A chair having an articulating backrest that deforms when reclined to support an occupant's head or shoulders. A backrest assembly includes a mesh insert secured to a frame, which includes an upper frame section and a lower frame section interconnected by a pair of articulated joints. A push arm pivotally connects to the chair's seat assembly and to the backrest's upper frame section. As the chair reclines, the push arm restricts the angular movement of the upper frame section relative to a floor. The lower frame section moves forward relative to the upper frame section. Consequently, an angle formed between the lower frame section and the upper frame section decreases during recline, thereby supporting the chair occupant's head or shoulders. Optionally, a tensioning member may connect the mesh insert to the push arm to offset any loss of tension caused by the deformation of the frame during reclined.

The invention is an improved utility bedding product for use on beds or reclining chairs, particularly airplane seats. The inventive product is a multi-layered, lie-flat mattress pad that increases the comfort of passengers by providing a soft resting surface made of materials that permit the flow of air through the mattress pad. In preferred embodiments the mattress pad includes a pocket so the pad may be folded or rolled up and secured in a compact configuration for use as a pillow and for ease of transport.

A vehicle seat is provided herein. The vehicle seat includes a cushion disposed within a seating member having at least one inflatable first bladder for selectively adjusting the firmness of the cushion. An inflatable second bladder is separated from a support surface of the seating member by the first bladder and fluidly connected to the first bladder. A vehicle seat hip pivot point is maintained when adjusting the firmness of the cushion by increasing the pressure in the second bladder when the pressure in the first bladder is selectively decreased, and by decreasing the pressure in the second bladder when the pressure in the first bladder is selectively increased.

A lumbar support cushion can include a ridged section, right and left protruding side supports, top right and top left protrusions, and a top cutout located between the top right and top left protrusions, which can allow a person sitting against the cushion to experience increased support on the person's lower back. The features of the cushion may promote a healthy sitting posture, proper spine alignment, and may reduce or prevent pain in the lower back. Also disclosed is a method for configuring a support contour of a cushion.

A chair assembly includes a base assembly, a seat assembly having a pair of side edges and a fore-to-aft extending longitudinal centerline, a back assembly movable between upright and reclined positions, and an arm assembly including an arm base extending from a first location between the side edges to a second location laterally outward of one of the side edges, wherein the arm base extends at an acute angle with respect to the longitudinal centerline and at an upward angle from the first location toward the second location, a support assembly supported by and extending upwardly from the arm base, and an armrest supported by the support assembly that is adjustable to support the armrest between a plurality of selected vertical positions, wherein the arm assembly and back assembly move at a different rate from one another as the back assembly is moved between the upright and reclined positions.

Disclosed is a waist support structure of a seat back. The seat back includes a first frame, a second frame coupled to the first frame, and a net member mounted between the first and second frames. The second frame includes a mounting brace mounted thereto and the mounting brace include a waist support coupling section that is connectable with a waist support. The waist support includes a support portion including a rigid plate and a connection portion. The support portion includes a barrel mounted thereto and extending toward the connection portion. The connection portion includes a projection peg mounted thereto and extending toward the support portion to correspond to the barrel. An elastic element has an end fit to the projection peg of the connection portion and an opposite end fit in the barrel of the support portion so as to interface between the connection portion and the support portion.

A furniture assembly may include a seat bottom, a seatback, and a lumbar adjustment assembly. The seatback is disposed adjacent the seat bottom and includes a seatback frame. The lumbar adjustment assembly may be mounted to the seatback frame and may include a rail, a threaded rod disposed within the rail, a first slider block slidably engaging the rail, a second slider block slidably engaging the rail, a lumbar pad, and links connecting the lumbar pad to the first and second slider blocks. The threaded rod may include a first threaded section having threads with a first handedness and a second threaded section having threads with a second handedness that is opposite the first handedness. The first slider block may threadably engage the first threaded section. The second slider block may threadably engage the second threaded section. One or more massaging units may be mounted to the lumbar pad.

A thoracic support for a seatback of a seat is provided. The thoracic support includes a center portion extending in an upright direction and adapted to be positioned adjacent the seatback to align adjacent a thoracic region a user's spine. The center portion is formed of a first foam material having a first hardness. A pair of side portions each disposed adjacent to and are connected with the center portion. The side portions are formed of a second foam material having a second hardness. The first hardness is greater than the second hardness so that the center portion provides support to at least a portion of the thoracic region of the user's spine.
