A. is arranged with connecting rod through one end of handrail mounting bracket, be set side by side with pneumatic spring with described handrail mounting bracket, this pneumatic spring one end and described handrail mounting bracket upper end are fixed, the other end and interlinking lever end hinged.
Adopt above structure, handrail body can be rotated relative to handrail mounting bracket, during upset handrail body, is arranged on the pneumatic spring on handrail mounting bracket, the deadweight of handrail body can be made to be able to slow releasing, avoids producing and impacts.
Further, described S. A. end is provided with time delay groove, and connecting rod is provided with the mounting hole coordinated with S. A., is provided with stopper section in described mounting hole, in the described time delay groove of embedding at least partially of this stopper section.This structure can in handrail switching process, pneumatic spring is made to have certain time-delay, namely handrail fell in process, during its initial condition, can freely rotate and not limit by pneumatic spring, after turning an angle, time delay recess sidewall abuts with stopper section, promotes link rotatable, and then compression pneumatic spring, this pneumatic spring is started working, buffering is provided.
Further, described time delay channel section is fan-shaped, is positioned on S. A. excircle, and its radius is equal with the mounting hole radius on two, and described stopper section is formed by mounting hole inwall is inwardly outstanding, and its sectional area is less than the sectional area of time delay groove.This structure is easily manufactured, easily implements, and can realize coordinating of stopper section and time delay groove with simply ensureing.
Further, for reducing assembly clearance, prevent from occurring abnormal sound in handrail switching process, described S. A. is coated with lining, and this S. A. end face is provided with tapped bore, and is equipped with screw, is provided with sound insulation pad between this screw head and connecting rod.
Further, described handrail body upper end is provided with headrest, in order that when handrail body is accommodated in back of seat, does not affect the traveling comfort of back seat.
Beneficial effect:
Adopt the middle handrail for rear-row chair of automobile cushioning supportive structure of above technical scheme, its structure is simple, easy to use, utilizes the pneumatic spring with certain time-delay to provide reliable buffering for handrail switching process, when handrail body is rotated, its deadweight is able to slow releasing.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
A kind of middle handrail for rear-row chair of automobile cushioning supportive structure as shown in Figure 1, comprise handrail body 1 and the handrail mounting bracket 2 being arranged on this handrail body 1 side, wherein, the rectangular platy structure of handrail body 1, its upper end is provided with headrest 5, and this headrest 5 is positioned at the side of handrail body 1 away from back of seat; Handrail mounting bracket 2 fixes back seat backrest on the side sidewall of handrail body 1, side, described handrail body 1 lower end is provided with S. A. 11, this S. A. 11 is through handrail mounting bracket 2, handrail body 1 can be rotated relative to handrail mounting bracket 2 for pivot center with this S. A. 11, when handrail body 1 is accommodated in backrest, it keeps parallel with handrail mounting bracket 2 substantially.
The end sleeve of passing handrail mounting bracket 2 at S. A. 11 is provided with connecting rod 3, described handrail mounting bracket 2 is provided with pneumatic spring 4 away from the side of handrail body 1, cylinder barrel one end and handrail mounting bracket 2 upper end of this pneumatic spring 4 are fixed, the other end, namely its piston rod end and connecting rod 3 hinged away from the end of S. A. 11.
Described S. A. 11 is coated with lining 12 with handrail mounting bracket 2 mating part, composition graphs 3 can be found out, this S. A. 11 end face is provided with tapped bore 11b, and be equipped with screw 13, sound insulation pad 14 is provided with between this screw 13 head and connecting rod 3, to realize the installation of connecting rod 3, and axial location is carried out to it.
As shown in Figure 3, S. A. 11 is provided with time delay groove 11a in the end away from handrail body 1, and this time delay groove 11a is positioned on S. A. 11 excircle, and cross section is fan-shaped, is equivalent to arrange a boss protruded vertically in S. A. 11 end.
