A vehicle seating assembly includes a seat frame seat frame having a seat frame, a first and second extendable members disposed on a forward portion of the seat frame and operable between an extended position and a retracted position. Each of the first and second extendable members comprises a movable housing, a support base attached to the seat frame and slidably coupled to the movable housing, a trim cover stock partially disposed above an upper surface of the movable housing and having a first fixed upper edge and a second movable lower edge, and a linkage system operatively coupling the movable housing to the second movable lower edge of the trim cover stock to maintain tension on the trim cover stock as either of the first and second extendable members is operated between the extended and retracted positions.

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 seat cushion extension apparatus for a vehicle seat includes an extension unit slidable from a front end portion of a seat frame in a vehicle to a position disposed forwards of the front end portion of the seat frame, locking units for locking the extension unit with respect to the seat frame at a locking position, and allowing the extension unit to be slidable such that the extension unit protrudes forwards of the seat frame at a release position, and a lever for controlling the locking units between the locking position and the release position. The extension unit is supported by guide shafts to be movable forwards and rearwards in housings fixed to the seat frame. The guide shafts are locked in the housings at the locking position and are movable with respect to the seat frame at the release position.

An extendable seat base for a seat of a vehicle is disclosed. The seat base includes an outer cushion, a cord, and a motor. The outer cushion forms a top of the seat base and extends, in one unitarily formed piece, down a front of the seat base and back underneath or within the seat base, such that excess material of the outer cushion is positioned underneath or within the seat base. The cord is connected to an end of the outer cushion at the excess material. The motor is adapted to pull the excess material underneath or within the seat base while the seat base is in a retracted position and to release the excess material while the seat base is in an extended position. At least a portion of the excess material is used to form part of an extended seat for a vehicle occupant while the seat base is in the extended position.

An actuator for a vehicle seat can be configured to prevent overstress of a shape memory alloy (SMA) wire. The actuator can include a first body member and a second body member pivotably connected to each other. The actuator can include an overstress post and an overstress contact plate operatively connected to the overstress post. Thus, movement of the overstress post causes movement of the overstress contact plate. The actuator can include an overstress contact pin. The actuator can include an SMA wire operatively connected to one of the body members and to the overstress post. When activated, the SMA wire can shrink, causing one of the body members to pivot relative to the other body member and causing the overstress contact plate to move toward the overstress contact pin. If the overstress contact plate contacts the overstress contact pin, the SMA wire can be deactivated.

An adjustable vehicle seat includes a seat base having a seat surface and a backrest having a backrest surface. In the seat base and/or in the backrest, sensors are provided that detect forces, pressures and/or movements effected by a person sitting on the vehicle seat and consequently issue a signal. A control device is provided that detects the signals issued by the sensors and actuates actuators provided in the vehicle seat to adjust the seat base and/or backrest, or components thereof, in order to adjust the vehicle seat.

A reclining seat assembly includes a seat frame, and a backrest frame supported by the seat frame for pivoting movement about a backrest pivot axis. A seat pan has a forward portion supported by the seat frame for relative longitudinal movement, for example, using a slider. The seat pan has a rearward portion that is pivotally supported along a rear seat pan axis by a lower extension of the backrest frame, such that the backrest frame reclines relative to the seat frame upon forward longitudinal movement of the rear seat pan pivot axis relative to the seat frame. A backrest recline angle adjuster on the seat frame, such as a pair of linear actuators respectively coupling the seat frame to each side of the backrest frame along an actuator pivot axis that is itself offset from the backrest pivot axis, maintains a selected position of the rear seat pan support axis relative to the seat frame to thereby achieve a desired backrest inclination.

A vehicle seating assembly includes a seatback and a seat base. The seat base is operably coupled to the seatback. The seat base includes a first suspension assembly and a second suspension assembly. The first suspension assembly includes a seat pan assembly and a seat cushion assembly. The seat cushion assembly is positioned above the seat pan assembly. The second suspension assembly includes a plurality of independent thigh supports operably coupled to a forward portion of the seat pan.

A pad is adapted to set on a seat pan included in a vehicle seat. The pad includes a cushion on the seat pan and a cushion cover on the cushion.

The present invention relates to an inbuilt seat leg support and a seat. The seat leg support is mounted in a seat. The seat includes a base frame and a cushion frame located above the base frame. A receiving space is formed between the base frame and the cushion frame. The seat leg support includes a leg support frame configured to be received in the receiving space. The leg support frame is movable and adjustable relative to the cushion frame. Movement and adjustment of the leg support frame cause the leg support frame to extend out of the receiving space to be in an extended state or to retract into the receiving space to be in a received state. According to the present invention, a receiving space for a leg support frame is reserved between a base frame and a cushion frame, and the leg support frame is disposed to be movable so that the leg support frame can be received in the receiving space when not in use. Receiving a leg support in a seat causes the present invention to be space-saving.
