Provided is a vehicle seat having a variable cushion length. The vehicle seat includes: a front panel of metal arranged on a front-end side of a seat cushion to form a frame of the seat cushion; a sliding device allowing a movable portion to be displaceable and including a sliding member of resin displaceable relative to the front panel in seat front-rear directions; and a bracket of metal that is coupled to the front panel in a manner displaceable relative to the front panel in the seat front-rear directions and that is displaced integrally with the sliding member, the bracket transmitting a load acting on the movable portion to the front panel.

A transportation system is disclosed. The transportation system includes a vehicle, a plurality of seating assemblies positioned within a passenger compartment of the vehicle and defining an arrangement, a plurality of actuators that effect movement of various components of the plurality of seating assemblies, a plurality of sensors, and a controller. Specific examples of pre-set or pre-programmed arrangements are disclosed, as well as the ability to customize the arrangement. Additionally, exemplary methods are disclosed that illustrate transitions between a variety of the pre-set or pre-programmed arrangements.

A conveyance seat capable of suppressing wrinkles or saggings from occurring on a surface of a seat main body is provided. A conveyance seat S includes a seat back and a movable body which is attached inside the seat back, is disposed at an outer position in relation to a center portion of the seat back, and is operated so that a side portion of the seat back protrudes toward a seated occupant side (seat front side). The movable body is disposed on a back surface of a cushion material in the side portion. An end portion (rear end portion) on the side opposite to the seated occupant side of the movable body is disposed on the seated occupant side (seat front side) in relation to a seating surface of the center portion of the seat back.

A system for a boat can include a pair of seat rails configured to simultaneously couple the seat to a floor of the boat in any one of multiple positions in a longitudinal direction of the seat rails, the seat rails being parallel to each other when the seat is coupled to the floor.

An assembly includes a seat bottom including a panel pivotable from a first position to a second position. The assembly includes a track supported by the seat bottom. The assembly includes a spring in the track and urging the panel toward the second position. The assembly includes a pyrotechnic actuator maintaining the spring in compression and actuatable to release the spring.

A vehicle seat is provided that has a seat part frame and a seat back adjustment with a seat depth adjustment element, where the seat back adjustment element can be displaced relative to the seat part frame, where a locking device locks a displacement of the seat depth adjustment element relative to the seat part frame by engaging at least one recess of the seat part frame, where the locking device includes a locking unit which has a first end on the seat depth adjustment element, and a second end, which can be deflected, the second end engaging the locking element in the recess in a non-deflected position and the locking element being separated from the recess in a deflected position and a sliding carriage element that deflects the second end of the locking unit when the sliding carriage element is displaced relative to the locking unit.

A seat cushion includes a plurality of inflatable cells, a pumping mechanism, and a manifold or valve system fluidly between the pumping mechanism and the inflatable cells. The manifold or the valve system, which may include a clutch and a motor, connect the pumping mechanism with the inflatable cells such that a plurality of zones are created. A valve assembly can include a plurality of valves and is adjustable among at least three valve configurations to vary fluid connections to the inflatable cells to produce rearwardly advancing waves. The pumping action produced by the inflation and deflation of the inflatable cells assists in pumping blood in a user's legs back toward the heart.

A child safety seat includes a seat shell for receiving a child, an extension member, an extension locking mechanism operable to lock the extension member with respect to the seat shell, and an anti-rebound part. The anti-rebound part can be installed on the extension member or the seat shell. The child safety seat is installable on a vehicle seat in a rear facing position with the anti-rebound part extending at an angle above the extension member and adjacent to a seatback of the vehicle seat.

Clutch-based adjustment mechanism for motorized multi-way seat adjustment An adjustment mechanism comprises multiple screw shafts (111, 112, 113) and a motor (150) for driving the screw shafts. Further, the adjustment mechanism comprises a clutch mechanism (160) for selectively engaging the motor (150) with one or more of the screw shafts (111, 112, 113). A rotation of one or more of the screw shafts (111, 12, 113) caused by the motor (150) translates into adjustment of the seat according to a first degree of freedom. A rotation of one or more others of the screw shafts (111, 12, 113) caused by the motor (150) translates into adjustment of the seat according to a second degree of freedom.
