Chairs, seating systems, chair sub-assemblies and sub-systems, and associated methods of assembly and use. Aspects relate to chairs and methods of assembling chairs including chair controls of a relatively compact and effective design with desirable synchronous raising and tilting motions. Aspects also relate to tilt lock assemblies for achieving secure and effective tilt securement. Additional aspects relate to forward and rearward adjustment, or extension and retraction, of a seating assembly of the chair.

A quick-exit assembly for reclining furniture, including motorized versions, is provided. An exemplary quick-exit assembly may include a linkage assembly configured to move between a first position and a second position. A drive mechanism may be coupled to the linkage assembly, and may be configured to move the linkage assembly between the first position and the second position using an actuator, and also, allow movement of the linkage assembly between the first position and the second position using manual force with reduced restriction from the drive mechanism.

An office chair including a base, a seat, a chair column that extends in the vertical direction between the base and the seat, and a backrest, further comprising an electric drive unit that comprises an electric motor and a change gear, the change gear being designed to input the rotational force of the electric motor into a first adjustment device for adjusting a seat height of the seat and converting said force in a second adjustment device for adjusting a tilt of the seat or the backrest.

Disclosed in this application is a chair capable of permitting a user to quickly and easily change his or her posture by tilting a back support in a state in which the user takes a seat. The chair includes a seat support; a back support which has a back frame, with a lower end being connected to a rear end of the seat support by a pivot shaft, so that the back support is tilted in a rearward direction; and a footrest which is engaged to the seat support, so that the back support is interlocked with the footrest.

The present invention provides an office chair (2) comprising a base (8), a seat (4), a chair column (6) that extends in the vertical direction between the base (8) and the seat (4), and a backrest (12), further comprising an electric drive unit that comprises an electric motor and a change gear, the change gear being designed to input the rotational force of the electric motor into a first adjustment device for adjusting a seat height of the seat (4) and converting said force in a second adjustment device for adjusting a tilt of the seat (4) or the backrest (12).

Disclosed is an adjustable chair for use during post-surgical recovery, including a seat with an opening adapted to reduce or eliminate pressure on the buttocks and hips when a user is seated.

Seating furniture, in particular, a chair having a plane of symmetry, a seat surface, a backrest, a kinematic arranged on a base of the seating furniture, which has a base arm, which is rotatable relative to the base around a base axis (A1), an end arm, which is rotatable around a base arm around an intermediate axis (A2), and a furniture part that is mounted to rotate around the end arm around an end axis (A3), where the three axes (A1, A2 and A3) intersect at a central point (Z, Z1). To achieve versatile mobility, the pivotable furniture part is the backrest, that the seat surface is mounted to rotate relative to the backrest around a connection axis running orthogonally to the plane of symmetry, and that the seat surface is connected to the base via a support kinematic that constrains at least one degree of freedom.
