Abstract
The utility model relates to a chair having an automatic slowly tipping-up seat, comprising a chair back (1), a seat cushion (3), chair legs (4) and a seat cushion automatic folding device, characterized in that a damping air spring (5) is situated in the inner cavity of the seat cushion (3), one end of the air spring (5) is fixed with the frame of the seat cushion (3), and the other end is fixed with the rotating shaft (7) of the seat cushion. When the seat cushion is automatically folded, the utility model is slowly turned over back and folded to a tipping-up condition under the damping action of the air spring without any impact noise.
Description
A kind of cinema, theater of being used for of the utility model design, public's seats such as assembly hall, specifically a kind of seat cushion can delay the seat that stands up automatically.
At present, the seat that is widely used in public situation such as cinema, theater, assembly hall puts down seat cushion in use, and in that the time spent does not stand up, packs up, enlarge passage, evacuate in order to spectators, it is manual generally putting down seat cushion, and pack up seat cushion generally is by the setting of center of gravity or the setting of torsion spring, be automatic mostly, its ubiquitous defective is that seat cushion returns and turns over excessive velocities, can send impact sound (noise) when striking the chair back or other limited blocks, both influenced spectators' auditory effect, also what can cause damage to seat to time one length.
The purpose of this utility model is with regard to being at the present situation of above-mentioned prior art and provide a kind of seat cushion can delay the seat that stands up automatically.
The purpose of this utility model is achieved in that seat cushion can delay the seat that stands up automatically and comprise that the chair back, seat cushion, chair pin and seat cushion pack up device automatically, one air spring that has damping is positioned at the seat cushion inner chamber, one end and the cushion frame of this air spring fix, and the other end and seat cushion rotating shaft fix.
Compared with prior art, when the utility model is packed up automatically at seat cushion, under the damping action of air spring, return lentamente to turn over and pack up, no longer produce impact noise until the state of standing up.
Description of drawings:
Fig. 1 is the side view of the utility model embodiment (seat cushion stand up state, analyse and observe).
Fig. 2 is the front view of the utility model embodiment (seat cushion stand up state, broken section).
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As Fig. 1, shown in Figure 2, be one to realize the embodiment that seat is packed up automatically by torsion spring (8), comprise the chair back (1), handrail (2), seat cushion (3) and chair pin (4) and seat cushion are packed up device automatically, the structure that seat cushion is packed up device automatically is: seat cushion (3) is fixed on the chair pin (4) by its rotating shaft (7), can rotate around its rotating shaft (7), torsion spring (8) one ends are fixed on seat cushion (3) framework, the other end is fixed in the rotating shaft (7), one air spring (5) that has damping is positioned at seat cushion (3) inner chamber, one end of this air spring (5) and seat cushion (3) framework fix, the other end and seat cushion rotating shaft (7) fix, and embodiment is for being fixed on the support (6) that is fixed as one with rotating shaft (7) among the figure.
When spectators take a seat, to seat cushion (3) apply external force make seat cushion (3) from the state of standing up to setting level state, torsion spring this moment (8) turns over an angle, accumulation of energy, simultaneously air spring (5) also is in compressive state, and when spectators stand up, external force is cancelled, the restoring force of torsion spring (8) is packed up seat cushion (3), and air spring (5) works simultaneously, under both cooperated, seat cushion (3) went to the state of standing up around its rotating shaft (7) from flat condition lentamente, thereby reached slow purpose of packing up.
Feature of the present utility model mainly is the setting of damping air spring (5); packing up device automatically and can adopt existing various structure as for seat; accompanying drawing embodiment only provides a kind of scheme of packing up automatically wherein, and this does not limit protection domain of the present utility model.
