A load-detecting device 1 includes a load detection sensor unit SU and a base 2 on which the load detection sensor unit SU is mounted, and the load detection sensor unit SU includes an upper surface 47S configured to be pressed by a seat cushion SC, a first electrode 52, and a second electrode 62. The upper surface 47S moves with respect to the mount surface 21S such that an angle of the upper surface 47S with respect to the mount surface 21S changes.

A seat assembly is provided having a seat bottom and a seat back mounted adjacent the seat bottom. A cushion is disposed on at least one of the seat bottom and seat back and defines a seating surface. The seating surface has a plurality of regions. A controller is in communication with the cushion and is programmed to independently vary a stiffness of each of the regions along the seating surface.

There is provided a cushion spring including: a pair of formed wires bridged to a seat cushion frame in a seat front-rear direction and are arranged side by side in a seat width direction; and a resin member joined to the pair of formed wires. The resin member includes a rear connecting portion and a pair of deflection restricting portions, the rear connecting portion extending to connect between a side wire and a center wire and between the center wires in the seat width direction in a region on a seat rear side of an ischium supporting portion of the pair of formed wires that supports an ischium of the seated occupant via a seat cushion pad, the pair of deflection restricting portions extending from the rear connecting portion to connect all crank-shaped portions in the seat front-rear direction.

A method of packaging a convertible couch into a box includes forming a frame assembly. Forming the frame assembly includes coupling a plurality of arms, a first seat portion, a second seat portion, a first back portion, and a second back portion together. A plurality of pillows and at least one back cushion are positioned within the frame assembly. The frame assembly is positioned into the box after assembly and a divider is placed on top of the frame assembly. A first mattress roll is formed and then a second mattress roll is formed. The first mattress roll and the second mattress roll are placed on the divider in the box and the box is closed and sealed.

Beam mounted chair assemblies may include at least two standards supported on a floor, a beam secured to, and supported by, the standards, and a plurality of chair assemblies secured to, and supported by, the beam. Chair assemblies may be secured to a beam via associated chair brackets. Chair brackets may include chair seat pivots that pivotally secure a chair seat in proximity to a chair back such that the chair seat may pivot between an up and a down position. Chair brackets and standards may be secured to a beam such that the chair brackets and standards may be linearly positioned along a full length of the beam without interfering with one another.

A vehicle seat that can reduce manufacturing costs while increasing assembling rigidity of an elastic spring for supporting an occupant is described. A vehicle seat includes an elastic spring bridged between a front frame and a rear frame to support an occupant. A hook member is attached to a rear end portion of the elastic spring to be hooked to the rear frame. The hook member includes a hook body extending along an outer periphery of the rear frame and a projection projecting from a front edge of the hook body toward the rear frame and formed to have a width smaller than a width of the hook body. A through-hole is formed in a portion of the hook body, which is opposed to the projection. The through-hole has a width larger than a width of the projection and a length larger than a projecting length of the projection.
