Description

The adjustment structure that chair tool waist leans on

Technical field

The utility model relates to a kind of chair back and is provided with the waist headrest that can adjust position and location up and down, allows the operation of adjustment more simple and easy simultaneously.

Background technology

About existing we the backrest of known chair tool, some design has can adjust the device of waist by the position, shown in No. 01219018.7 patent of China, it is to be installed with the breasting face (wire side) that is subjected to occupant's leaning on back on the support body of the chair back, and between chair back support body and breasting face, if one can stay on the waist headrest at the back side of breasting face, make and allow this waist headrest can be the waist place that is positioned at the occupant of breasting face, have suitable support effect and can not cave in, and then allow occupant's waist be supported, make the occupant feel comfortably cool, reduce tired generation, enable to be more suitable for taking for a long time.

And the two ends of above-mentioned waist headrest are slidedly arranged on the slotted eye of two relative adjustment seats, and then make outside this waist headrest moved up and down, and can lean on the difference of angle and swing along with human body, and there be cooperating of tightness slightly by between its combined block and the slotted eye, and allow the waist headrest adjust up and down behind the position and can locate, but can just can't again the waist headrest be located firmly because of after skimming wear become flexible between combined block and the slotted eye; Simultaneously when moving up and down the waist headrest, also can be because of the fulcrum apart from each other of both sides, and if the point of application is when the centre place of waist headrest, the as easy as rolling off a log unbalance stress that causes combined block place, both sides, and the phenomenon that makes waist headrest generation deflection move, and then the difficulty that causes the waist headrest to be adjusted.

The utility model content

The waist headrest of above-mentioned existing chair tool is in operation, the problems such as difficulty that can get loose and move, the practiced solution of the utility model, be to set firmly a sliding slide guide of establishing a slide assemblies between both on the chair back of order corresponding to the human body waist to cover, and the overhanging end that makes this slide assemblies be provided with pulling department and with a waist headrest pivot admittedly together, and make on the corresponding surface of the slide assemblies and the chair back and establish a plurality of locating holes, simultaneously therein on the pairing chair back of a locating hole, establishing one can elastic telescopic and front end can embed the positioning component in this locating hole.

The beneficial effects of the utility model are, by the pulling of above-mentioned slide assemblies described in the utility model, can do the adjustment of differing heights to the waist headrest, after being adjusted to book office, locate immediately simultaneously, and then make outside the user can operate easily, and the problem that does not more have a difficulty that gets loose or slide takes place.

1. chair back among the figure 10. hold the hole, 2. spring, and 3. positioning component, 31. build-in portions, 32. stop sections, 4. slide assemblies, 41. pin fixed parts, 42. pulling departments, 43. chutes, 44. conduits, 45. locating holes, 5. slide guide covers, 51. guide rails, 6. waist headrest, 61. pin fixed parts.

The specific embodiment

Please consult Fig. 1,2 and Fig. 3, shown in 4, the chair back 1 of the present utility model is provided with can be for the screen cloth face (not shown) of occupant's leaning on back, the chair back 1 and net are then established a waist headrest 6 between face, this waist headrest 6 is provided with situation again, slide guide covering 5 is fixed at the waist place that comprises the corresponding human body on the chair back 1, and the place is convexly equipped with a guide rail 51 in the middle of the inboard of slide guide covering 5, and between the slide guide covering 5 and the chair back 1, establish a slide assemblies that can slide up and down 4, the place then establishes a chute 43 that can supply guide rail 51 to slip in the middle of the lateral surface of this slide assemblies 4, and establishing one at the upper end of slide assemblies 4 can be for the pulling department 42 of hand grasping, simultaneously make the upper end slightly of slide assemblies 4 establish a pin fixed part 41 again, make with a waist headrest 6 pin fixed part 61 pivots behind admittedly together, and then make slide assemblies 4 then establish a conduit 44 corresponding to the face of the chair back 1, be provided with a plurality of spaced locating holes 45 again in the bottom surface of this conduit 44; And then, make again and offer an appearance hole 10 on an above-mentioned wherein locating hole 45 pairing chair back, and in this appearance hole 10, be provided with the positioning component 3 that is subjected to a spring 2 outside pushing tows, and the front end of this positioning component 3 be provided with can be for the build-in portion 31 that embeds in the locating hole 45, and be equipped with slippage at build-in portion 31 rear sides and lead stop section 32 in 44 in groove.

So, when user's desire is adjusted the height of waist headrest 6, as long as to pull the pulling department 41 of moving slide assemblies 4 upper ends, can drive waist headrest 6 as shown in Figure 5 and do the adjustment in precalculated position up and down, and when waist headrest 6 is adjusted the height of institute's palpus, this positioning component 3 can embed in the locating hole 45 of corresponding position, and then waist headrest 6 location are lived; Simultaneously, as shown in Figure 6, when occupant's waist rested on the waist headrest 6, this waist headrest 6 also can lean on the difference of angle along with human body, and waist headrest 6 also can be swung thereupon, made between its energy and the human body more docile and comfortable.

So the operation of above-mentioned waist headrest 6 of the present utility model owing to make the upper end of slide assemblies 4 be provided with pulling department 41, allows outside the user more can operate easily, the location of this waist headrest 6 is more easy and be difficult for slippage.
