Description

The seat base of slip

Technical field

The utility model mainly discloses a kind of seat base, the slip seat base that You Zhike reduces fault rate and reduces cost.

Technical background

General traditional seat all designs the function of backrest reclining, only when the backrest hypsokinesis, because seat cushion still remains in original position and moves after can't following backrest, can make the interval of backrest and seat cushion tail end excessive, so will make being against on the backrest that the occupant can't be docile fully, leg joint is stuck in stick up the seat cushion leading edge behind the height, more uncomfortable in the use.The applicant once designed the seat base of slip, and was as described below:

With reference to the known slip seat base of Figure 10, it mainly includes a pedestal 10 and a tailstock 20; This pedestal 10 has first end and second end, and the both sides of this pedestal 10 are respectively equipped with a wallboard 11, and these wallboard 11 upper limbs are formed with a track 12; This tailstock 20 is hubbed on the two side wall panels 11 of this pedestal 10, and can tilt with respect to this pedestal 10 pivots pendulum, this tailstock 20 has first end and second end, second end of this tailstock 20 can connect establishes backrest 62, the both sides of this tailstock 20 are combined with an arm-rest frame 25 respectively, this arm-rest frame 25 can be for articulating a base plate 50, the top side of this base plate 50 can be in order to installing seat pad 63, the bottom side of this base plate 50 then is respectively arranged with a roller 51 with respect to the position of these pedestal 10 tracks 12, and this roller 51 can move on this track 12; By this, when backrest 62 receded, this tailstock 20 can drive this base plate 50 simultaneously and move backward, makes seat cushion 63 reach the action that moves after the level.

And conventional construction is contacted with on this track 12 owing to this roller 51 only utilizes the deadweight of seat cushion 63, there is no spacing design mutually between this roller 51 and this track 12, so take mode or external force collision improperly improperly because of the consumer easily, and make roller 51 that offset track 12 be arranged and come off, cause the shortcoming of fault.

Moreover its overall construction design is comparatively complicated, as the design of tension adjusting device 30 and positioner 40, the assembling between the spare part with cooperate, all can't the effective simplification processing procedure, just can't reduce production costs certainly.

Because the disappearance of above-mentioned conventional construction, the utility model creator invents out a kind of seat base of slip, and it can reach when the backrest hypsokinesis, and seat cushion still keeps the back mobile work of level, can overcome all shortcomings of above-mentioned habit formula goods.

Summary of the invention
