Abstract
The utility model discloses a kind of seat bearing structure and seat, including elastic telescopic support member, elastic telescopic support member carries extendable room in middle formed is divided among above and below closed ring body structurc, and elastic telescopic support member；Rear support arm, is that one extension is formed backward upwards by the rear end of elastic telescopic support member；When the pressure that inclines acts on rear support arm, rear support arm is transmitted downwards under pressure effect of inclining from initial position elastic deformation backward, the pressure that inclines backward by rear support arm, drives elastic telescopic support member to expand upwards, carrying extendable room increase；When the pressure that inclines on rear support arm reduces and disappears, elastic telescopic support member is gradually reset to original state.The seat bearing structure adaptivity is strong, and with more hommization, universal performance is good, equips the seat of this seat bearing structure, different according to user, and chair back-rest inclination matches with gravity falling back power, and anyone easily can stand up in reclining reply.
Description
Technical field
The utility model is related to the technical fields such as swivel chair, office chair, more particularly to a kind of seat bearing structure and seat.
Background technology
Revolving chair chassis, also referred to as Revolving chair tray, are installed in an important component below swivel chair seat cushion, and the lifting of seat cushion is leaned on
The elevation angle regulation of the back of the body is all completed by chassis.
Chinese patent literature (the day for announcing：On December 24th, 2014, notification number：CN104223821A a kind of swivel chair) is disclosed
Chassis, including base, bracket and seesaw, bracket are arranged in base, and seesaw is arranged in bracket, seesaw using the first bearing pin as turn
Activity supporting point, the first bearing pin is connected through bracket and with base, and seesaw front portion prizes bracket by first connecting rod, second connecting rod, the
One connecting rod is connected with second connecting rod by the 3rd hinge and the 3rd bearing pin with bracket, and second connecting rod is installed with the second bearing pin and
Two bearing pins pass through or avoided after bracket to be connected with base, rail groove are symmetrically offered in the both sides of bracket, the first bearing pin is located in
In rail groove, the chassis also includes enabling the elasticity reset device that bracket sets back after seesaw prizes movement of bracket.Dress
The swivel chair or seat on this standby chassis, according to human body weight, backrest reclining restoring force has corresponding matching so that no matter body weight it is light or
The people of weight easily can stand up in reclining reply.
Specifically, the first bearing pin of the patent, the second bearing pin, the 3rd bearing pin, the 4th bearing pin, seesaw, first connecting rod,
Two connecting rods formation four-point linkage mechanism, forms the conduction of power, the chair back is connected and fixed on seesaw as the driving of four-point linkage mechanism
Power, human body puts on the reply that threeth bearing pin formation of the gravity of seat support by being articulated with bracket is applied to four-point linkage mechanism
Power, driving force and restoring force the formation Antagonistic Relationship of four-point linkage mechanism.
During human body backward reclining, the second connecting rod of four-point linkage mechanism progressively subtracts with horizontal acute angle
Small, then bracket puts on the revolving force component increase of second connecting rod, so as to realize reply of the gravitational load for quadric chain
Force square is incrementally increased, and is resisted with the driving force formation that incrementally increases, restoring force to the elastic-restoring force of elasticity reset device according to
Bad smaller, applicable crowd's scope is wider, and the lighter or heavier people of body weight easily can stand up in reclining and reply, therefore for every
The people of individual different weight can reach most Proper Match restoring force.
The realization of above-mentioned adaptation function is realized by the chassis on seat or swivel chair, but chassis is usually
Metal is made, and correspondingly employs corresponding structure, and chair overall weight is heavier, and cost is higher, it is therefore necessary to which exploitation is a kind of
The lightweight seat of effect same can be achieved, to reduce chair overall weight, cost is reduced.Different people can be disclosure satisfy that simultaneously
The demand of group, the lean forward size of power that can be applied according to different human body of amplitude size of hypsokinesis of the supporting construction is automatically adjusted.
Utility model content
The purpose of this utility model is in order in the presence of overcoming the shortcomings of above-mentioned prior art, and to provide a kind of light weight
Change, can be automatically adjusted according to different users power size seat bearing structure and application on the seat, can meet
Different crowd, the people of different weight are used, when not only solving the backrest reclining of conventional seat, and lumbar supporting position skew is brought
Discomfort, so as to improve comfort level when different human body is used；And during chair back-rest inclination, load on seat support
Gravity be transmitted to the ratio of chair back restoring force can be different because of different users, all the time being capable of basis in whole process

Integrated support structure.
The seat bearing structure, is made up of elastic telescopic support member 1 and rear support arm 3, and elastic telescopic support member 1 is with after
Support arm 3 is respectively that elastic flexible material is made, in use, directly utilizes elastic telescopic support member 1 and rear support arm 3
The transmission of power is carried out, and is acted on by the elastic deformation of material, the hypsokinesis of seat bearing structure is realized and leans forward.The seat is carried
Structure, goes for anyone, will not because human body difference and discomfort occur, as different users in use, its backward
The power for pressure of inclining it is of different sizes, the position of applying power is also different, and size that rear support arm 3 can be according to the power of application and position
Put and tilt backwards, rear support arm 3 is tilted backwards, power is directly delivered on elastic telescopic support member 1 by rear support arm 3, elasticity
The motion upwards under force of telescopic support 1 so that carrying extendable room 2 increases, and human body is tilted backwards upwards, can be very
Reclined comfort point is able to conveniently find, and when people's bench over, the power on rear support arm 3 disappears, and on elastic telescopic support member 1
Carry the weight of human body, and transmit the force to rear support arm 3, rear support arm 3 under the drive of elastic telescopic support member 1 forward
Reset or tilt, make the sitting posture of human body more comfortable.
As shown in figure 5, during initial position, the carrying extendable room 2 on elastic telescopic support member 1 keeps relatively small, when
People sits and leaned on backward on the seat, when tilting backwards rear support arm 3, by the conduction of the formation power of rear support arm 3, to elastic telescopic
Support member 1 is with upward power so that while upper supporting piece 5 is pulled rearwardly, be lifted up again, now, lower support element 6
It is pulled rearwardly and relative upward movement, and the power suffered by upper supporting piece 5 carries flexible much larger than the power suffered by lower support element 6
Space 2 increases, and the restoring force that the gravity formation elastic telescopic support member 1 that human body is applied on elastic telescopic support member 1 resets,
Relation of confronting with each other is formed between hypsokinesis pressure and gravity falling back power so that human body and rear support arm and elastic telescopic support member are tight
Closely connected to close, according to human body weight, chair back-rest inclination restoring force is mutually matched so that no matter body weight gently or again, no matter the people of height
Easily reclining reply it can stand up.
