The circumferentially fixed connection of locating shim is crossed, connecting screw passes through armrest rear end, locating shim and connecting substrate and connects again with strut rail screw thread
It connects.
Preferably, the locating shim includes the first positioning region and the second positioning region, first positioning region and second
Positioning region is prism；A third through-hole for extending transversely through locating shim entirety is equipped among locating shim；In the connecting substrate
Equipped with one and the first adaptable first through hole of positioning region shape；The armrest rear end has extended downwardly the first fixed plate, described
First fixed plate be equipped with one with second positioning region shape be adapted the second through-hole；It is logical that first positioning region is fastened on first
In hole, the second through-hole of handrail is set on the second positioning region；Connecting screw pass through the second through-hole of handrail, locating shim the
Three through-holes, connecting substrate first through hole be threadedly coupled with strut rail.
Preferably, the handrail lower end, which extends internally, the second fixed plate, second fixed plate is by being vertically arranged
Fixed screw handrail is fixed in seat frame.
Preferably, the strut rail includes postive stop baffle and the mounting plate that postive stop baffle both ends are arranged in；Each installation
It offsets on the inside of the outside of plate and connecting substrate；The postive stop baffle is coated on outside connecting substrate, shape and connecting substrate shape
Shape is adapted.Guarantee that strut rail will not circumferentially rotate during installation is with use.
For the ease of processing and positioning stablity, first positioning region is quadrangular.Second positioning region is four
Prism.
Preferably, the connecting substrate is welded in back frame.
The beneficial effects of the utility model are:
The step of saving assembly improves the efficiency of assembly.Connecting screw passes through armrest rear end, locating shim and connection
Substrate is directly threadedly coupled with strut rail again, and a step completes the installation between handrail and strut rail；The use of screw is also saved simultaneously.
Pass through circumferential being mounted of the first positioning region and the second positioning region realization handrail on locating shim.Locating shim
The first positioning region be fastened in the first through hole of connecting substrate, the second through-hole of handrail is set on the second positioning region, is avoided
The shaking and rotation of installation front and back.And when the loosened screw of handrail lower end, because handrail upper end is installed using car coat type, because
, although handrail lower end loosens, handrail will not still teetertotter for this.
