Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology and relates to an automotive seat with a mechanical massage protection structure. Background Technology

[0002] Adding mechanical massage features to existing car seats requires the massage heads to extend when in use and retract when not in use. To ensure passengers don't feel any discomfort when the massage is off, the massage heads should be lower than the seat surface. To ensure that heavier passengers don't feel any discomfort when leaning against the seat back, the massage heads need to retract a certain distance from the foam surface. To ensure the effectiveness of the massage, the foam needs to be completely hollowed out in the chair. However, in this state, passengers will feel a hollowness in the seat surface due to the hollowed-out foam, affecting comfort. Furthermore, because of the extension and retraction requirements of the massage heads, the foam needs to be hollowed out; during extension and retraction, the massage heads need to pass through the pores in the foam, and the foam material makes it susceptible to friction, which can damage the foam. Summary of the Invention

[0003] In view of the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a car seat with a mechanical massage protection structure. By adopting a specific structure and a protective cover made of rubber material with a certain hardness, the seat surface is supported to a certain extent, so that passengers will not feel the hollow feeling of the seat surface caused by the foam, thus maximizing the riding comfort; at the same time, it solves the problem that the mechanical massage head is prone to damaging the foam during the extension and retraction process.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A car seat with a mechanical massage protection structure includes a seat body, which includes a backrest and a seat cushion. The backrest includes a backrest cover, a core soft foam, a foam body, a ventilation bag, and a massage mechanism arranged sequentially. The ventilation bag, foam body, and core soft foam have clearance holes machined at positions opposite to the massage heads of the massage mechanism. An improvement is the inclusion of a rubber protective cover that penetrates the clearance holes in the ventilation bag, foam body, and core soft foam, with its top surface contacting the backrest cover. The rubber protective cover is made of an elastic material and includes a barrel-shaped through-section and an overlapping ring disposed around the opening end of the barrel-shaped through-section. The top surface of the closed end of the barrel-shaped through-section is an arc surface. The periphery of the arc surface is connected to the outward-turned ring edge around the periphery of the barrel-shaped through-section to form a whole. The height of the barrel-shaped through-section is adapted to the thickness of the foam body and the ventilation bag. The barrel-shaped through-section and the ventilation bag are interference-fitted. The overlapping ring overlaps with the back of the ventilation bag. The connection between the barrel-shaped through-section and the outward-turned ring edge is used to overlap with the foam body. The connection between the arc surface and the outward-turned ring edge is used to overlap with the core soft foam. The highest point of the arc surface is connected to the backrest cover. The massage head of the massage mechanism is located inside the barrel-shaped through-section and performs ejection or retraction actions inside the barrel-shaped through-section.

[0006] As a preferred embodiment of this invention, the rubber protective cover is made of EPDM or TPE material.

[0007] As a preferred embodiment of this invention, the rubber protective cover penetrates the ventilation bag, the foam body, the core soft foam, and connects to the massage mechanism.

[0008] As a preferred embodiment of this invention, the TPE is selected from either TPU or TPS.

[0009] Advantages and beneficial effects of this utility model:

[0010] (1) The car seat provided by this utility model is equipped with a rubber protective cover. Through a specific structure and a rubber material with a certain hardness, the protective cover provides a certain support to the seat surface, so that passengers will not feel the hollowness of the seat surface caused by the foam, thus maximizing the comfort of the ride. At the same time, the mechanical massage head is set inside the rubber protective cover. It performs the pushing or retracting action in the barrel-shaped through part, and will not directly rub against the foam surface, thus solving the problem that the mechanical massage head is easy to damage the foam during the extension and retraction process.

[0011] (2) The rubber protective cover of this utility model is made of elastic material. Through the special design of its structure, it can provide support while improving comfort and avoiding the feeling of foreign objects when leaning on it normally. Moreover, the reasonable selection and design of the structure and material gives it good resilience performance. Attached Figure Description

[0021] like Figures 1 to 5As shown, this embodiment provides a car seat with a mechanical massage protection structure, including a seat body. The seat body includes a backrest A and a seat cushion B. The backrest A includes a backrest cover 1, a core soft foam 2, a foam body 3, a ventilation bag 4, and a massage mechanism 5 arranged sequentially. The ventilation bag 4, the foam body 3, and the core soft foam 2 have clearance holes machined at positions opposite to the massage heads 51 of the massage mechanism 5. An improvement is the inclusion of a rubber protective cover 6. The rubber protective cover 6 penetrates the clearance holes of the ventilation bag 4, the foam body 3, and the core soft foam 2, and its top surface contacts the backrest cover 1. The rubber protective cover 6 is made of an elastic material and includes a barrel-shaped through-hole 61 and an overlapping ring 62 disposed around the opening end of the barrel-shaped through-hole. The top surface of the closed end of the barrel-shaped through-section is an arc surface 64. The periphery of the arc surface is connected to the outward-turned ring edge 63 around the barrel-shaped through-section to form a whole. The height of the barrel-shaped through-section 61 is adapted to (basically the same as) the thickness of the foam body 3 and the ventilation bag 4. The barrel-shaped through-section 61 and the ventilation bag 4 are interference fit. The overlapping ring 62 overlaps with the back of the ventilation bag 4. The connection between the barrel-shaped through-section 61 and the outward-turned ring edge 63 is used to overlap with the foam body 3. The connection between the arc surface 64 and the outward-turned ring edge 63 is used to overlap with the core soft foam 2. The highest point of the arc surface 64 is connected to the backrest cover 1. The massage head 51 of the massage mechanism 5 is located inside the barrel-shaped through-section 61 and performs an ejection or retraction action inside the barrel-shaped through-section 61.

[0022] In this embodiment, the rubber protective cover is made of EPDM (ethylene propylene diene monomer) or TPE (thermoplastic elastomer) material; the TPE (thermoplastic elastomer) is selected from either TPU (thermoplastic polyurethane elastomer) or TPS (thermoplastic styrene elastomer).

[0023] In this embodiment, the rubber protective cover penetrates the ventilation bag, the foam body, the core soft foam, and connects to the massage mechanism, and the rubber protective cover and the massage mechanism can be designed as an integrated assembly structure.
