection rod, the bottom support, the front connection rod and the upper connection rod are common parts of the height adjustment mechanism and the angle adjustment mechanism, the bottom support, the rear connection rod, the upper connection rod and the front connection rod are successively adjacently connected by rotating pairs, and the rear connection rod is connected with a height adjustment driving source which drives the rear connection rod to move when working to realize the height adjustment of the automobile seat.

A headrest adjusting device for headrest adjustment with respect to a backrest may have a headrest mounting bracket and a slide device movable mounted on the headrest mounting bracket. The headrest mounting bracket may have a seat belt retainer movable mounted on the headrest mounting bracket. A seat structure for a vehicle seat may also have the headrest adjusting device.

A vehicle seat has a seat base, a carriage, and an adjusting device. The adjusting device is formed in such a way that the vehicle seat is adjustable vertically or the inclination is adjustable by the adjusting device. The adjusting device has a rotation device arranged on the carriage such that the seat base is rotatable relative to the carriage about a vertical axis by the rotation device. The adjusting device includes a strut, a first end of which is pivotably attached to the carriage or to a rotation base fixed to the carriage and a second end of which is pivotably attached to the seat base. The adjusting device has first and second linear actuators. The seat base is supported on the first linear actuator, the second linear actuator, and/or the strut. The first and second linear actuators cooperate to adjust the vehicle seat.

The invention relates to an apparatus for adjusting a seat position for a vehicle seat, which comprises at least one support element for a seat part and can be connected to a seat substructure, wherein the apparatus comprises at least one first limb and at least one second limb, wherein the limbs can be rotatably arranged on the seat substructure and the at least one support element, wherein a first angle α between the first limb and the support element can be adjusted by an angle adjustment device, wherein the at least one first limb and the at least one second limb each have a lever portion, and these are mechanically coupled, and wherein a change in the angle α causes a displacement of the at least one support element along a height axis Z, and a change in an angle of inclination θ of the support element.

A seat support assembly has a lower member with a first channel extending in a front-back direction of the seat support assembly and an upper member positioned above the lower member and having a second channel extending in the front-back direction. A first linkage has a lower end pivotably coupled to the lower member and translatable in the front-back direction by way of the first channel and an upper end pivotably coupled to the upper member. A second linkage has a lower end pivotably coupled to the lower member and an upper end pivotably coupled to the upper member and translatable in the front-back direction by way of the second channel. The first and second channels are offset from one another in the front-back direction.
