The purpose of this utility model is that a kind of multifunctional movable bolster apparatus will be provided, make it under the situation of the version that does not change ordinary bicycle and vehicle seat, not only provide a back cushion for the cyclist, and utilize this device simultaneously to the effect that vehicle seat in parking and the cyclist in advancing play sun-shading rain-proof, accomplish one-object-many-purposes.

The purpose of this utility model is achieved in that this device is by fixed mount, tressel be connected, regulate that the bindiny mechanism of both relative positions forms.

Fixed mount is fastened on the bicycle saddle pipe, make tressel become additional clothes hanger can being at ordinary times on the level attitude of the vehicle seat back lower place by bindiny mechanism, be convenient to get on and off, overturn together to rise to and become plumbness when the handle in the bindiny mechanism drives tressel when the back upper place promotes, and fixed by the locating dowel pin in the handle with vehicle seat.

This apparatus features is can do upper and lower move and cushion that trace rotates is installed a storage tank (both can be made of one) and can be deposited foreign material such as rain gear and can utilize installation regulating mechanism, placement en-toutcas in the case to be cyclist's sun-shading rain-proof again as backrest, in the cushion back on the frame installing one on the tressel, and can make umbrella cover do upper and lower, left and right adjusting in various degree as required.Unclamp the locking piece of bindiny mechanism and tressel, tressel can rotate 90 ° to the bicycle headstock direction, utilizes cushion and storage tank that vehicle seat is covered, and the protection vehicle seat is when parking, and convenient the use avoids exposing to the sun and rain.

The utility model has the advantages that conspicuous: just can provide laborsaving, a comfortable backrest, make and be difficult for feeling fatigue in the long-term travel as long as on ordinary bicycle, set up this device back, the foreign material such as rain gear, minitype pump and small-sized recovery equipment that the while needs in can depositing in storage tank and riding for the cyclist.Can open storage tank at any time and take out rain gear or en-toutcas is installed and prevent to expose to the sun and rain, and can provide a protective cover for vehicle seat.Level attitude replaces clothes hanger as additional clothes hanger or through improving can be put into vehicle seat when not needing backrest after, accomplish one-object-many-purposes, and this apparatus structure is simple, easily manufactured, form batch manufacturing easily.Be specially adapted to woman's bicycle.
