An object of the present invention is to provide a seat for a vehicle which is capable of smoothly and stably adjusting the reclining of a seat back by driving an electrical reclining motor 34, even if the electrical reclining motor 34 is diagonally mounted on a seat back frame structure in a case where the electrical reclining motor 34 is fixedly connected on a seat back frame structure, or even if the electrical reclining motor 34 becomes inclined due to a deformation of the seat back frame structure after such a fixedly connection.

There is provided a seat 10 for a vehicle comprising a seat back frame structure 12 a lower end of which is connected to a rear end of a seat cushion frame structure 14 in such a way that the seat back frame structure 12 can be inclined relative to the seat cushion frame structure 14, said seat back frame structure 12 including a pair of side frames 20A,B each of which extends in a vertical direction of the vehicle, said seat 10 for the vehicle further comprising a through-hole 28 provided on a lower end portion of each of the pair of side frames 20A,B, a connecting rod 30 extending through each of the through-holes 28 so as to be rotatable about a horizontal direction, an electrical reclining motor 34 rotating said connecting rod 30 and provided along the one of side surfaces of the one of said pair of side frames 20A,B, and a reclining apparatus 16 provided on the other of the side surfaces of each of said pair of side frames 20A,B, a bolt through-hole 72 being provided on a non-rotational driven solid portion of said electrical reclining motor 34, a bolt 74 which fits into said bolt through-hole 72 is provided for fixedly bolting said electrical reclining motor 34 on said one of the side surfaces of the one of the pair of side frames 20A,B, said bolt 74 comprising a head portion 76 and a shank portion 78 with a circular cross-section, said shank portion 78 comprises an enlarged-diameter portion 82 on its end portion and a reduced-diameter portion 84 adjacent to the enlarged-diameter portion 82 with being concentric to each other.

A vehicle seat comprising a seatback pivoting relative to a frame around the first transverse axis, a seat cushion pivoting relative to the seatback around a second transverse axis, a link pivoting relative to the seat cushion around a third transverse axis, wherein the link is further pivoting relative to the frame around a fourth transverse axis, a mechanism for releasing the angular position of the seatback relative to the frame around the first transverse axis, and an actuator, attached under the seat cushion. The angular position of the seatback relative to the frame released, the actuator commands a movement of the link relative to the seat cushion and consequently of the seatback relative to the seat cushion, from a comfort position of the seat to a flat floor position.

A thigh-extension for a vehicle seat includes a metallic thigh-extension plate, an extension track defined by a low-friction resin overmolded onto the thigh-extension plate and a thigh-extension slider having an integral groove slidably engaged with the extension track to define a plurality of thigh-extension positions.

A motor-driven hinge device may include a hypocycloid hinge mechanism driven by a drive shaft, two metal side plates intended for connection to the seating portion and to the backrest, a brushless motor, and a planetary gear train positioned between the brushless motor and the drive shaft. The planetary gear train may include a sun gear connected to the motor rotor, and a plurality of planet gears, each planet gear having a first set of teeth engaging with the sun gear and with a first stationary ring gear, and a second set of teeth engaging with a second ring gear rigid with the drive shaft.

A longitudinal adjuster for a vehicle seat may have a rail assembly having two rail pairs of seat rails. The respective rail pair has a fixed seat rail and a seat rail that is movable relative to the fixed seat rail. The rail assembly may also have a motor unit and a gearbox unit, which couples the motor unit and the movable seat rail. The rail assembly may also comprise a holder for receiving a gearbox housing of the gearbox unit. The holder is arranged with the gearbox unit in a hollow space formed by the one rail pair and is fixed to the movable seat rail. The holder is formed so as to be open at one end and closed at the opposite end. The holder has at least one stiffening element at the open end.

Disclosed is a device for controlling comfort equipment of a passenger transport vehicle seat module. With the control device including: a control unit, a transmitter/receiver intended to receive an adjusting command and to transmit it to the control unit; the control unit being able to transmit the adjusting command received to a piece of comfort equipment, a locking device including a maneuvering member, the locking device prevents the transmission of the adjusting command of the transmitter/receiver to the piece of comfort equipment, when the maneuvering member is actuated.

A longitudinal adjuster for a motor vehicle seat may have a seat rail that can be connected to the vehicle seat, and a floor rail, which can be connected to a vehicle floor and on which the seat rail is displaceably guided. The longitudinal adjuster may have a drive device for adjusting the seat rail relative to the floor rail along the longitudinal direction. The drive device may have a spindle fixed to the floor rail or to the seat rail. A rotatable spindle nut may be mounted on the spindle via a thread engagement. An electric motor may be operatively connected to the spindle nut for driving the spindle nut. A drive-side output shaft of the electric motor may be oriented parallel to the spindle. The floor rail has a cut-out and the electric motor is at least partly arranged through the cut-out.

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 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.
