Abstract: A chair having an adjustable backrest and control actuator disposed forward of the backrest hinge, for controlling the backrest angle. The chair has a backrest support hinged to the backrest away from the backrest/chair hinge, and coupled directly or indirectly to track runners which run along elongated support tracks. A positioner is controlled by the control actuator and coupled to the backrest support and track runners, limiting the extent to which the track runners may move along the support tracks and thus control the angle of the backrest.

Abstract: An adjustable poolside chair comprises a chair assembly, a height-adjustable support mechanism, and a weighted base. The chair assembly comprises an outdoor padded chair with a tilting back portion and is constructed of lightweight, waterproof materials. The weighted base comprises a pair of horizontally adjustable hooks which are extended around a lip of a pool. The base also comprises a pair of rollers for transportation of the chair. The adjustable support mechanism comprises a height adjustable pneumatic cylinder and also provides a swivel function. In use, the base is placed in a desired location and the hooks are extended around the lip of the pool and secured in place using tightening knobs, thereby providing additional stabilization of the chair in a poolside position.

Abstract: A foldable leisure chair includes a seat unit having a pair of side frames, a pair of armrest members connected pivotally and respectively to the side frames, and a pair of support units. Each support unit includes a coupling seat defining a receiving space therein and having a pivot end part that is connected pivotally to a respective side frame, a seat-engaging rod having an engaging end part that extends telescopically into the receiving space and a connecting end part that is connected pivotally to a corresponding armrest member, and an adjusting mechanism disposed in the receiving space for positioning the seat-engaging rod relative to the coupling seat so as to maintain the corresponding armrest member at a selected one of a plurality of angular positions relative to the respective side frame.

Abstract: A chair (1), in particular a dentist's chair, which has a seat (3) and a backrest (2) which are connected with each other by means of a hinge (6) consisting of two movable parts in the from of an inner ring (8) and an outer ring (7) disposed concentrically therewith. The inner ring (8) is secured to the seat (3), while the outer ring (7) is secured to the sear (3). The outer side of the inner ring (8) engages the inner side of the outer ring (7), a ball bearing (11, 12) being mounted between the inner ring (8) and the outer ring (7). The invention provides a dentist's chair where the armrest follows the movement of a user's back.

Abstract: An apparatus for simultaneously folding seat back and armrest, which comprises a seat assembly, a seat back assembly, a pivoting assembly, two armrests and an adjusting assembly. The seat assembly is mounted on a base of a chair. The seat back assembly is pivoted to the seat assembly. The crank is pivoted in the seat assembly in such a manner that both ends of the crank protrude out of the seat assembly, and the protruded ends are swingable along with the rotation of the crank. The two armrests are arranged at both sides of the seat assembly and the seat back assembly; an end of each of the armrests is pivoted to the crank, and another end of the armrests is pivoted to the seat back assembly. The adjusting assembly is disposed between the seat assembly and the seat back assembly for controlling the motion of the seat back assembly and the armrests.

Abstract: A chair with four sets of leg tubes(22) consisting of two leg tubes(22) attached at their centers in an X position which fold into a collapsed position with leg tubes(22) nearly parallel to each other. Seat tubes(24), and back tubes(44) are pivotally attached to the upper ends of leg tubes(22) at the rear of the chair. Seat tubes(24) are connected to leg tubes(22) at the front of the chair by seat clips(30). This configuration of the chair in the open position, provides a stable structure for the attachment of a seat cover(42) and for the attachment of a mechanism for reclining back tubes(24) and back cover(11). Arm braces(18) extending from the top of leg tubes(22) at the rear of the chair, and connected to vertical tubes(14) extending from near the center of seat tubes(24) support arm tubes(8), which are attached to back tubes(44). Back tubes (44) recline by moving arm tubes(8) to different positions in slots in arm plates(12) attached near the front of arm tubes(8).

Abstract: An adjustable armrest or humeral junture support for use with a chair having a seat and a reclining back. The armrest includes a first rail member attached to the side of the chair back, and a second rail member attached to the side of chair seat. Also, a first sliding member is coupled to the first rail member for sliding along the first rail member and with a locking structure for locking the first sliding member along the first rail member. A second sliding member is coupled to the second rail member for sliding along the second rail member and with a locking structure for locking the second sliding member along the second rail member. An armrest is located adjacent the side of the chair and has a front attachment portion and a back attachment portion and has the back attachment portion of the armrest pivotably attached to the first sliding member for rotational movement about the first sliding member.

Abstract: A beach chair is made of three tubes, the tubes being bent three-dimensionally, and a method renders the forming economical. The three tubes are bent into the same shape, including parallel legs and a bend connecting the legs. The bend is also curved out of the plane of the parallel legs. The seat has a sling between two legs, and the bend turns down to act as a rear support; the back extends up from the seat; and, a support connects the seat and back for rigidity, and the bend turns down to act as a front support. An optional leg rest is the same shape again, having its legs attached to the seat, and its bend turning down to support the leg rest. To bend the tubing, a thermoplastic trough is shaped as desired, and a heated tube is conformed to the trough.
