An electric lock for a fold-down seat of a motor vehicle is situated inside a housing. The lock includes a locking means, a blocking element, a transmission lever attached to the blocking element so as to move it between a position of blocking the locking means in the catch retention position and a position in which it is effaced with respect to the movement of the locking means. The lock includes an actuator comprising an electric motor, the actuator being able to move the transmission lever. The transmission lever of the lock is able to move about an axis of rotation and has two arms extending radially from the axis, the first arm at its end having a handle and the second arm at its end having a means of attachment to the blocking element.

A seat device that can reliably prevent a rotation operation of a seat by a seated person, in a long state where the back of the seat is along a wall. A rotation lock mechanism (60) that can restrain the rotation of a seat (1), a rotation operation unit (200) that performs a release operation of restraint by the rotation lock mechanism (60), and a rotation operation prevention mechanism (210) that disables the release operation in the rotation operation unit (200), when the seat (1) is in the long state are included. The rotation operation prevention mechanism (210) includes an engaging unit (211) provided in the leg stand (11), and an engaged unit (207) that is provided in the rotation operation unit (200) in the movable stand (20), and disables the release operation in the rotation operation unit (200) by being engaged with the engaging unit (211) when the seat (1) is in the long state.

A seat adjustment system for a vehicle seat is provided. The seat adjustment system includes a seat body; at least one actuating unit, configured to adjust a support of the seat body; a sensing unit, configured to obtain and provide seat information and body shape data of a back of an occupant; and a control unit, configured to control the at least one actuating unit; wherein when one parameter of the seat body changes, the control unit makes a portion of the body shape data of the occupant in a pre-defined range via the at least one actuating unit.

A sliding unit for a vehicle, the sliding unit may include a rail provided on the vehicle; a fixing portion formed of a material through which magnetism is flowable and provided along a direction in which the rail extends; a moving portion that is slidable along the rail; and a magnetic module provided in the moving portion, disposed toward the fixing portion, and selectively locked to the fixing portion by a magnetic path to selectively fix the moving portion to the rail.

A central electronic control unit (ECU, Ref. 14) is provided for controlling at least one bi-directional direct current (DC) motor (106) attached to a first vehicle seat and at least one electronic device attached to a second vehicle seat. The central ECU includes a micro-controller configured to receive feedback on a positional status of the bi-directional DC motor from a Hall Effect sensor (130). The micro-controller is configured to receive input instructions for the bi-directional DC motor and the electronic device. The micro-controller creates command instructions based in part on the received feedback and received input instructions. The central ECU selectively provides pulse width modulated (PWM) power to the bi-directional DC motor attached to the first vehicle seat and selectively provides power to the electronic device attached to the second vehicle seat in response to the command instructions from the micro-controller.

A seat position detection apparatus for a vehicle seat which is guided using a seat rail in a floor rail of the vehicle. The seat position detection apparatus has a lock for the longitudinal setting of the seat rail and the floor rail in relation to one another, and a mechanical memory device that has a position determination unit and a position detection unit, which may be started symmetrically from both directions of the longitudinal adjustment of the vehicle seat to define a vehicle seat position.

A power long rail assembly is attached to a vehicle floor for repositioning vehicle seats in a vehicle between a plurality of seating positions. The power long rail assembly includes a fixed long rail and a power rail drive assembly configured to travel along the fixed long rail. The power rail drive assembly has an upper channel having a driving wheel configured to frictionally and/or meshingly engage with the fixed long rail, a fore/aft motor operatively coupled to the driving wheel, a latch assembly for locking the upper channel to the fixed long rail, and a latch release mechanism having a latch motor operatively coupled to a release plunger for automatically unlocking the latch assembly from the fixed long rail, and a fore/aft button operatively coupled to the fore/aft motor and to the latch motor to selectively activate the fore/aft motor and the latch motor.

A rotational brake assembly comprises: a swivel disc having an outer diameter and a plurality of locking holes proximate the outer diameter; a cam having an angled slot; a lifting pin located within the angled slot of the cam; and a rotational brake pin operably connected to the lifting pin. The cam in operation moves to at least one of a locked position and an unlocked position based on an input. The lifting pin in operation moves along the angled slot when the cam moves. The rotational brake pin in operation moves due to motion of the cam. The rotational brake pin in operation moves from an engaged position with the swivel disc to a disengaged position, when the cam moves from the locked to the unlocked position. The rotational brake pin in operation moves to the engaged position, when the cam moves to the locked position.

A seat locking mechanism comprises: a plurality of positional brake mechanisms including a longitudinal brake assembly, a lateral brake assembly, and a rotational brake assembly; and a carriage assembly operably connected to the plurality of positional brake mechanisms. The carriage assembly having a carriage tube and a carriage housing fixedly connected to the carriage tube. The carriage assembly in operation moves each of the plurality of positional brake mechanisms to at least one of a locked position and an unlocked position, when the carriage assembly rotates.

A seat locking mechanism comprises a plurality of positional brake mechanisms including a longitudinal brake assembly, a lateral brake assembly, and a rotational brake assembly; and an electric motor assembly operably connected to each of the plurality of positional brake mechanisms. The electric motor assembly comprises: a drive motor; a clutch system located between the drive motor and the plurality of positional brake mechanisms; and a solenoid operably connected to the clutch system. The solenoid in operation engages the clutch system to operably connect the electric motor to the plurality of positional brake mechanisms when the electric motor assembly is activated and disengages the clutch system to operably disconnect the electric motor to the plurality of positional brake mechanisms when the electric motor assembly is deactivated. The electric motor assembly in operation moves the plurality of positional brake mechanisms to at least one of a locked position and unlocked position.
