This creation is related to bicycle seat cushions, and in particular to a bicycle seat body having an auxiliary function sheet.

Generally, the bicycle seat body mainly comprises an elastic body, a rigid bottom case, and a surface layer. The elastic system is made of a foamed material, such as polyurethane (PU), ethylene-vinyl acetate (EVA) or polyethylene (PE). To provide modest cushioning and support. The bottom case is disposed at the bottom of the elastic body to support the entire seat body and is coupled to the bicycle seat post by other members. The skin layer (eg, synthetic plastic skin) covers the top and side edges of the elastomer for contact with the rider.

In order to prevent the rider from being too smooth on the surface of the surface to ride on the bicycle seat cushion, some bicycle seat cushion bodies will have a plurality of bumps on the top, or the surface of the surface layer will adhere to the anti-slip sheet to increase the bicycle seat. The friction between the pad body and the rider, in turn, achieves a non-slip effect. However, the bicycle seat cushion body with the bumps on the top is easy for the rider to feel uncomfortable, and the anti-slip sheet is adhered to the surface of the bicycle seat cushion body, which may cause the slippery sheet to fall off easily.

In view of the above-mentioned shortcomings, the main purpose of the present invention is to provide a bicycle seat body having an auxiliary function piece, which has the anti-slip effect and is comfortable to ride, and can avoid the problem that the anti-slip piece falls off.

Thereby, the surface layer can achieve a moderate anti-slip effect by having the recessed area, and the bicycle seat body of the present invention is more comfortable in riding than the conventional bicycle seat body having a bump on the top. The auxiliary function sheet can be an anti-slip sheet, so that the bicycle seat body has a better anti-slip effect, and the anti-slip sheet is less likely to fall off due to being embedded in the recessed portion of the surface layer (or further adhered to the recessed area). However, the auxiliary function sheet is not limited to the anti-slip sheet, and may be a cooling sheet, a shock absorbing sheet, or a pattern sheet having a specific pattern indicating function (for example, indicating a trademark), which may be provided as needed.

Preferably, the auxiliary function sheet has an active surface which is exposed on the contact surface of the surface layer and is located in the recessed area. That is, the user can see the active surface of the auxiliary function sheet on the contact surface of the surface layer, but the active surface is not flush with or higher than the contact surface seen by the user, but is slightly lower than The contact surface. Thereby, the auxiliary function sheet is less likely to fall off due to the user rubbing the contact surface of the surface layer.
