[0031] The following is combined with Figures 1-5 The technical solution provided by this utility model will be described in more detail.

[0032] Example 1:

[0033] See Figures 1-5 As shown, the vehicle seat cushion provided by this utility model includes a seat cushion body 1 and a backrest 2. The backrest 2 includes a curved panel 21 and a fixing part 22, wherein: the curved panel 21 and the fixing part 22 are fixedly connected, the fixing part 22 is fixedly connected to the seat cushion body 1, the curved panel 21 is located on the side of the seat cushion body 1 away from the front of the vehicle, the shape of the curved panel 21 conforms to the physiological curve of the human waist and hips, and the curved panel 21 can fit and support the rider's waist.

[0034] The seat body 1 includes a seat base plate and a pad fixed on the seat base plate. The seat base plate provides support and fixation, while the pad is in direct contact with the rider. As this is an existing technical solution, it will not be described in detail here.

[0035] The seat body 1 of this embodiment adopts a structure that conforms to the curve of the human buttocks, which can evenly distribute the pressure on the buttocks, reduce local pressure, and prevent stuffiness during long-term riding.

[0036] In this embodiment, the curved panel 21 of the backrest 2 is designed based on the physiological curve of the human waist, after extensive measurement and analysis of human data, and can closely fit the waist to provide all-round support. The backrest 2 adopts a multi-layer composite structure. The outer layer is soft and skin-friendly, providing a comfortable touch; the middle layer is an elastic support material, such as memory foam or special elastic sponge, which can adapt to the deformation according to the pressure on the waist and accurately support various parts of the waist; the inner layer is a high-strength support frame to maintain the shape of the backrest 2 and provide stable support.

[0037] In this embodiment, the vehicle seat cushion has a backrest 2 that is stably fixed to the seat body 1. The curved panel 21 conforms to the physiological curves of the human waist and hips. The curved panel 21 is located on the side of the seat body 1 away from the front of the vehicle. When the rider sits on the seat body 1, the curved panel 21 can precisely fit the waist. During riding, the backrest 2 will adaptively adjust according to changes in waist pressure, distributing the pressure on the waist and reducing the burden on the lumbar spine. At the same time, the seat body 1 evenly distributes the pressure on the hips, making the human sitting posture more stable and comfortable.

[0038] As an optional implementation, see Figures 1-3 As shown, the curved panel 21 of this embodiment includes an integrally formed support portion 211 and a relief portion 212, wherein: the relief portion 212 is connected to the lower part of the support portion 211, and there is a smooth transition between the relief portion 212 and the support portion 211. The relief portion 212 is a curved surface structure that protrudes in the direction away from the front of the vehicle, and the support portion 211 is a curved surface structure that protrudes in the direction of the front of the vehicle. The support portion 211 is used to fit and support the rider's waist.

[0039] The yielding part 212 is designed to conform to the curve of the rider's hips and the curve at the connection between the hips and waist, while the support part 211 conforms to the curve of the rider's waist. (See also...) Figure 2 As shown, when the cyclist sits on the saddle, the saddle-shaped relief section 212 provides space for the buttocks, while the support section 211 provides close support for the lower back, relieving fatigue. The curved panel 21 adaptively adjusts according to changes in lumbar pressure, distributing the pressure on the lower back and reducing the burden on the lumbar spine. At the same time, the saddle body 1 evenly distributes pressure on the buttocks, making the sitting posture more stable and comfortable.

[0040] As an optional implementation, see Figure 4 and Figure 5 As shown, the fixing part 22 is a plate structure, and the fixing part 22 and the curved panel 21 are integrally formed.

[0041] The above structure eliminates the need for additional connecting structures between the fixing part 22 and the curved panel 21, resulting in a more stable structure.

[0042] As an optional implementation, in this embodiment, the distance between the curved panel 21 and the seat cushion body 1 is adjustable. This allows the user to fine-tune the angle of the backrest 2 according to their own sitting posture habits, further optimizing lumbar support and achieving optimal comfort.

