Abstract

The utility model relates to an improved structure of a chair back supporting frame. A middle transversal supporting part extended horizontally is arranged in the middle section, a slant stretching part is slantingways extended under the middle of the side direction of the both ends of the middle transversal supporting part, two horizontal stretching parts which are parallelly stretched are engaged at the other ends of the two slant stretching parts respectively through a vertical stretching part, at least one fixing piece is arranged between the two supporting parts, in addition, a plurality of positioning holes are arranged on the fixing piece and are used for the corresponding positioning components to be penetrated and fixed at the bottom side of the seat pad, the middle transversal supporting part can be provide for at least one chair back to be bonded and fixed, thereby the stable and comfortable chair back supporting structure is formed.

Description

The chairback brace of seat improves structure

Technical field

The utility model relates to a kind of assembly of seat, particularly relates to a kind of simple in structure, with low cost and chairback brace that have a seat of multidirectional support elastic and improves structure.

Background technology

The conventional seat structure, useful its chair back combines with other position (seat cushion, leg, handrail etc.) of this seat or is one-body molded, therefore its chair back can't be adjusted because be subjected to fixing, therefore this seat relatively lacks the comfortableness on using owing to be difficult to do suitable adjustment according to different users's stature;

Have in addition below the seat cushion of seat in conjunction with a L shaped chairback brace structure, this L shaped chairback brace is to be extended upward by this seat cushion rear, and upwards in conjunction with this chair back, this structure itself because during this L shaped chairback brace stress deformation, can produce a suitable restoring force, make its chair back can when the user swings back, form a resiliency supported, the comfortableness in the time of can promoting its seat and lie; Yet the chair back of this single L shaped chairback brace structure lacks the support of both sides, and its chair back is waved to both sides easily in use, influence the comfortableness that its seat is lain, and the bond strength of its chairback brace is also more relatively poor, and Chang Rongyi is loosening, break away from.

The utility model content

Main purpose of the present utility model is to provide a kind of chairback brace of seat to improve structure, and it can effectively avoid chair back lateral oscillation action improperly, can improve the comfortableness and the stability of sitting when lying.

Another purpose of the present utility model is to provide a kind of chairback brace of seat to improve structure, and its chairback brace has higher structural strength, can effectively improve its total quality and service life.

The utility model for achieving the above object, adopted following technical scheme: a kind of chairback brace of seat improves structure, it is provided with the horizontal branch in a horizontally extending centre in the stage casing, for fixing at least one chair back, both end sides in this horizontal branch in centre is tiltedly stretched portion to the middle oblique extension one in below, and make this two the other end of tiltedly stretching portion form the horizontal-extending portion that extends in parallel, for the seat cushion bottom side that is incorporated into this seat.

After the utility model adopts technique scheme, efficiently solve the problem that prior art exists, have higher structural strength, and can improve the comfortableness and the stability of sitting when lying, can effectively improve its total quality and service life simultaneously.

The specific embodiment

Please join Fig. 1,2, from wherein can clearly finding out, the disclosed chairback brace 1 of the utility model mainly is to be provided with the horizontal branch 11 in a horizontally extending centre in the stage casing, respectively be provided with a location screw 111 in the both sides, stage casing of the horizontal branch 11 in this centre, and distolaterally outside it tiltedly stretch portion 12 to the middle oblique extension one in below respectively, and extend a vertical stretch 121 respectively downward vertically in this two other end of tiltedly stretching portion 12, form the horizontal-extending portion 13 that is parallel to each other and extends in each vertical stretch 121 end again, and between two horizontal-extending portions 13, be provided with a plurality of stators 14 with locating hole 141, make this locating hole 141 run through seat cushion 41 bottom sides of being fixed in seat 4 for relative positioning component;

Above-mentioned chairback brace 1 is when practical application, it can cooperate a fixation kit 2 in conjunction with the chair back 3, wherein this fixation kit 2 is provided with a recess 21 in a side stage casing, can be sleeved on the surface, positioning screw hole 111 position of the horizontal branch 11 in this centre, and be provided with a medium pore 23 that connects in these recess 21 central authorities, can connect and be incorporated in this positioning screw hole 111 for a central conjunction 231 (bolt), then be respectively equipped with a side opening 22 that connects in the both ends of fixation kit 2 in addition, can oppositely run through and be incorporated in the locating hole 31 corresponding on the chair back 3 for both sides conjunction 221 (bolt).

Fig. 3, the 4th, the utility model application implementation illustration, shown in this two figure, as can be known in use, utilize two settings of tiltedly stretching portion 12 and vertical stretch 121, can effectively increase the bulk strength of chairback brace 1, can bear the user and sit the weight of lying, this chairback brace 1 also can produce longitudinally suitably strain when stressed simultaneously, and then improves the overall comfort of this seat 4.

In sum, the chairback brace of the disclosed seat of the utility model improvement structure has the structure letter Single, with low cost and can improve the effect of comfortableness.
