A support unit for use on an article of furniture includes an adjustable support structure displacably mountable to the article of furniture and a cushion member carried by the support structure. The support structure is configured to be arranged in a first orientation relative to the article of furniture for enabling the cushion member to adopt a first position relative to the article of furniture and in a second orientation (46) relative to the article of furniture for enabling the cushion member to adopt a second position relative to the article of furniture.

The present application relates to a sofa backrest adjusting apparatus with integrated headrest and lumbar cushion, which comprises a frame body arranged in a sofa cover, wherein a support rod is arranged in the middle of the frame body, a bearing support frame is arranged on the support rod, and a headrest driving mechanism and a lumbar cushion driving mechanism are arranged on the bearing support frame; the headrest driving mechanism comprises a first power module and a first transmission lead screw, the lumbar cushion driving mechanism comprises a second power module and a second transmission lead screw. According to the present application, when the first transmission lead screw and the second transmission lead screw are broken, only the second transmission lead screw needs to be replaced, so that the maintenance cost of the electric sofa can be reduced.

A seating structure includes a base, a seat supported by the base, and a backrest having a frame and a suspension material supported by the frame. The frame includes an upper end and a lower end opposite the upper end. The seating structure also includes an upper thoracic support assembly supported by the frame adjacent the upper end. The upper thoracic support assembly including a thoracic support pad positioned between the frame and the suspension material. The thoracic support pad configured to engage the suspension material to support an upper thoracic region of a user.

A rebounding device includes a front member, a rear member, and a junction member releasably coupling the front member and the rear member is disclosed. The junction member enables the front member and the rear member move between a collapsed position and an expanded position, and the front member is movable relative to the rear member during a rocking motion when the junction member is in the expanded position. In one embodiment, the junction member comprises a ratchet gear, a spring-loaded pawl configured to engage the ratchet gear and prevent rotation thereof, and a torsion spring. Application of pressure by a user against the front member causes the front member to move toward the rear member, thereby loading the torsion spring. Removal of the pressure against the front member causes the torsion spring to unload, thereby biasing the front member away from the rear member.

A head restraint has a flexible tension strap, a forehead band and a shaped cushioning wedge member connected between the strap and the forehead band. The tension strap anchors the lower edge of the wedge member which acts as a fulcrum and the wedge member comprises structural integrity to be sufficiently rigid to act as a load arm to apply rearward load force on the forehead band against effort force applied against the front of the wedge member by the user's neck.

The invention is directed to a portable head support designed to fit in the interior of a carry-on article carried by a passenger. The device provides head support for those who prefer sleeping in a face-down position and comprises a base and a head support connected along at least one of their abutting edges by a mechanism which permits the angle between the base and head support to be adjusted by the user.

A headrest device and a chair having the same are provided. The headrest device includes a support frame, a headrest component and a reset member. The support frame is pivotally connected with the headrest component, and the reset member is connected with the headrest component and configured to drive the headrest component to rotate relative to the support frame. The support frame is provided with a limiting convex block, and the limiting convex block can stop a rotation of the headrest component when the headrest component moves to an initial limiting position.
