A spring-based seat diaphragm may include at least one support diaphragm component. The at least one support diaphragm component may be transversely coupled to the first structural beam and the second structural beam. The spring-based seat diaphragm may include at least one spring. The at least one spring may be proximate to the at least one support diaphragm component. The at least one spring may be parallel to or positioned transverse to the at least one support diaphragm component between the first primary spreader and the second primary spreader. The at least one spring may include a plurality of bends configured to distribute user weight applied to a cushion installed on the aircraft seat over the spring-based seat diaphragm. The spring-based seat diaphragm may be configured to support an aft portion of the cushion. The first structural beam may be configured to support a forward portion of the cushion.

Disclosed is a fastening structure for a seating foam, comprising a foam and a reinforcement fabric, and characterized in that the fastening structure is directly provided at a reinforcement fabric at a location corresponding to a fastening position, and is connected to the reinforcement fabric. The fastening structure of the present invention simultaneously meets two functional requirements of a foam, namely reinforcement of a side B of the foam and fastening of an exterior side A of the foam. The novel fastening structure of the present invention saves space, is thin and light, enhances the strength of the foam against a pull-out force, and optimizes a foam production process.

A modular seat assembly includes a seat frame, a modular seat component for engaging the seat frame including a mounting bracket, a cable routed towards the frame and engaged with the mounting bracket, and a cable tensioning system. The cable tensioning system is configured to tighten the cable into a tensioned state and release the cable into a slacked state. In the tensioned state, the modular seat component is secured to the seat frame via engagement of the cable with the mounting bracket, and in the slacked state, the modular seat component is releasable from the cable via disengagement of the cable from the respective mounting bracket.

A vehicle seat and frame thereof which minimize the size of an attachment mechanism of a support structure for supporting the back of a seated person are provided. A seat frame has side frames positioned at right and left sides of a seat back frame and extending in an up to down direction. The side frame has a side portion extending along a side portion of the seat, a rear portion projecting from a rear end of the side portion to an inner side of the seat, and a support member spanned between the right and left side frames, and receives a load of the seated person. The support member has a connecting portion for connecting to the side frame and is attached to the rear portion of the side frame in a state where the positional relationship between the connecting portion and the side frame is fixed.

The present disclosure relates to a seat that may have a support structure and a pad having a support wire attachable to the support structure. A retainer may be provided which is fixed at one end through an opening in the support structure and at the opposite end onto the support wire. The retainer may have a mounting member to fix through the opening and a hook to catch the support wire, the mounting member having a use position and a mounting position that is inclined relative to the use position. The mounting member and the hook may be joined by a spacer bar.

A spring-based seat diaphragm may include at least one support diaphragm component. The at least one support diaphragm component may be transversely coupled to the first structural beam and the second structural beam. The spring-based seat diaphragm may include at least one spring. The at least one spring may be proximate to the at least one support diaphragm component. The at least one spring may be parallel to or positioned transverse to the at least one support diaphragm component between the first primary spreader and the second primary spreader. The at least one spring may include a plurality of bends configured to distribute user weight applied to a cushion installed on the aircraft seat over the spring-based seat diaphragm. The spring-based seat diaphragm may be configured to support an aft portion of the cushion. The first structural beam may be configured to support a forward portion of the cushion.

Provided is a vehicle seat that allows engagement holes for engaging an end part of the skin member to be provided without burdening the seat frame design. The seat cushion of the vehicle seat includes a frame structure, a support member supported by the frame structure within the frame structure to resiliently support an occupant, a pad provided on a proximal side of the frame structure and the support member, and a skin member covering the pad. The support member is provided with plurality of engagement portions engaging end parts of the skin member.

A modular seat assembly includes a seat frame, a modular seat component for engaging the seat frame including a mounting bracket, a cable routed towards the frame and engaged with the mounting bracket, and a cable tensioning system. The cable tensioning system is configured to tighten the cable into a tensioned state and release the cable into a slacked state. In the tensioned state, the modular seat component is secured to the seat frame via engagement of the cable with the mounting bracket, and in the slacked state, the modular seat component is releasable from the cable via disengagement of the cable from the respective mounting bracket.

A spring-based seat diaphragm may include at least one support diaphragm component. The at least one support diaphragm component may be transversely coupled to the first structural beam and the second structural beam. The spring-based seat diaphragm may include at least one spring. The at least one spring may be proximate to the at least one support diaphragm component. The at least one spring may be parallel to or positioned transverse to the at least one support diaphragm component between the first primary spreader and the second primary spreader. The at least one spring may include a plurality of bends configured to distribute user weight applied to a cushion installed on the aircraft seat over the spring-based seat diaphragm.
