The invention relates to a vehicle seat comprising a seat part and a backrest part, the seat part being configured shell-shaped on the lower face, at least one front end of the seat part being displaceable forwards and upwards in a combined manner and the inclination of the seat part being adjustable by means of an adjustment movement of the seat part with respect to a seat support shell arranged below the seat part.

System and methods for nullifying one or more of lateral and longitudinal acceleration forces experienced by an occupant of a vehicle in a seated or standing position while the vehicle is traveling along a travel plane, including: a chassis structure; an occupant cell one of coupled to and defined by the chassis structure; and one or more of a seat assembly configured to receive the occupant in a seated position and a standing platform assembly configured to receive the occupant in a standing position disposed within the occupant cell; wherein the one or more of the seat assembly and the standing platform assembly is/are configured to pivot one or more of: laterally at a longitudinal pivot point with respect to the chassis and travel plane; and longitudinally at a transverse pivot point with respect to the chassis and travel plane.

A target support device includes a bottom configured to be fixed to a floor of a vehicle and have a concave curved surface and three or more support members disposed on an upper side of the bottom and configured to come into contact with a convex curved surface formed on a lower surface of a target to support the target and have a surface which is formed as a curved surface.

A vehicle seat includes a movable portion, a first spring, a second spring, and a preloading device. The first spring is capable of exerting an elastic force to displace the movable portion, which is displaced in a first direction, toward the neutral position. The second spring is capable of exerting an elastic force to displace the movable portion, which is displaced in a second direction, toward the neutral position. The preloading device is capable varying at least one of an elastic force applied by the first spring to the movable portion placed in the neutral position or an elastic force applied by the second spring to the movable portion placed in the neutral position.

Described are passenger seats having a seat frame and a seat bottom slidingly and pivotally attached to the seat frame that, when the passenger seats are reclined, are configured to articulate forward from an upright configuration of the passenger seat to a second seat position corresponding to a reclined configuration of the passenger seat. The seat bottom can include an aft articulating mechanism that defines a declining first path in an aft-to-forward direction to cause the aft end of the seat bottom to drop when the seat bottom articulates forward; and a forward articulating mechanism connected with the seat bottom near a forward end of the seat bottom that defines a second path shaped to cause the forward end of the seat bottom to move upward when the seat bottom articulates forward, such that the seat bottom tilts aft in response to articulating forward when the passenger seat is reclined.

A vehicle seat sliding apparatus includes an upper rail that supports a seat at an upper side, a lower rail that supports the upper rail to be relatively movable manner in a longitudinal direction of the upper rail, and a lock mechanism configured to restrain the upper rail from moving relative to the lower rail. The upper rail includes two side walls that are opposed in a width direction of the upper rail and an upper wall that connects the two side walls. The upper wall has a plurality of seat fasteners. The upper rail has at least one hole between a longitudinal end of the upper rail and one of the seat fasteners closest to the longitudinal end. The hole is a cutout formed in each of the two side walls and the upper wall.

A working machine includes an operator's seat, a seat base supporting the operator's seat, and a slide rail for adjustment of a position of the operator's seat, the slide rail being located between the seat base and the operator's seat, in which the seat base includes a rail mount for attachment of the slide rail, the rail mount having a downward convex curve which is curved to deviate from the slide rail with increasing distance from each of opposite ends of the rail mount in a longitudinal direction of the slide rail and with decreasing distance to a center of the rail mount in the longitudinal direction.

A vehicle seating assembly comprising a base assembly including an inner base shell and an outer base shell and defining a recess, a shell assembly operably coupled to the base assembly, wherein a bottom of the shell assembly nests within the recess, at least one armrest integrally formed with the shell assembly, and at least one headrest wing integrally formed with the shell assembly.

A seating assembly comprising a shell assembly, a base assembly operably coupled to the shell assembly, and a control assembly including a handle. The control assembly comprises a spindle gear positioned within the base assembly, a gear plate disposed in the shell assembly proximate the spindle gear, a locking key configured to simultaneously engage the spindle gear and the gear plate, a locking leaf spring configured to bias the locking key into engagement with the spindle gear and the gear plate, and an actuator configured to withdraw the locking key from engagement with one of the gear plate and spindle gear and subsequently withdraw the locking key from engagement with the other of the gear plate and spindle gear.

A vehicle seating assembly comprising a base assembly including an inner base shell and an outer base shell and defining a recess, a shell assembly operably coupled to the base assembly, wherein a bottom of the shell assembly nests within the recess, at least one armrest integrally formed with the shell assembly, and at least one headrest wing integrally formed with the shell assembly.
