A chair includes a base having a control assembly operably supporting a seat assembly and also a back assembly for movement about a seat tilt axis and a back tilt axis, respectively. The back assembly includes a flexible sheet supported at upper / outer corners by a back support structure and hanging downwardly. The flexible sheet includes a lower portion coupled to the back support structure by a tensioner for holding the lower portion rearwardly. A vertically-adjustable lumbar mechanism is adjustably supported on the back support structure and operably engages the flexible sheet for flexing a lumbar area of the flexible sheet forwardly to provide an optimal ergonomic horizontal and vertical convex shape for postural lumbar support.

A chair includes a lower back frame, a back construction, including a back support attached to the lower back frame, a cushion assembly attached to the back support and a clip wedgingly engaged between the back support and the cushion assembly. The cushion assembly further includes an inner shell which includes two or more apertures and a hook extending downwardly and outwardly from each aperture. The clip further includes at least one angled ramp and at least one stop. The angled ramp is configured to allow the hook of the inner shell to slide through the angled ramp and the stop is configured to suspend sliding of the hook. Methods of assembling a back construction are also provided.

An exercise device having a body extension mechanism including a press plate mechanism and an articulating seat structure. The press plate mechanism is pivotally connected to a frame forwardly of the articulating seat structure, which is also connected with the frame. The press plate mechanism is operably connected with the articulating seat structure by a transfer link so that when a user actuates the press plate mechanism, the movement of a back support of the articulating seat structure is coordinated with the movement of the press plate mechanism. Resistance for the exercise device is provided by a weight stack that is operably connected with the body extension mechanism through an arrangement of pulleys so that when the user actuates the press plate mechanism a portion of the weight stack is lifted.

A seat for installation in a vehicle that is adjustable to support an occupant's thighs. The seat includes a generally-horizontal seat frame supporting a seat cushion including a front edge that at least partially extends outwardly beyond the seat frame, a seatback coupled to the seat frame for providing back support to the occupant while seated, and a seat bracket coupled to the seat frame and compatible with a floor bracket supported above a floor of a vehicle cabin for coupling the seat to the vehicle. The seat further includes an adjustable thigh support adjacent to a front portion of the seat cushion. The thigh support includes a spool coupled to the seat frame that can be adjusted relative to the seat frame between a retracted position and an extended position, wherein the front edge of the seat cushion is at least partially wrapped around the spool while the spool is in the retracted position, and the front edge of the seat cushion is at least partially unwrapped from around the spool while the spool is in the extended position.

In order to provide a walking assistance device capable of favorably providing an assisting force for maintaining the upright posture while reducing the sense of pressure when worn by the user, a hip support member (1) of the walking assisting device, which comprises an assisting force generator (hip joint actuator 10) disposed at least on a side of a hip joint to provide an assisting force to a movement of a lower limb, is provided with: a back support (4) equipped with pads (18, 19, 20) for respectively abutting an intermediate portion between right and left erector spinae muscles, lateral outer sides of the spinae muscles and right and left iliac crests; and a belt (5) connected to the back support for tightening a lower part of the rectus abdominis muscle. In this way, a supporting force can be provided to the lumbar vertebrae to steadily keep the upright posture while reducing a resistance to a bending movement of the waist caused by the support member. Further, the drive torque from the assisting force generator can be supported by the whole hip portion and this can contribute to preventing inadvertent move of the support member.

A string arrangement for a detachment type waist-protecting belt to hold the vertebra region of a vertebra related patient is provided. The string arrangement enables a separate fastening of the upper portion and lower portion of the belt to form a saddle like shape that fits the contour of the waist of an individual patient dynamically with or without the extra support of a frame. The waist-protecting belt can also be connected to a back supporting frame, which is comprised of two plastic plates, via two guiding nuts, fixed on the center of the exterior side of the inner-half of the rim of each solid plastic plate, guided through the two narrow and long holes found on the wider portions of the belt, and held in place by two wide head bolts which screw on to the nuts. Then the upper portion and lower portion of the frame is adjusted separately by the movement of the upper and lower portion of the belt.

A seat back structure of vehicle seat which is reduced in thickness and yet deformable to provide a deep cushiony touch to a back of passenger. According thereto, an elastic back support element and a back board element are respectively provided in one and another sides of seat back, and a movable connection element is provided so as to allow displacement of the back board element from a home position, while allowing the elastic back support element to be resiliently warped. The back board element is normally biased by a biasing element of the home position. A stopper element is defined in the seat back for preventing movement of the back board element from the home position to the elastic back support element. The back board element per se may be formed by a plurality of plate elements connected movably with one another.

The office gym exercise kit is a portable exercise kit that provides for a number of exercises to be performed by a user, including arm, leg and back exercises. The kit components are capable of attaching about a chair post and a chair back support to provide the exercises for the user. A flexible body is wrapped around the post and under the base of the chair then secured such that the flexible body remains in place around the chair post. A flexible band is wrapped around the chair back support. Both the flexible body and flexible band have retainers attached thereon. Several elastic straps are included in the kit. The elastic straps may be fastened to the flexible body and flexible band by latching onto the retainers. The user then exercises by extending the elastic straps with arms, legs or the like.

Systems and techniques are disclosed for a planar seating apparatus having a seat support in a first plane, a back support in a second plane and coupled to the seat support, and a plurality of side supports coupled to the back support. The plurality of side supports are adjustable and capable of folding, as is the back support, to provide a compact and easily transportable and storable device.

An acoustic structure of seat back in which speaker units are provided in a padding of the seat back. The padding includes: a frontal backrest surface area which is recessed backwardly of the seat back; and securing holes formed in that frontal backrest surface area. An enclosure of each speaker unit, in which each speaker is securely accommodated, is secured in each of the securing holes. A sound-conductive cushion element is juxtaposed on the foregoing recessed frontal backrest surface area of padding so as to lie on a frontal side of each of the speaker units. The sound-conductive cushion element may be of a network structure to not only provide an improved back support touch, but also achieve an improved conductivity of sounds from the speaker units to a user's back portion. Those padding and sound-conductive cushion element are covered with a trim cover assembly.

An self adjusting back support assembly for a seat is provided comprising a plurality of pivotally adjustable back support members juxtaposed one another such that each of said back support members is able to pivot about an axis contained wholly within an adjacent back support member allowing the back support assembly to adopt a serpentine contour substantially following a contour of an occupant's back.
