Description

Technical Field

[0001] The present invention relates to the technical field of children's stroller seats, and particularly to a foldable seat. Background Art

[0002] Due to the limited rotation angle of the seat board of the existing children's stroller seats, it is difficult to adapt to different frames, thus reducing the universality of the device. For this reason, we provide a foldable seat. After the seat is folded, it can rotate 360 degrees around the card seat, avoiding the need for a specific angle when the device is combined with different strollers during folding. Summary of the Invention

[0003] To solve the problem that the existing children's seats in the above background art are difficult to adapt to different frames, the present invention provides a foldable seat.

[0004] The present invention is implemented by the following technical solutions: A foldable seat includes a seat board. Two groups of seat board connecting flat irons are symmetrically and fixedly connected to the seat board. A seat board upper segmented piece is arranged outside the seat board connecting flat iron. An armrest iron piece is arranged outside the seat board upper segmented piece. An armrest retaining pin is arranged on the armrest iron piece. An armrest retaining pin spring is added to the armrest retaining pin. An articulating tooth is arranged outside the armrest iron piece. An articulating tooth spring is arranged outside the articulating tooth. A backrest joint is arranged outside the articulating tooth. A card seat is arranged outside the backrest joint. A card seat cover is added to the card seat. An activity button assembly is also arranged on the card seat.

[0005] As a further improvement of the above solution, the activity button assembly includes a card seat button movably connected to the card seat. A retaining pin is arranged on the card seat. A retaining pin spring is added between the retaining pin and the card seat. A memory pin is also arranged on the card seat. A memory pin spring is added between the memory pin and the card seat.

[0006] As a further improvement of the above solution, an armrest seat is fixedly connected to the armrest iron piece. An armrest is installed between the two armrest seats.

[0007] As a further improvement of the above solution, the number of the articulating tooth springs is three and they are circumferentially distributed equidistantly around the center of the articulating tooth outside the articulating tooth.

[0008] As a further improvement of the above solution, grooves are opened at the positions corresponding to the articulating tooth springs outside the articulating tooth.

[0009] As a further improvement of the above solution, the same backrest is installed on the two backrest joints. A buckle is installed on the backrest.

[0010] As a further improvement of the above solution, a backrest segment pin is provided on the backrest joint, and a segment pin spring is added to the backrest segment pin.

[0011] As a further improvement of the above solution, a card slot is provided at the edge of the armrest iron sheet.

[0012] As a further improvement of the above solution, the maximum angle for the seat board to rotate around the seat holder is 360°.

[0013] As a further improvement of the above solution, a leg rest is movably connected to the seat board.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] In the present invention, when the backrest is closed and approaches the seat board, and the angle must be less than 20 degrees to drive the seat board out of position (if there is a young child on the seat, it is impossible to fold to this angle), therefore, the operation of the second button is not required during the process of closing the seat backrest. When the seat is closed to the folded state, all the pin locks are in the unlocked state, and the entire folded seat can rotate 360° clockwise or counterclockwise around the seat holder of the seat, so as to facilitate its adaptation to various vehicle frames, thereby improving the practicability of the device.

[0021] Next, in combination with the drawings and specific embodiments, the present invention will be further described. It should be noted that on the premise of no conflict, the following described embodiments or technical features can be combined with each other arbitrarily to form new embodiments.

[0022] Embodiment 1:

[0023] Please refer to Figures 1-3 , a foldable seat in this embodiment includes a seat board 1. Two groups of seat board connecting flat irons 2 are symmetrically and fixedly connected to the seat board 1. A seat board upper segmented piece 3 is arranged outside the seat board connecting flat iron 2. An armrest iron piece 4 is arranged outside the seat board upper segmented piece 3. An armrest retaining pin 5 is arranged on the armrest iron piece 4. An armrest retaining pin spring 6 is added to the armrest retaining pin 5. A joint tooth 7 is arranged outside the armrest iron piece 4. A joint tooth spring 8 is arranged outside the joint tooth 7. A backrest joint 9 is arranged outside the joint tooth 7. A card seat 10 is arranged outside the backrest joint 9. A card seat cover 11 is added to the card seat 10. An activity button assembly is also arranged on the card seat 10. An armrest seat 17 is fixedly connected to the armrest iron piece 4. An armrest 18 is installed between the two armrest seats 17. The number of the joint tooth springs 8 is three and they are circumferentially and equidistantly distributed around the center of the joint tooth 7 outside the joint tooth 7. Grooves are opened at the positions corresponding to the joint tooth springs 8 outside the joint tooth 7. The same backrest 19 is installed on the two backrest joints 9. A buckle 20 is installed on the backrest 19. A backrest segmented retaining pin 21 is arranged on the backrest joint 9. A segmented retaining pin spring 22 is added to the backrest segmented retaining pin 21. A card slot is arranged at the edge of the armrest iron piece 4. The maximum rotation angle of the seat board 1 around the card seat 10 is 360°.

[0024] The activity button assembly includes a card seat button 12 movably connected to the card seat 10. A retaining pin 13 is arranged on the card seat 10. A retaining pin spring 14 is added between the retaining pin 13 and the card seat 10. A memory pin 15 is also arranged on the card seat 10. A memory pin spring 16 is added between the memory pin 15 and the card seat 10.

[0025] The implementation principle of a foldable seat in the embodiment of this application is as follows: When the backrest 19 is driven by the buckle 20 to be folded close to the armrest 18, the backrest joint 9 will drive the armrest retaining pin 5 to be displaced. When the backrest 19 is close to the seat board 1 (the included angle between the backrest and the seat board is less than 20 degrees), it will drive the seat board 1 to be displaced. At this time, the seat board 1 will be in a folded state. The entire seat can rotate 360° clockwise or counterclockwise around the card seat 10, so as to facilitate its adaptation to various vehicle frames, thereby improving the practicability of the device. When the backrest 19 is pulled by the buckle 20 to be unfolded to a certain angle, the backrest segmented retaining pin 21 will snap into the card slot on the armrest iron piece 4. As the backrest 19 continues to unfold, it can automatically drive the armrest 18 to open. When the backrest segmented retaining pin 21 snaps into the first card slot on the seat board upper segmented piece 3, at this time the armrest retaining pin 5 will be locked at the same time, so as to complete the unfolding of the seat.

[0026] Embodiment 2:

[0027] On the basis of Embodiment 1, a further improvement in this embodiment is that a leg rest 23 is movably connected to the seat board 1, which can provide support for the legs.

[0028] The above embodiments are only preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited thereby. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
