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 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.

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.

A seat for a vehicle includes a seat back frame, a first elastic member, and a second elastic member. The seat back frame includes a main frame and a sub-frame. The first elastic member and the second elastic member are configured to support the sub-frame such that the sub-frame is rotatable in a width direction of the seat and are mounted between the main frame and upper end portions of the sub-frame on both sides in the width direction of the seat. Each of the first elastic member and the second elastic member has a limit of elongation and has a characteristic in which a load that is applied to the sub-frame in a rear direction of the seat acts as tension to generate a reaction force due to the limit of elongation and does not generate the reaction force in the width direction of the seat.

A seating system for a vehicle is disclosed. The seating system includes a support surface having a surface contour formed by first springs having fixed stiffness values, a frame, and second springs having adjustable stiffness values coupling the support surface and the frame. The first springs and the second springs together control motion of the support surface in relation to motion of the frame.

A seat support structure including an elastomeric panel. The elastomeric panel positions and supports a seated occupant. The panel is constrained on a forward side and a rearward side.

Described herein is a shock mitigation apparatus. The shock mitigation apparatus may be utilized in a marine environment, able to absorb shocks transmitted to a seat system from a structure to which the seat is affixed. The shock mitigation apparatus includes at least one leaf spring wherein the leaf spring is cantilevered at one end and pivoted at a distal end thereof, and wherein the pivoted end is free to articulate upon flexure of the leaf spring.

The present invention relates to a spring member mounting structure, which is a structure for mounting a spring member on a cushion frame connecting side frames by use of a rear pipe. The spring member has rear clipping portions engaged with the rear pipe. Cover members, which are provided at seat central sides of connecting portions of the side frames and the rear pipe, have extension portions extending toward the seat central sides. The rear clipping portions abut on ends of the seat central sides of the extension portions, and are mounted to the rear pipe by width direction positioning of the spring member.

The disclosure relates to a spring unit and a method for changing a spring constant of a spring arrangement in a spring unit. The spring unit comprises a first attachment arrangement, a second attachment arrangement and a spring arrangement. The spring arrangement comprises a first flexible member attached to and extending between the first attachment arrangement and the second attachment arrangement. The first attachment arrangement is fixedly attached to a support structure and the second attachment arrangement is arranged to move a first distance essentially vertically in response to a load being exerted on the second attachment arrangement. The spring arrangement comprises a first engagement element arranged to cause a change in a spring constant of the first flexible member, such that the spring constant of the first flexible member increases after the second attachment arrangement has moved a part of the first distance.
