The invention relates to a contouring device for a seat base, backrest, or mattress. The device comprises a substrate having a first surface and an opposing second surface, the first and second surfaces each comprising a plurality of pockets adapted to receive one or more inserts therein. Inserts of various sizes and shapes can be placed within selected pockets of the device to provide a contoured surface that suits the needs of the user of the device. For example, the device can be adapted to provide contours that encourage a user to adopt a preferred posture when seated or lying down.

The invention discloses a seat pan (20), being formed from a first thermoplastic composite material into a one-piece pan, the seat pan (20) having a weight loading portion (201), wherein at least one slot (2010) is provided in the area of the weight loading portion (201) of the seat pan (20), and covering strips (2012) are formed by overmolding on the side edges of straps (2011) separated by the slot (2010) and extending along at least a portion of the circumference of the slot (2010) so as to reinforce the straps (2011), the covering strips (2012) being made of a second thermoplastic composite material. Furthermore, the invention discloses a seat (1) comprising the above seat pan (20).

The present invention relates to a cantilever seat cushion for reducing lower back strain, including: an inner pre-cut foam; an air tight shell that surrounds the inner pre-cut foam; an outer fabric cover that surrounds the air tight shell; an air valve that adjusts an incline angle of the cantilever seat cushion by deflating or inflating the seat in which the incline angle of the cantilever seat cushion is in a range from 10 to 25 degrees.

A chair component assembly includes a support component adapted to support a portion of a seated user, and a cover including a plurality of sides that cooperate to form an interior space that receives the support component therein, the cover further including a support component receiving aperture and a flap movable between an open position where the support component may be moved from an exterior of the cover to the interior space of the cover, and a closed position where the flap covers the support component receiving aperture, and wherein the flap is secured to the support component by a quick-connect fastener.

A chair assembly includes a four-bar arrangement that includes a lower end and an upper end where the upper end is adjustable between a raised position and a lowered position, and an arm rest assembly adapted to support the arm of a seated user thereon and supported on an upper end of the four-bar arrangement, wherein the lower end of the four-bar arrangement is pivotably supported from an arm support structure for pivotable movement about an arm pivot axis, such that the upper end of the four-bar arrangement is movable between a first position and second position located laterally outward from the first position, and wherein the arm pivot axis is angularly offset from a vertical axis.

An apparatus for improving sitting posture has a pair of cushion members and a belt or strap connected to the cushion members for attaching the cushion members to a seat back at spaced locations thereon. The device is attached to a seat back so that the cushion members are positioned along or proximate respective vertical edges of the seat back, are spaced from one another and are located at substantially the same height or vertical distance from a horizontal buttocks support member attached to the seat back.

A seat cushion that provides enhanced comfort and support for a user, comprises a base surface and a plurality of air cells that are positioned on and extend generally upwardly away from the base surface. The plurality of air cells include (i) a first paired air cell having a first upper surface, the entire first upper surface being angled in a first direction relative to the base surface; and (ii) a second paired air cell having a second upper surface, the entire second upper surface being angled in a second direction relative to the base surface that is different than the first direction. The second paired air cell is positioned adjacent to the first paired air cell. Additionally, the first paired air cell and the second paired air cell cooperate to provide a substantially concave combined upper surface.

A vehicle seat includes: a cushion pad in which one or more hanging grooves into which a trim cover is inserted are formed in a sitting-person supporting surface; a wire which is provided in a bottom of the hanging groove along the hanging groove and locks the trim cover which is inserted into the hanging groove; a vibration transferring member which is buried in the cushion pad along the wire; and a vibration body which excites the vibration transferring member.

The inventive concept relates to a chair-type virtual reality controller, wherein the chair-type virtual reality controller includes a seat on which a user is seated, a base on which feet of the user seated on the seat rest, wherein a walking motion of the user is performed on the base; a rotary shaft rotatably coupled to the base such that the seat rotates relative to the base; and a control unit configured to present a VR image to the user based on a rotation motion of a body of the user seated on the seat around the rotary shaft and the walking motion of the user on the base.

An adjustable chair frame with a back and seating surfaces that flex to conform to the shape, weight and movement of an occupant is disclosed. The chair form and proportions provide for a recumbent position that disperses the weight of the occupant more evenly, thereby reducing external and internal physiological point loading. The form also provides ergonomic articulation to minimize internal physiological stresses such as neck/back vertebral compression. Eccentric connections driven by a motor assembly allow positioning adjustment of the components of the chair. Additionally, an air pump assembly may be included to automatically adjust one or more air bladders provided on the interior of the chair frame.
