The operation in a closing direction and the operation in an opening direction of a storage rack are performed efficiently with small force. Fixed frames and a storage rack are connected by link mechanisms, and the link mechanism includes fixed-side links linked to the fixed frame and movable-side links linked to the storage rack. When a position of one ends of the movable-side links is located closer to one ends of the fixed-side links than a balanced point, the elastic member biases the storage rack in an open-position direction. In the open position, since the elastic member biases the storage rack in the opening direction, an open state is maintained as long as the position of the one ends of the movable-side links does not return to the change point position. Accordingly, the open position can be held by a simple structure without using electric power.

A vehicle seat back may include an integrated suspension structure including a suspension wire and suspension mounting guides coupled to both sides of the suspension wire; and a seat back pad foamed for integrating with the integrated suspension structure in a state in which the integrated suspension structure is inserted into a mold for seat back pad formation.

A generally vertical pillar extends between a floor and a ceiling of a vehicle chassis and carries a seat. A damper is secured between an attachment point on the pillar and an attachment point vertically offset therefrom on the vehicle chassis. This damper comprises a plurality of C-shaped springs each attached at one of the attachment points to the pillar and extending therefrom at an angle of 45° relative to the pillar and an opposite end attached at the other attachment point to the chassis and extending therefrom at an angle of 45° relative to the pillar. The springs each are elastically deformable and form force absorbers that return to a starting shape after elastic deformation. Each C-shaped spring defines a gap open at an acute angle to the vertical and that varies in dimension on deformation of the respective spring.

A support member may be configured for selective connection with and removal from track assemblies. A support member may include a body and a rolling member rotatably connected to the body to facilitate movement of the support member along a track. The rolling member may include a grooved configuration to limit movement of the support member relative to said track in a Y-direction. The rolling member may include a groove configured to engage a protrusion or ridge of said track. The rolling member may include a first portion and a second portion separated in an axial direction by the groove.

A utility vehicle includes a frame, a first ground-engaging element coupled to a first portion of the frame, a second ground-engaging element coupled to a second portion of the frame, an operator platform supported by the frame, and a suspension system coupled between the operator platform and the frame to accommodate motion of the frame relative to the operator platform. The suspension system includes a first linkage assembly coupled to the operator platform and operable to accommodate motion of the second portion of the frame relative to the operator platform and a second linkage assembly having a first end coupled to the frame to secure the suspension system to the frame and a second end coupled to the first linkage assembly. The second linkage assembly being operable independent of the first linkage assembly to accommodate motion of the first portion of the frame relative to the operator platform.

A vehicle seat includes a first seat component such as a seat pan or seat frame, and a second seat component such as a seat back. The first seat component is rotatably coupled to the second seat component by a rotatable coupling, and a laterally oriented vibration isolator is positioned between the first seat component and the second seat component at the rotatable coupling. Transmission of vibration from the first seat component to the second seat component through the rotatable coupling is suppressed by the vibration isolator. In some cases, the vibration isolator is a quazi-zero-stiffness (QZS) isolator.

An adequate mechanical stiffness and strength are afforded to a tumble seat or a vehicle seat having a latch mechanism provided in a rear end of the seat cushion. A cushion frame (F1) of the seat includes a side frame (5) extending in a fore and aft direction, and the side frame includes a first member (10) comprising a channel member having an open side facing sideways and a second member (11) attached to the first member so as to form a closed cross section jointly with the first member, and extending downward further than the first member. A latch mechanism is positioned under the first member and attached to the second member.

Systems and methods for limiting transmission of vibrations and forces causing vibrations from one element to another are provided. A vibration isolator may include a compressible inner member and an outer member compressible with the inner member. The outer member may be positioned at least partially around the inner member to provide lateral support to the inner member. The outer member may maintain a consistent diameter and compression force when in a compressed state. The outer member may include a tube with a zero or near-zero Poisson's ratio.
