Description

The support of seat improves structure

Technical field

The utility model relates to a kind of support of seat, especially relate to a kind of simple in structure, cost is low, the support of the seat that comfortableness is good improves structure.

Background technology

Traditional armchair structure, majority are that positions such as the leg of seat, handrail, backrest and seat cushion are arranged at respectively on the different support (or fixed position), are connected in series combination mutually with linking assemblies such as bolt or rivets again, form the combining structure of a seat; Yet this armchair structure causes its assembly cost higher because the composition assembly of its each support is more and assembling process is complicated.

Useful in addition tubular body is bent into has leg, the supporting structure at handrail and seat support position, because this seat support has been tending towards integrated structure, therefore can effectively simplify the composition assembly of its support and the installation procedure of seat integral body, can reduce assembly cost, simultaneously, the structure of a part of this type is that the support with the leg position is designed to side-looking and lacks the section configuration that erect on the right one for " mouth " font, utilize its bottom side planar support on ground surface (or other placed side), and with its top side planar support in seat cushion below, utilize its position, stage casing to form the flexible support of a tool, make this seat cushion when stressed, can produce the effect of elasticity lifting, can promote comfortableness; But this structure is not because the backrest position has the strain effect, and it still is not fine making its comfortableness, and it very easily topples over, slides crooked the generation when stressed, and security is not high enough.

The utility model content

Main purpose of the present utility model is to provide a kind of support of seat to improve structure, but it has the back bracket structure of elasticity layback, and can cooperate the lifting of seat cushion elasticity, can effectively improve the comfortableness of seat integral body.

Another purpose of the present utility model is to provide a kind of support of seat to improve structure, the shape of its monolithic seat support, structure have prevent from improperly to topple over, the function of slippage, can effectively improve the security protection effect of seat integral body.

For realizing above-mentioned utility model purpose, the utility model adopts following technical scheme: a kind of support of seat improves structure, it mainly is shaped to a main support with strip shape body, this main support has two and extends in parallel the lower holding part that can support to arrive on ground or placed side, be respectively equipped with a leg that extends vertically upward in this two lower holding parts end, respectively be provided with an armrest support in each leg top side and this lower holding part extends in the same way, and can form two cushion racks parallel and that extend forward in the terminal and downward bending of two armrest supports, and on this two cushion rack, can fix a seat cushion.

After the utility model adopts technique scheme, efficiently solve the problem that prior art exists, effectively improved the comfortableness of seat integral body, can also effectively improve the security protection effect of seat integral body.

The specific embodiment

Fig. 1 is a structure decomposition map of the present utility model, by its entire combination outside drawing with reference to Fig. 2, can clearly find out, the utility model mainly be body formed with bar (pipe) shape be a main support 1, this main support 1 has two and extends in parallel the lower holding part 11 that can support to arrive on ground or placed side, one end of this two lower holding part 11 system is connected mutually with convergence part 112 once, the other end of two lower holding parts 11 then is provided with a upwardly extending leg 13 respectively in conjunction with an expanding part 12 respectively via a depression position in these two expanding parts, 12 outer ends, being respectively equipped with an armrest support 14 in each leg 13 top side extends in the same way with this lower holding part 11, can be on each armrest support 14 in conjunction with a handrail 141, and in two armrest supports, 14 ends be provided with relatively V-shaped downward convergent in the portion 15 of contracting, portion 15 bottom sides of contracting in two then can form the two parallel and cushion racks 16 that extend forward, and be incorporated into two cushion racks, 16 outer ends with a middle convergence part 17, and on this two cushion rack 16, can fix a seat cushion 161, and make this two cushion rack 16 extend to rough 2/3rds position forward by the rear in seat cushion 161 bottom sides, and when practical application, this main support 1 can be in addition in conjunction with the back bracket 2 of a L shaped bending, one end of this back bracket 2 is provided with at least one locating hole 23, be provided with at least one stator 22 in addition in these locating hole 23 sides with plural locating hole 221, make locating hole 23,221 can supply a plurality of positioning component (as: bolts, rivet) runs through and be incorporated into seat cushion 161 bottoms, can form a firm combination, the other end of this back bracket 2 then can be in conjunction with a backing cushion 21;

The utility model in said structure, slipmat 121 before the bottom side of this expanding part 12 and two legs, 13 junctions is respectively equipped with, and be provided with a back slipmat 111 in the both ends of this time convergence part 112 respectively.Fig. 3, the 4th, each enforcement action schematic diagram of the present utility model, shown in this Fig. 3,4, when using as can be known, when this seat cushion 161 stressed (user is seated on the seat cushion 161), can produce a torque to leg 13, make it produce crooked strain, this moment, this seat cushion 161 can elasticity sink, and can promote the comfortableness when sitting; And if during this backing cushion 21 stressed (user is against on the backing cushion 21 with the back), then back bracket 2 can produce and the reverse elastic stretchings of curved shape, make this backing cushion 21 have the comfortableness of facing upward when lying.

In sum, the support of the disclosed seat of the utility model improves structure and can reduce production costs, and can effectively improve safeguard protection and can improve the overall comfort of seat.
