Embodiment 1

[0047] Such as Figure 1 to Figure 5 As shown, the present invention discloses a foldable headrest, including a headrest body 1 and a folding mechanism;

[0048] The folding mechanism includes an upper bracket 2, a lower bracket 3, an unlocking shaft 6 and a locking shaft 7;

[0049] Both the upper bracket 2 and the lower bracket 3 are U-shaped brackets that are composed of a rear end plate and two side plates and form a groove between the two side plates, the lower end of the upper bracket 2 is connected to the The upper end of the lower bracket 3 is rotatably connected through the main shaft 4 passing through the side plate, and the main torsion spring 5 located in the groove cavity is sleeved on the main shaft 4, and the two torsion legs of the main torsion spring 5 are respectively Connecting the upper bracket 2 and the lower bracket 3, so that: the upper bracket 2 tends to rotate around the main shaft 4 from the expansion angle to Folding angle, wherein, when the foldab...

Embodiment 2

[0066] On the basis of the first embodiment above, the second embodiment also adopts the following preferred structure:

[0067] see Figure 4 and Figure 5 , the rear locking slot 3a is composed of a connected arc surface slot 3a1 and an arc support slot 3a2, and the arc support slot 3a2 is located at the rear and lower side of the arc slot 3a1; at the deployment angle Next, the locking shaft 7 can rotate around the unlocking shaft 6 and enter the arc-shaped slot 3a1 of the rear-end locking slot 3a, and the upper end of the vertical line V passes through the arc-shaped slot 3a1, vertically The lower end of the line V only passes through the arc surface support groove 3a2, wherein the vertical line V is: when the locking shaft 7 enters the arc surface engaging groove 3a1, the axis of the main shaft 4 and the lock a perpendicular to the plane S common to the axes of the shafts 7 and which passes through the axes of said locking shafts 7;

[0068] And, the rear end plate 3-2 ...

Embodiment 3

[0071] On the basis of the above-mentioned embodiment 1 or embodiment 2, this embodiment 3 also adopts the following preferred structure:

[0072] The headrest body 1 is provided with a front cover 1-1, a back cover 1-2, a foam skeleton 1-3 and a foam body 1-4; the front cover 1-1 and the back cover 1-2 are combined to form a The hollow inner cavity of the headrest body 1, and the upper part of the front cover 1-1 is provided with a window 1-1a, and the side plate avoidance groove 1a is arranged at the lower part of the front cover 1-1; Both the foam skeleton 1-3 and the foam body 1-4 are located in the hollow cavity, and the lower end of the foam skeleton 1-3 is fixedly connected with the upper support 2; the foam body 1-4 fixed on the foam frame 1-3 and exposed at the window 1-1a of the front cover 1-1; the upper bracket 2 is fixedly connected with the front cover 1-1 and the rear cover 1-2 by screws .

[0073] Thereby, the present invention centrally arranges the movable ...

Abstract

The invention discloses a foldable headrest which comprises a headrest body and a folding mechanism. The folding mechanism comprises an upper bracket, a lower bracket, an unlocking rotating shaft anda locking shaft. The headrest body is provided with a hollow inner cavity, and a side plate receding groove is formed in the bottom of the front end face of the headrest body. The folding mechanism iscontained in a hollow inner cavity of the headrest body, the upper support is connected with the headrest body, and the lower end of the lower support extends out of the bottom face of the headrest body to be used for being connected with a seat backrest. At the folding angle, the two side plates of the lower support are contained in the side plate receding grooves. According to the foldable headrest, on the premise that reliable unfolding and folding and enough strength are ensured, the folding mechanism is arranged in the headrest body, overturning folding close to 180 degrees can be achieved so that the headrest body can be tightly attached to a seat backrest to the maximum extent, the headrest body with the small overall thickness can be contained in a gap between the folded seat backrest and a cushion, and the size of the seat after double folding of the headrest and the backrest can be reduced to the maximum extent.

Description

technical field [0001] The invention relates to a headrest of a car seat, in particular to a foldable headrest. Background technique [0002] Headrest is a necessary component to ensure the comfort and safety of the occupant on the car seat, but the non-foldable headrest will also hinder the driver's rear view. Therefore, in the prior art, the foldable headrest The pillow is applied to the car seat, so that when the car seat is unoccupied, the headrest can be folded to improve the rear view of the driver. And, for the car seats in the middle row and the rear row, the backrest of the car seat is often turned and folded on the cushion to increase the trunk space of the car, and by folding the headrest, it can be further improved. Reduce the space occupied by the folded car seat to further increase the trunk space of the car. [0003] In the existing folding headrests, the headrest body is connected to the backrest of the car seat through a folding mechanism. In the backrest...
