Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a seat cushion with an intermediate layer foam structure. Background Art

[0002] With the development of the automotive industry, end-users are demanding more and more functional features from car seats. Currently, seat cushions are equipped with occupancy sensors to remind passengers to wear seat belts. However, the presence of these sensors prevents the seat cushion from having sufficient space for Z-axis arrangement, which in turn limits the effective installation space for the seat cushion massage airbags. Utility Model Content

[0003] In view of the above problems, the purpose of the present utility model is to provide a seat cushion with an intermediate layer foam structure, so that even if there is an occupancy sensor on the A side of the seat cushion, the massage air bag can still be arranged in a position that meets the working conditions for accurate detection, so as to overcome the shortcomings of the above-mentioned existing technology.

[0004] The utility model provides a seat cushion with an intermediate layer foam structure, including a seat, and the improvement made is that it also includes: a seat cushion foam body, an occupancy sensor, a foam intermediate layer, a massage air bag and soft foam arranged in sequence from bottom to top, the seat cushion foam body is arranged on the seat cushion position, the upper end surface of the seat cushion foam body is provided with a mounting groove for installing the occupancy sensor, the occupancy sensor is installed in the mounting groove, the foam intermediate layer is adhered to the upper end surface of the seat cushion foam body and blocks the mounting groove, the massage air bag is arranged on the upper surface of the foam intermediate layer, and the soft foam is laid on the upper surface of the massage air bag.

[0005] The beneficial effects of the utility model are as follows:

[0006] 1. This utility model solves the space and comfort issues of seat layout by adding a middle layer of foam. In a limited space, it solves the problem of insufficient space for massage air bags and occupancy sensors, improves car seat comfort, and personalizes car seat hardness.

[0007] 2. The present invention can obtain structural space for Z-direction arrangement when there is insufficient space on the A side of the seat, so that even if there is a massage air bag on the A side of the seat, the occupancy sensor can still be arranged in a position that meets the working conditions for accurate detection.

[0008] 3. The hardness and density of the middle layer foam of the utility model can be adjusted independently from the foam body. In this way, the user's comfort requirements for the seat are met, the foam hardness adjustment range is larger, and the comfort adjustment is more precise. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] By referring to the following description in conjunction with the accompanying drawings, and with a more comprehensive understanding of the present invention, other objects and results of the present invention will become more clear and easy to understand. In the accompanying drawings:

[0014] The reference numerals include: seat cushion foam body 1, occupancy sensor 2, foam middle layer 3, massage air bag 4, soft foam 5, and installation groove 6. DETAILED DESCRIPTION

[0015] See Figure 1-4 As shown, the present embodiment provides a seat cushion with an intermediate layer foam structure, comprising: a cushion foam body 1, an occupancy sensor 2, a foam intermediate layer 3, a massage air bag 4 and a soft foam 5 arranged in sequence from bottom to top, the cushion foam body 1 is arranged on the cushion position of the seat, and an installation groove 6 for installing the occupancy sensor 2 is provided on the upper end surface of the cushion foam body 1, the occupancy sensor 2 is installed in the installation groove 6, the foam intermediate layer 3 is adhered to the upper end surface of the cushion foam body 1 by gluing or double-sided tape and covers the installation groove 6, the massage air bag 4 is arranged on the upper surface of the foam intermediate layer 3, and the soft foam 5 is laid on the upper surface of the massage air bag 4. After the massage air bag 4 and the occupancy sensor 2 are arranged, the seat skin is covered as a whole.

[0016] The hardness and density of the foam intermediate layer 3 in this embodiment can be adjusted independently from the seat cushion foam body 1. In this way, the user's comfort requirements for the seat are met. Compared with the conventional foam assembly without an intermediate layer, the seat cushion foam has a larger hardness and softness adjustment range and more precise comfort adjustment.

[0017] Working principle: A foam middle layer 3 is added to the seat cushion foam body 1, so that functional structures such as the occupancy sensor 2 and the massage airbag 4 can be arranged relative to the Z direction, thereby solving the problem of insufficient space for the massage airbag and occupancy sensor within a limited space and improving the comfort of the car seat.

[0018] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