[0043] As an optional implementation, see Figure 4 and Figure 5 As shown, the fixing part 22 in this embodiment is provided with an adjustment hole 3. The adjustment hole 3 is an elongated hole that extends along the length of the seat body 1. The locking member 4 passes through the corresponding position of the adjustment hole 3 to thread the fixing part 22 and the seat body 1 together.

[0044] The locking component 4 can be a common connecting component such as a screw or bolt. When it is necessary to adjust the position of the backrest 2, loosen the locking component 4, and the backrest 2 can move along the direction closer to or away from the front of the vehicle, that is, the backrest 2 moves along the length of the seat cushion body 1. After adjusting the position of the backrest 2, tighten the locking component 4 again.

[0045] The aforementioned structure allows the backrest 2 to be adjusted forward and backward to accommodate users of different heights and body types, thus expanding the product's applicability. It enables consumers to adjust the position of the backrest 2 according to their own needs, allowing for better relaxation of the lumbar muscles, maintaining the natural physiological curvature of the lumbar region, and reducing fatigue.

[0046] As an optional implementation, see Figure 4 and Figure 5 As shown, there are two or more adjustment holes 3, and all adjustment holes 3 are arranged in parallel.

[0047] The above structure, in which the adjustment hole 3 cooperates with the corresponding locking part 4, realizes multiple positioning of the fixing part 22 and the seat cushion body 1, and improves the stability of the connection structure between the backrest 2 and the seat cushion body 1.

[0048] As an optional implementation, see Figure 5 As shown, the fixing part 22 is attached to the bottom of the seat body 1, and there is a non-zero angle α between the fixing part 22 and the horizontal plane. The value of the non-zero angle α is in the range of 1-10°.

[0049] Preferably, the non-zero included angle α is 5°, but this angle is not limited. The tilt angle of the fixing part 22 in this embodiment is more in line with the curvature of the seat body 1 (seat base plate), which can reduce the inertial impact during braking.

[0050] As an optional implementation, one of the seat cushion body 1 and the fixing part 22 is provided with a protrusion 5, and the other is provided with a groove 6. The protrusion 5 is inserted into the groove 6, thereby pre-positioning the fixing part 22 and the seat cushion body 1.

[0051] See Figure 4 and Figure 5 As shown, the seat cushion body 1 is provided with a protrusion 5, and the fixing part 22 is formed with a groove 6. The groove 6 extends in the direction away from the seat cushion body 1. The protrusion 5 is inserted into the groove 6, which can play the role of pre-positioning the fixing part 22 and the seat cushion body 1. After the fixing part 22 and the seat cushion body 1 are pre-positioned, the locking part 4 is used to fasten the fixing part 22 and the seat cushion body 1, which is convenient for installation.

[0052] It should be noted that the size of the groove 6 is larger than the size of the protrusion 5, so as to allow space for the backrest 2 to be adjusted forward and backward. Specifically, the groove 6 provides a moving distance for the protrusion 5 along the length of the adjustment hole 3, so as to prevent the mating structure of the groove 6 and the protrusion 5 from affecting the forward and backward adjustment of the backrest 2.

[0053] As an optional implementation, see Figures 1-5 As shown, the fixing part 22 is a bent plate structure, thereby fixing the fixing part 22 to the bottom of the seat cushion body 1, and the curved panel 21 is located on the side of the seat cushion body 1 away from the front of the vehicle; see also Figure 4 and Figure 5 As shown, a reinforcing rib 7 is provided at the connection position between the fixing part 22 and the curved panel 21, and / or at the bending position of the fixing part 22.

[0054] The reinforcing rib 7 and the backrest 2 are integrally formed, which can improve the structural strength of the backrest 2, especially at the connection between the curved panel 21 and the fixing part 22 and at the bending position of the fixing part 22, to prevent structural damage caused by stress concentration.
