Abstract

The utility model relates to a portable backrest chair for motorcycles, which is composed of a slide rail type supporting frame, a mounting lug, a baseplate of a backrest, a backrest, a positioning lug, a positioning screw rod, a positioning spiral handle, a positioning gear rack and a positioning supporting tube. The utility model can be arranged on the supporting frame of the rear seat of a motorcycle when used. According to different numbers, body types and driving poses of people on the motorcycle, the utility model can conveniently and fast move the front position and the rear position of the backrest and change the slope angle of the backrest to cause a driver's gravity to evenly disperse on every part of the motorcycle. Thus, the driver's fatigue is radically relieved and driving safety is ensured. The utility model has the advantage of reasonable design, and the existing soft seats of the motorcycle can not be damaged when the backrest moves.

Description

Mobile chair of motorcycle

The utility model relates to the seat of motor bike, specifically is meant a kind of portable motor bike chair.

When driving motor bike, people's center of gravity concentrates on the pyramidal place, and after the time grown, the uncomfortable sensation of aching all appearred in people's whole waist, back and neck, influence safe driving and drives a vehicle.Notification number is that CN2111246U's " motor bike backrest " and notification number is CN2122105U " motor bike dual-purpose safe backrest ", though can alleviate driver fatigue and discomfort, but move the back because their backrest all can not be gone forward at the seat, therefore the position of backrest can not be adjusted according to the quantity of passenger on the motor bike, so that of non-ideal use when two people take, directly influence promoting the use of of they.

The purpose of this utility model is that a kind of afterwards mobile very comfortable portable motor bike chair of taking of can going forward at the seat is provided.

Solution of the present utility model is as follows.It has a slide rail type support, a left side, slide rail type support top, right both sides all have the chute of level, a left side, slide rail type support bottom, the below of right both sides all has at least two mounting lugs that are connected mutually with the slide rail type support, all have mounting hole on the mounting lug, slide rail type support top has backrest baseplate and the backrest that connects together, a left side, backrest baseplate bottom, right down either side all has two positioning tabs that are connected mutually with the backrest baseplate, all have the positioning screw perforation on the positioning tab, from a left side, slide rail type support top, each sliding positioning screw that stretches out positioning screw perforation on two two positioning tabs that pass the same side respectively in the chute of right both sides, the positioning screw end all is connected with the setting screw handle that overlays positioning tab, backrest is positioned at backrest baseplate the place ahead, live mutually in selling with backrest baseplate front end and connect in the bottom of backrest, left side at the backrest rear, right both sides, respectively have a radicle and backrest pin bonded assembly alive mutually location tooth bar, the location rack rear has downward positioning tooth, on a backrest baseplate left side, right both sides, all be fixed with the positioning supports pipe of the top that tiltedly reaches out, the rear portion of location tooth bar puts in the positioning supports pipe, and the clamping and locating mutually of the top-side of its positioning tooth and positioning supports pipe.

The utility model with said structure in use, be installed on the top of flapper-bracket, the mounting lug of its both sides, slide rail type support lower end is linked to each other with the connecting screw of seat support both sides, the existing back of motor bike respectively, thereby the utility model and motor bike are firmly linked together.Before taking motor bike, unclamp four setting screw handles on the positioning screw, (or back) direction is touched moving backrest and backrest baseplate with have gentle hands before motor bike, make positioning screw along the horizontal concrete chute on the slide rail type support forward (or backward) move, thereby regulate backrest and the forward and backward position of backrest baseplate above flapper-bracket arbitrarily.If rider only has only chaufeur one people, then backrest and backrest baseplate are shifted to the appropriate location of flapper-bracket front portion; If rider has two people, then backrest and backrest baseplate are shifted to the appropriate location at flapper-bracket rear portion.After reserve the shift position of backrest and backrest baseplate, just can tighten up four setting screw handles, make backrest and backrest baseplate on the slide rail type support, fixedly positioning.Next, regulate the top-side clamping mutually of different gear teeth and positioning supports pipe on the tooth bar of location again, with regard to the angle of inclination of scalable backrest, to satisfy the needs of rider.By above-mentioned adjusting, just can make the chaufeur or the person of taking when riding motor bike, lean against on the backrest, obtain the failure-free sense of security and comfort easily.

This portable motor bike chair is applicable to any motor bike that its slide rail type support can be installed.It can be according to the different number of rider, different build and different vehicle driving postures, the angle of inclination of convenient moving backrest position promptly and conversion backrest, make the gravity of chaufeur be scattered in each position equably, thereby can fundamentally alleviate driver fatigue, guarantee driving safety.This device is reasonable in design, can not damage the existing soft seat of motor bike when backrest moves.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is that a kind of concrete structure of the present utility model is installed in the scheme drawing on the flapper-bracket support;

Fig. 2 is of the present utility model about the integral structure figure of member composition from state among Fig. 1;

Fig. 3 is the amplification assumption diagram of local slide rail type support, positioning screw and setting screw handle among Fig. 2.

Reference numeral among the above-mentioned figure is: 1, slide rail type support, 2, chute, 3, mounting lug, 4, the backrest baseplate, 5, backrest, 6, positioning tab, 7, positioning screw, 8, the setting screw handle, 9, location tooth bar, 10, the positioning supports pipe, 11, flapper-bracket support connecting screw.

Referring to Fig. 1 and Fig. 2, in this embodiment, the slide rail type support is to be connected and composed by some different directions and difform rod member and ornamental trimming with pattern.Referring to Fig. 2 and Fig. 3, the both sides, top of slide rail type support (1) are the steel square tube, all have chute (2) in the outside of two square tubes, and chute (2) two is big slightly, the head that is beneficial to positioning screw (7) enters in the square tube thus, but head can outwards not deviate from chute (2) again.
