There is provided a vehicle seat, including: a first support configuration section that includes a first cover; a second support configuration section that is disposed adjacent to the first support configuration section, and that includes a second cover; a double hinge that couples the first support configuration section and the second support configuration section together; an intermediate shutter that is disposed along a space between the first cover and the second cover; a first shutter that blocks a gap formed between the first cover and the intermediate shutter accompanying relative displacement between the first support configuration section and the second support configuration section; and a second shutter that blocks a gap formed between the second cover and the intermediate shutter accompanying relative displacement between the first support configuration section and the second support configuration section.

A work vehicle includes a driver's seat attached to a seat base, a support shaft attached to the seat base and extending in a vehicle body transverse direction, the support shaft pivotably connecting the seat base with the vehicle body frame, and an isolator mounted on the support shaft to absorb only vibration in a vehicle body front/rear direction.

Various embodiments of the present technology may comprise a method and apparatus for a space-saving suspension system. In various embodiments, the apparatus may comprise a fine suspension device, a coarse suspension device, and a mechanical assembly. In various embodiments, the fine suspension device is arranged at an angle greater than zero degrees from the z-axis. In various embodiments, the mechanical assembly is coupled to the fine suspension device and a payload, such that when a force is exerted on the mechanical assembly by the payload, an applied force is transmitted to the fine suspension device.

An isolator performance data logging system comprising a displacement unit for measuring a displacement of the isolator. the displacement unit comprises a displacement sensor housing fixable relative to a mitigated end of the isolator, a target fixable relative to an unmitigated end of the isolator. A displacement sensor is located within the displacement sensor housing for measuring a displacement of the target relative to the displacement sensor. A first accelerometer unit is fixable relative to the mitigated end of the isolator. A second accelerometer unit is fixable relative to the unmitigated end of the isolator.

Provided is a vehicle seat for use with an occupant classification system (OCS). The seat comprises: a seat base including a seat base support, and a cushion pan mounted on the seat base support and forwardly moveable on the support to extend the seat base. The seat further comprises an intermediate layer fixed with respect to the seat base support and adapted for fastening to a component of the OCS so that when the seat base is extended by the cushion pan moving forward with respect to the seat base support, the intermediate layer does not move forward with the cushion pan but remains substantially stationary. The relationship between the various OCS components can therefore be maintained irrespective of the extension of the seat base.

A seat suspension includes a frame fixedly securable to a structure. A suspension assembly is operably connected to the frame. A seat support is adapted to receive a seat, and the seat support is operably connected to the suspension assembly. The suspension assembly includes a first elongate suspension bar slidably disposed on a pivot surface. The first suspension bar has a first end slidingly secured to the seat support and a second opposed end secured to a shock compensating device. The suspension bar is translatable relative to the pivot surface, wherein moving the suspension bar changes the shock compensation of the suspension assembly.

A seat assembly for supporting an occupant of a vehicle includes a cushion and a suspension. The cushion has a first surface and a second surface. The first surface is configured to engage the occupant. The second surface is disposed opposite the first surface. The suspension includes a first portion and a second portion. The first portion includes a third surface. The third surface engages the second surface of the cushion. The second portion includes a fourth surface. The fourth surface defines a first depression. The first depression opens toward the cushion. The first depression is configured to receive a portion of the cushion when the occupant exerts a load on the cushion.

Various embodiments of the present technology may comprise a method and apparatus for a space-saving suspension system. In various embodiments, the apparatus may comprise a fine suspension device, a coarse suspension device, and a mechanical assembly. In various embodiments, the fine suspension device is arranged at an angle greater than zero degrees from the z-axis. In various embodiments, the mechanical assembly is coupled to the fine suspension device and a payload, such that when a force is exerted on the mechanical assembly by the payload, an applied force is transmitted to the fine suspension device.

To make it possible to improve seated person's posture stability with respect to input vibration, and more improve a vibration absorption characteristic or an impact absorption characteristic caused by impact vibration as compared with conventional ones. A suspension mechanism 1 has a structure in which two suspension units 100, 200 which support a movable support part 140 and a seat support part 240 through link mechanisms 110, 120 respectively are arranged in two upper and lower stages, and a configuration such that, when the movable support part 140 and the seat support part 240 move up and down relatively in response to input vibration, the two link mechanisms 110, 210 supporting the respective parts are operated to rotate in opposite directions to each other. Therefore, a position of a hip point of a person seated on a seat supported by the seat support part 240 is displaced in an approximately vertical trajectory, which reduces forward and backward swinging and stabilizes a seating posture, resulting in good ride comfort, as compared with a case of one link mechanism.

Vehicle seat having a pitching spring unit, a vehicle seat upper part and a vehicle seat lower part of the vehicle seat being connected such that they can be moved relative to one another by means of a scissor frame arrangement, comprising a first scissor arm and a second scissor arm which cross in a first region as viewed in a vehicle seat width direction, the pitching spring unit comprising a spring element carrier and a spring element, the spring element being connected on one side to the vehicle seat upper part, the vehicle seat lower part or the scissor arms and on the other side to the spring element carrier which is connected to the first scissor arm such that it can be rotated about a second rotational axis and to the second scissor arm such that it can be rotated about a third rotational axis.
