Abstract

A continuously adjustable stroller reclining mechanism includes a belt binder affixed to the backrest of the stroller seat. Two ends of a belt are affixed to the two supporting rods of the stroller. By using the belt binder, one can release the belt to adjust the inclination angle of the backrest to a desirable angle.

Claims

1. A continuously adjustable stroller inclination mechanism, which is applicable to a stroller that includes a backrest having a back plate and two supporting rods, a belt binder being disposed to the back plate and two ends of a belt being affixed to the two supporting rods, the belt binder comprising:

a main body having a positioning plate and a front plate, the positioning plate and the front plate forming a retaining space therebetween;

a pivotal shaft pivotally disposed in the retaining space of the main body, the pivotal shaft having an elastic element and a contact surface on the surface of the pivotal shaft; and

at least a belt, which penetrates the retaining space and is gripped between the contact surface of the pivotal shaft and the positioning plate of the main body;

whereby the pivotal shaft can be rotated to release the tightly contacted belt from the contact surface, so as to continuously adjust the inclination angle of the backrest to any desirable angle.

2. The mechanism of claim 1, wherein the main body further comprises two side plates, the pivotal shaft being pivotally connected therewith via a riveting pillar.

3. The mechanism of claim 1, wherein the contact surface of the pivotal shaft comprises a plurality of tilted protrusive teeth.

4. The mechanism of claim 1, wherein the other end of the pivotal shaft comprises a compressive portion protrusively formed thereon, the surface of the compressive portion comprising a plurality of horizontal humps.

5. The mechanism of claim 1, wherein the elastic element of the pivotal shaft comprises a spring.

6. The mechanism of claim 1, wherein a trench is formed on the main body and a positioning groove is formed on the pivotal shaft, thereby locking one end of the elastic element in the trench and positioning the other end of the elastic element in the positioning groove.

7. The mechanism of claim 1, wherein a plurality of holes is formed on the positioning plate of the main body, thereby riveting the mechanism to the backrest of the seat.
