Technical Field

[0001] This utility model relates to the field of children's vehicle technology, and in particular to an adjustable double seat for children's vehicles. Background Technology

[0002] In daily life, strollers are being used more and more widely, and the requirements for their functionality and practicality are getting higher and higher. Currently, stroller seat structures are relatively simple, usually adjusting the backrest angle. However, this structure affects the overall size and appearance of the stroller. Strollers are large, have limited appearance, and can only be equipped with a single seat, resulting in lower comfort and failing to meet the higher usage needs of users. Therefore, there is a need for improvement. Utility Model Content

[0003] This utility model provides an adjustable double stroller seat that allows for quick adjustment of the seat angle, can accommodate two seats, and is not limited by the stroller's size. It can reduce costs and size to a certain extent, increase user comfort, and meet users' higher usage needs. It solves the technical problems of existing stroller seats, which have relatively simple structures, usually only adjustable backrest angles, resulting in low comfort, and are limited in size, large in size, and expensive, failing to meet users' higher practical needs.

[0004] The above-mentioned technical problem of this utility model is solved by the following technical solution: an adjustable double seat for a stroller, including a frame, with several detachable seats at the bottom of the frame, on which seat cushions are placed. A seat back is provided at the rear of the frame, with one end of the seat back rotatably mounted on the frame and the other end fixed to the seat. The frame is provided with an adjustment component for adjusting the position of the seat. The seat back of this utility model is composed of a single or two pieces of flexible fabric. The seat in this utility model can be detached from the frame. The adjustment component at the bottom of the frame can adjust the fore-and-aft position and angle of the seat, thereby adjusting the angle between the seat and the seat back, which is convenient for the user to adjust according to comfort. Moreover, the seat in this utility model is a double seat and can be adjusted individually. The double seat in this utility model can reduce the size of the stroller to a certain extent, and the size is not limited by the structure, allowing it to be designed as a double-seat stroller.

[0005] Preferably, the adjustment component includes mounting plates fixed to both sides of the bracket, with adjustment grooves on the mounting plates. The seat is slidably mounted between the mounting plates, and its position can be adjusted by sliding along the adjustment grooves. This invention uses four mounting plates, which are fixed to the bracket by support rods. Each mounting plate has an adjustment groove, allowing the seat to slide along the groove to adjust its angle relative to the seat back.

[0006] Preferably, the adjustment groove is an arc-shaped groove, and the center of the adjustment groove is the same point as the mounting position of the seat back. In this invention, the center of the adjustment groove is the same point as the mounting position of the seat back, so the length of the seat back will not change when adjusting the seat.

[0007] Preferably, the control assembly further includes a deep groove ball bearing slidably mounted within the control groove, with the tail end of the deep groove ball bearing fixed to the seat. The deep groove ball bearing can drive the seat to slide along the control groove.

[0008] Preferably, the control component further includes several fixing holes formed on the surface of the mounting plate, and a fixing pin that can be inserted into the fixing holes is slidably installed under the seat. When the fixing pin is inserted into the fixing hole, the seat position is fixed; when the fixing pin is disengaged from the fixing hole, the seat position can be slidably adjusted.

[0009] Preferably, the fixing holes are arranged along an arc, and the arc of the fixing hole arrangement is concentric with the regulating groove.

[0010] Preferably, a spring is provided between the fixing pin and the seat. The function of the spring is to facilitate the quick and secure insertion of the fixing pin into the fixing hole.

[0011] Preferably, the control assembly also includes a control button installed on the front side of the seat, the control button containing a brake cable connected to the fixing pin. When adjusting the seat, pressing the control button moves the inner wire of the brake cable, which pulls the fixing pin out of the fixing hole. At this time, the entire seat can slide along the control groove, thereby adjusting the angle between the seat and the seat back. When the desired position is reached, releasing the control button loosens the inner wire of the brake cable, and the fixing pin, under the action of the storage spring, inserts into the fixing hole, fixing the seat position. The control assembly also includes a control button installed on the front side of the seat, the control button containing a brake cable connected to the fixing pin.

[0012] Preferably, the stool includes a left stool panel and a right stool panel, which are assembled together by several connecting rods. The stool of this invention consists of a left stool panel, a right stool panel, and several connecting rods, and is fixed in place by bolts.

[0013] Therefore, the adjustable double seat for children's strollers of this utility model has the following advantages: the seat angle can be quickly adjusted, a double-seat stroller can be arranged, and the size of the stroller is not limited. It can reduce costs and volume to a certain extent, increase user comfort, and meet users' higher usage needs. Attached Figure Description
