A reclining chair or the like provides a set of base-mounted extendable arms that extend outward as the chair reclines to brace the chair against tipping. A force-limiting coupler allows the reclining mechanism and the extendable arms to be linked while maintaining different force regimes.

A chair comprises a seat pan member, a seat back member having a lumbar support member, a lumbar support assembly operatively connected to the lumbar support member and configured for moving the lumbar support member, with respect to the seat pan member and the seat back member, between at least a first position and a second position, and an actuator configured to operate the lumbar support assembly for movement of the lumbar support member between at least the first position and the second position. When the lumbar support member is in the second position, the lumbar support member is positioned forwardly, in a direction toward the seated user's lower back, relative to the seat back member so as to enable the user to be seated forwardly on the seat pan member while being engaged with the lumbar support member.

A chair of an aspect of the present disclosure includes: a support base; and a chair body including a seat frame that extends in the forward-rearward direction and forms at least part of a seat, and a back frame that is provided in the rear end of the seat frame to be pivotable around an axis O1 extending in the left-right direction, extends upward from the seat frame, and forms at least part of a backrest. The support base includes a slider that supports, in front of the axis O1, the seat frame movably in the forward-rearward direction, and a backrest-supporting shaft that supports, below the axis O1, the back frame pivotably around an axis O2 extending in the left-right direction.

A patient support apparatus includes a frame, a stationary member mounted relative to the frame, a movable member having a pivot member rotatably mounting the movable member about the stationary member, and a fastener securing the pivot member to the stationary member. The patient support apparatus also includes a joint between the pivot member and the stationary member, which is configured to apply a tension force on the fastener.

The present application relates to a chair which adapts to dynamic body postures of a user. The posture adaptive work chair includes a seat sub-assembly having a front edge and a seat base sub-assembly; a pair of spine members cantilevered from the font edge of the seat sub-assembly; a back sub-assembly supported by the pair of spine members, and configured to flex in multiple axes based on a direction of load applied by a user; and a tilt limit lever movably coupled to the seat base sub-assembly and configured to enable tilting of the back-sub assembly to a plurality of tilt positions.

A patient support apparatus includes a frame, a stationary member mounted relative to the frame, a movable member having a pivot member rotatably mounting the movable member about the stationary member, and a fastener securing the pivot member to the stationary member. The patient support apparatus also includes a joint between the pivot member and the stationary member, which is configured to apply a tension force on the fastener.

The present invention relates to ergonomic supports in medical environment. In order to provide improved ergonomic support while providing a minimum impact of the user's activities, an ergonomic support device (10) for users in medical environment is provided. The support device comprises a seating support arrangement (14), an X-ray shielding arrangement (18) and a base support structure (12). The base support structure provides mechanical support for the seating support arrangement and the X-ray shielding arrangement. The seating support arrangement comprises a seat support surface (16) that is configured for supporting a buttocks area of a user. The X-ray shielding arrangement comprises at least one X-ray shield (20) that is configured for shielding at least a part of an X-ray radiation to which a user is exposed to while supported by the support surface. The at least one X-ray shield is movably mounted to the base support structure to be adjustable in its position relative to a user at least partly resting on the seat support surface.

The embodiments relate to a geometric under structure, central and outer hub for a GFN plastic chair base. The geometric shape and dimensions are critical components to the overall strength of the chair base hub and arms when either vertical or rotational forces are applied at the central hub. The central hub is of sufficient thickness to maintain dimensional stability when the forces are applied. The overall geometry and material composition enable the hub area to be constructed with minimal plastic wall thickness while optimizing the physical strength of the article and facilitating high production rate.

A reclining chair or the like provides a set of base-mounted extendable arms that move forward as the chair reclines, and the leg rest extends to brace the chair against forward tipping, for example, if weight is applied to the leg rest without the counterbalance of an occupant. When the leg rest retracts, the arms pull back to reduce tripping hazard.

An apparatus configured to convert between a cart and a lounge chair comprising a bottom portion, backrest portion, a leg rest portion, first and second removable side portions. The backrest and leg rest potions rotatably coupled to the bottom portion and movable between open and upright positions. The first and second removable side portions being coupled to the backrest and leg portions when in the upright positions, wherein an open carton of the cart is formed by the bottom portion and the leg rest and backrest portions when in the upright positions, and the first and second removable side portions when connected to the leg rest and backrest sides, and the leg rest and backrest portions, when in the outward positions, form a seat, a leg rest and a backrest of the lounge chair, respectively, the lounge chair being configured to support a person in a sitting or lounging position.
