Fig. 2 is its whole rearview with handrail-type,

Fig. 3 is its partial side view that does not have handrail-type,

Fig. 4 is its fragmentary, perspective view,

Fig. 5 is provided with its perspective view of the Lordosis support of filling for backrest,

Fig. 6 is its perspective view that has the Lordosis support that does not have filler,

Fig. 7 shows the partial, exploded perspective view that it has Lordosis support, and

Fig. 8 is the detailed perspective cutaway view, of the connection between Lordosis support and the backrest.

The specific embodiment

From accompanying drawing as seen, seat of the present invention is the same with most of office seats, comprises pedestal 2, and it has five radially whippletrees 4 that are provided with roller 6 in the end, but these rollers can be according to user's requirements and replaced by footing.

Pedestal 2 is provided with conventional cylinder 8 in central authorities, and it is used for vertically regulating the height of above-mentioned seat.

Supporting construction is welded on the bar of cylinder 8, and this structure comprises a pair of annex 10 forward-facing, and this annex 10 carries a pair of connecting rod 12 that is hinged on its end, and the flat board 14 that supports seat cushion part 16 is hinged on the connecting rod 12.

Two arms 18 that support backrest 20 are hinged at its front end and supporting construction.These arms are the same with backrest, all are to form in independent plastic material molded.

Two supporting arm parts 18 are provided with towards interior pin 22, and annex 24 extends downwards from dull and stereotyped 14, and annex 24 is hinged on the pin 22.

So,, formed the quadrangle of articulated type arm by the combination that each annex 10, relevant connecting rod 12, dull and stereotyped 14 form with the front portion of relevant arm 18, this quadrangle can tilt to some extent seat cushion partly and backrest to make the user more comfortable.

The system that is used to make above-mentioned seat flexibly return the system of its static configuration and is used for seat lock is fixed on required operating configuration when not having external carbuncle all belongs to general type, therefore for the simplicity of accompanying drawing demonstration, said system occurs in the accompanying drawings.

The seat portion 16 that is preferably the type of filling is fixed on dull and stereotyped 14 as a rule.

Backrest 20 is made up of the integral structure that is extended by both direction basically, this structure has two external vertical bands 26, belt 26 extends downwards forward to form arm 18, and, separate two long longitudinally slits 27 with central zone because being arranged, except top and bottom section, slit 27 extends on the intimate whole length of above-mentioned backrest.

This central zone flatly is separated into two

parts

28,30 in user's lumbar region, these two

parts

28,30 are separated from each other by the gauffer 32 outstanding backwards and that disconnect in central authorities of level, to form a kind of continuous hinge between two

parts

28 and 30.

Therefore so, although have integral structure and can form by independent injection-molded operation, still can obtain to have elasticity and can surrender backrest partly in user's lumbar region.

Use in the mode that the seat of Sheng Chaning can formerly be described in this way, promptly only have by injection-molded punching press backrest that form or that be provided with filler.In this respect, except the particular configuration because of its structure presents the yieldability, can also make backrest present further yieldability by on backrest, covering the filler (not shown).

These fillers are for example fixed the framework 36 of rigidity is made again the profile of backrest by binding; This then combination can be fixed on the backrest 20, for example is fixed on the backrest 20 by screw.

Backrest 20 can also have the vertically adjustable support member in user's lumbar region.

This support member comprises having the fixed part 38 that is roughly rectangle, is fixed on the backrest by the central disconnected part of screw at described falling hinger 32, and the movable part 40 that is similarly rectangle, can vertically slide with respect to fixed part 38.More precisely, fixed part 38 provides two side flanges 42, and these two side flanges 42 separate from the surface of backrest 20 and are engaged in the vertical slits 44 that is located at the movable part 40.Because the vertical dimension of described flange 42 less than the vertical dimension of described slit 44 relative slip can take place vertically, thereby make adjustment movable part 40 become possibility, wherein movable part 40 formation are with respect to the effective Lordosis support of backrest.

Be the relative position of firm above-mentioned two parts, can use conventional locking piece, perhaps can be provided with simply and have the big contact surface of frictional force.

Can use movable part 40 like this or for it is provided with its special filler, perhaps it is arranged in backrest filler 34 below.When using backrest filler 34 in the support frame 36 at himself, support frame 36 is provided with aperture so that Lordosis support 40 is free to slide.

Improved seat of the present invention can have or not have handrail 48.If have, these handrails are fixed on the flat board 14 of seat cushion part, and then extend up at first outwardly.

In order to make Lordosis support 40 can also regulate height when backrest 20 is coated with filler 34, described Lordosis support is provided with two flanges 46, and flange passes two vertical slits 27 in the backrest and can touch from its rear portion.
