A portable frame apparatus and associated methods of use are disclosed. The apparatus includes a frame. The frame includes a first support member, a second support member, and at least one connecting member. The connecting member is configured to be coupled to the first support member at a first end of the connecting member and to the second support member at a second end of the connecting member. The first support member, the second support member and the connecting member form a rigid structure that provides support to a user of the portable frame apparatus.

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.

A foldable massage chair, including a face pillow assembly for supporting a user's head, a chest pillow assembly for supporting the chest, a handrail assembly for supporting wrists, a front support piece, a seat cushion assembly, a main supporting frame, a kneeboard assembly, and back and a front supporting leg assemblies. When using this chair, it is placed in an expanded or use position, so a user may sit on the seat cushion and lean on the massage chair, completely exposing his back, waist, and hips for a masseur to massage. When the chair needs to be put away, it is possible to fold the chair into a collapsed position by folding the seat cushion assembly, front support piece, chest pillow assembly, and handrail assembly. Also, the front and back supporting leg assemblies are folded underneath and towards the main supporting frame. Consequently, the size of the entire chair decreases.

A piece of furniture, in particular a piece of seating furniture, has a base part on which a movable furniture part is pivotably mounted via at least one pivot fitting, wherein the at least one pivot fitting is fixed to the base part by means of a first lever and is fixed to the movable furniture part by means of a second lever which is arranged pivotably with respect to the first lever, and a method for assembling a piece of furniture.

A seating arrangement includes a seat portion, a back portion, a support member caused to move between first and second positions, and a back recline lock arrangement that includes an actuator, a lock member caused to move between a locked position when the actuator is in an engaged position where the lock member prevents the support member from moving from the first position toward the second position, and an unlocked position when the actuator is in a disengaged position, and wherein the actuator is configured to move from the disengaged position to the engaged position when the chair back is in the reclined position, and the lock member is prevented from moving from the unlocked position to the locked position until the back assembly is moved from the reclined position to the upright position.

An adjustable armrest assembly provides for quick and easy height and tilt adjustments to the armrest. Generally, the armrest assembly disclosed herein includes a base, an armrest, and one or more shafts extending from the base and being pivotably coupled to the armrest. By moving the one or more shafts relative to the base, the height and/or tilt of the armrest relative to the base can be adjusted.

An armrest may comprise a first casing and a second casing coupled to the first casing. An angular armrest adjustment assembly may be located between the first casing and the second casing. The angular armrest adjustment assembly may comprise a hub coupled the first casing, a lever ring configured to engage a splined surface of the hub, and a biasing member configured to bias the second casing away from the lever ring.
