Description

A kind of chair

Technical field

This utility model relates to field of furniture, more specifically, it relates to a kind of chair.

Background technology

Chair and stool are very common in life, the two is distinctive in that chair often relatively many backrests of stool, user is had and more comfortable takes a seat experience, but, the structure of chair relatively stool is more complicated, it is not easy storage, use be not as convenient as stool in specific occasion, in prior art, also the design that some chairs and stool can be changed mutually is occurred in that, if the patent No. is the Chinese patent of CN202312307U, propose the chair of a kind of backrest capable being deformed into stool, it makes chair be transformed into stool by backrest rotation is fitted to seat, use thus convenient, but that does not take into account user while considering conversion takes a seat experience, reduce the practicality of chair, this is accomplished by a kind of comfortable and that self can be converted to stool chair.

Utility model content

For the problem in practice, the utility model proposes a kind of chair, concrete scheme is as follows:

A kind of chair, including chair lower limb, seat plate and the dependence plate with the hinged setting of seat plate, described dependence plate is provided with chute along its length, and described dependence plate is provided with air cushion towards the side of seat plate, and described air cushion is connected with leaning on plate sliding；It is additionally provided with between described seat plate and dependence plate for controlling seat plate and leaning on the angular adjustment assembly of angulation between plate.

Pass through technique scheme, can lean on plate by rotation makes dependence plate fit with seat plate, make chair be converted to stool to use, by arrange air cushion can more existing convertible state chair promote occupant take a seat experience, in use, gas in air cushion according to the height needing adjustment air cushion of self, after chair is converted to stool, can be drained by user.

Further, described air cushion is fixedly connected with connecting plate towards the one side leaning on plate, and described connecting plate is provided with projection towards the one side leaning on plate, and described connecting plate is connected with chute sliding.

By technique scheme, facilitate air cushion along chair back length direction sliding.

Further, described air cushion arranges in multistage along its length and is equipped with airtight valve on every section of air cushion.

By technique scheme, air cushion is that multistage is independently arranged, and also allowing for air cushion can be regulated according to the build that user is different, and what promote occupant further takes a seat experience.

Further, described angular adjustment assembly includes one and fixes, with leaning on plate lower limb, the fixing bar being connected, the length of described fixing bar is all stretched out from the both sides of the edge leaning on plate more than the width and its both ends that lean on plate and all movable sleeve is provided with sleeve, and the surface of described sleeve is fixing with the upper surface of partial panel to be connected；The outer wall at the both ends of described fixing bar is provided with locking groove along its length, the outer wall of described fixing bar is arranged with the collar, the length sum of described sleeve and the collar is not more than the length of described locking groove, the lateral wall of the described collar is provided with groove and is connected with described fixing bar sliding, and the inwall of described sleeve is evenly arranged with the double wedge suitable with described groove along its circumference；Being provided with elastic component between the described collar and fixing bar, the preset elastic force of described elastic component makes the groove of collar lateral wall mutually meshing with the double wedge of sleeve medial wall.

Pass through technique scheme, when needs rotate and lean on plate, have only to promote the collar along fixing pole length direction, groove is separated with double wedge, and the collar and fixing bar are active again, at this moment rotate and lean on plate, when leaning on plate and turning to predetermined position, stopping promoting the collar, the collar is returned to initial position under the effect of elastic component, leans on plate again locking with seat plate.

Further, described elastic component is spring, and one end of described spring and fixing bar are fixing to be connected, and the other end and the collar are fixed away from one end of sleeve and be connected.

Further, the upper surface of described seat plate is provided with the depression adapted with human buttock.

By technique scheme, what namely improve occupant takes a seat comfort level, and after making again seat plate fit with dependence plate, the air cushion after venting can be placed in depression.

Compared with prior art, this utility model will be by leaning on plate and the hinged setting of seat plate, making to lean on plate can with chair panel attachment, it is achieved thereby that chair is to the transformation of stool, by arranging multisection type air cushion moving up and down, improve the comfort level that takes a seat of user further, simple in construction, convenient and practical.
