Description
Technical field
Aero seat equipment technical field is the utility model is related to, is related specifically to a kind of new with stronger elasticity recovery
Type aero seat.
Background technology
Seat is indispensable part in train, and the resilient characteristic of backrest directly influences the ride comfort of occupant
Property and then have influence on drive safety.Passenger sit down backward rear backrest when, had to the backrest spring on backrest larger
Elastic deformation, the backside pressure of passenger is reduced by the deformation of backrest, therefore backrest is the portion to be played a key effect in seat
One of part, its recoverability have directly influenced the comfort level of passenger.
In current aero seat, the reply of backrest is typically all to pass through mechanical structure, and its structure is more complicated, cost
It is higher, and repair and change very inconvenient, while response agency can only play simple return action, for backrest
It can not be supported with seat, in the case where seat receives impulsive force, be easily damaged, not possess protection for passenger and make
With.
The content of the invention
Technical problem to be solved in the utility model is the defects of overcoming prior art, there is provided a kind of simple in construction, system
It is easy to make, and increases the elasticity recovery of backrest, reduces the manufacturing cost of seat, while can carry out reinforcement support to seat, improves
The new aero seat of impact resistance and security performance.
To achieve these goals, the utility model uses following technical scheme：
A kind of new aero seat, include seat body, seat body includes chair leg, cushion and backrest, its feature
It is, return mechanism is embedded with inside seat body, and return mechanism is three stage structure, includes three pieces of supporting plates, and be used for
Connect two torsion spring groups of three pieces of supporting plates；Three pieces of described supporting plates be respectively be arranged on backrest in upper plate, installed in seat
Middle plate in pad, the lower plate in chair leg, wherein two torsion spring groups, two torsion spring group difference are installed in the left and right ends of middle plate
Connect and reverse upper plate and lower plate, the end of upper plate and lower plate is respectively arranged with fastener and lower fastener, upper fastening
Upper plate is fixed on backrest bottom surface by device, and lower plate is fixed on the inside of chair leg by lower fastener.
In such scheme, described torsion spring group includes a pair of torsion springs and is symmetrical arranged, and is connected among torsion spring by main shaft,
A pair of torsion springs reverse synchronous application pressure jointly.
In such scheme, described upper fastener and lower fastener are adjustable structure, and upper fastener is used
Angle between regulation upper plate and backrest, lower fastener are used to adjust the angle between lower plate and chair leg.
Principle of the present utility model is that torsion spring device is loaded into seat body, using the reset principle of torsion spring, strengthens backrest
Recovery, while plank frame can also strengthen the support to seat.
The utility model is by adopting the above-described technical solution, have the advantages that：
The utility model is simple in construction, and it is easy to make, by increasing capacitance it is possible to increase the elasticity recovery of backrest, reduces being manufactured into for seat
This, while reinforcement support can be carried out to seat, improve impact resistance and security performance.

Embodiment
In order that content of the present utility model is readily apparent understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model.
The new aero seat as shown in Fig. 1 Fig. 2 Fig. 3, includes seat body, and seat body includes chair leg 1, cushion 2
With backrest 3, return mechanism is embedded with inside seat body, and return mechanism is three stage structure, includes three pieces of supporting plates, and use
In two torsion spring groups for connecting three pieces of supporting plates；Three pieces of described supporting plates are respectively upper plate 4, the installation being arranged in backrest 3
Middle plate 5 in cushion 2, the lower plate 6 in chair leg 1, wherein two torsion spring groups are installed in the left and right ends of middle plate 5, respectively
For upper torsion spring group 7 and lower torsion spring group 10, two torsion spring groups connect and reverse the end of upper plate 4 and lower plate 6, upper plate 4 and lower plate 6 respectively
End is respectively arranged with fastener 8 and lower fastener 9, and upper plate 4 is fixed on the bottom surface of backrest 3, lower fastening by upper fastener 8
Lower plate 6 is fixed on the inner side of chair leg 1 by device 9.
In the present embodiment, described upper torsion spring group 7 and lower torsion spring group 10 include a pair of torsion springs and are symmetrical arranged, torsion spring
Centre is connected by main shaft, and a pair of torsion springs reverse synchronous application pressure jointly.
In the present embodiment, described upper fastener 8 and lower fastener 9 are adjustable structure, upper fastener 8
For adjusting the angle between upper plate 4 and backrest 3, lower fastener 9 is used to adjust the angle between lower plate 6 and chair leg 1.
Particular embodiments described above, technical problem, technical scheme and the beneficial effect solved to the utility model are entered
Further description is gone, should be understood that and the foregoing is only specific embodiment of the utility model, and do not have to
