A vehicle seating assembly includes a seat carrier defining a central opening. A seatback is pivotally coupled to the seat carrier. A seat flexmat is disposed in the central opening and operable between flexed and unflexed conditions. The vehicle seating assembly also includes a first thigh extension that is extendable and rotatable relative to the seat carrier and a second thigh extension that is extendable and rotatable relative to the seat carrier. The first thigh extension includes a first thigh flexmat operable between flexed and unflexed conditions. The second thigh extension includes a second thigh flexmat operable between flexed and unflexed conditions.

A track assembly includes a track, a support member, and/or a lever. The support member may be connected to the lever, and/or the lever may include a rotational axis substantially parallel to the track. The lever may rotation about the rotational axis between a first position and/or a second position. The lever may be configured to engage the track in a longitudinal direction when the lever may be in a first position. The lever may be configured to engage the track in a lateral direction when the lever may be in a second position. The lever may be configured to limit longitudinal movement of the support member along the track. The track may include a longitudinal window that may have a first edge and/or a second edge.

A pumping device for a seat of a vehicle is proposed. In the pumping device, a spring providing a restoring force to a lever bracket is directly connected to a housing without a separate component, so that the manufacturing cost is reduced and a layout size is reduced in response to removal of the component supporting the spring.

Disclosed is a vehicle seat (1) comprising a seat cushion (2) and a seat back (4), wherein the seat cushion and the seat back are comprised of: a frame structure (8) to be fixed to the vehicle body; and a seating member (10) supported by the frame structure having an elastic deformation property and a vibration damping property and allow an occupant to be seated therein, and wherein the vehicle seat satisfies the following relationship: D.sub.S/D.sub.F20, where D.sub.S denotes a deformation amount of the seating member itself in a situation where a load W is applied at a position X.sub.S of the seating member, and D.sub.F denotes a displacement of a position X.sub.F of the frame structure corresponding to the position X.sub.S, in a situation where the frame structure is fixed to the vehicle body, and the given load W is applied at the position X.sub.F.

The invention relates to a damping member (1) which has at least two engagement points (2), wherein the damping member (1) comprises at least one spring element (3), the spring elements (3) have an absorption means, the spring elements (3) have a curved shape (4), and the curved shape (4) of the spring elements (3) has a recess (4) which enables the spring elements (3) to be deformed.

Suspension systems and grounds maintenance vehicles incorporating the same are disclosed. The suspension system may include biasing elements or springs that may be adjusted to vary the preload and thus change the spring and dampening characteristics of the suspension system. In some embodiments, the system may include an adjustment mechanism that permits simultaneous adjustment of two springs via a single action. In other embodiments, features adapted to assist an operator with mounting/dismounting the vehicle are disclosed.

A cam assembly includes a pin, a first cam, a second cam, and/or a bearing. The first cam may be connected to the pin, and/or the second cam may be connected to the pin. A bearing may be configured to rotatable support the pin. The second cam may include a first portion and/or a second portion. The first portion of the second cam may be configured to contact a track in a first vertical position of the pin. The second portion of the second cam may be configured to contact said track in a second vertical position of the pin. The first portion may be vertically offset from the second portion. The first position of the pin may correspond to an unloaded state. The second vertical position of the pin may correspond to a loaded state.
