Embodiment 1

[0040] Please refer to figure 1 The structure of a seat softness adjustment device provided for this embodiment has a soft inflatable bag 10 that can be integrated in the seat; the soft inflatable bag is connected with an air circuit 11; the soft inflatable bag The inflatable bag 10 is filled with a flexible filler 20; the soft inflatable bag 10 is filled or exhausted through the air path 11 to adjust the hardness of the seat surface;

[0041] The soft air bag 10 is provided with a height limiting structure 30 for limiting the expansion height of the soft air bag 10 when it is inflated.

[0042]Among them, the air path generally refers to the air path structure that provides the air source for the soft inflatable bag. For example, in this embodiment, the air path includes an air nozzle fixed on the soft inflatable bag, and a trachea fixedly connected to the air nozzle; the end of the trachea Connected to the exhaust port of the solenoid valve module 40, the air inlet of the s...

Embodiment 2

[0056] The seat softness adjusting device provided in this embodiment, such as image 3 with Figure 4 As shown, the soft inflatable bag 10 is provided with several air guiding holes 12 for guiding the air flow on both sides of the soft inflatable bag 10 . The air guide tunnel 12 is isolated from the inflation cavity of the soft inflatable bag 10, and the inflatable cavity of the soft inflatable bag 10 is a cavity filled with a flexible filler 20, that is, a cavity for accommodating inflated gas.

[0057] This embodiment provides a seat softness adjustment device, which can be applied to a car seat with ventilation performance. The wind guided from the seat bottom to the seat surface can be blown out from the air guide hole 12, and finally blows through the seat surface to the human body , the design of the air duct of the seat softness adjusting device of this embodiment further improves the applicability of the device.

[0058] This embodiment is also applicable to air suc...

Embodiment 3

[0060] This embodiment provides a car seat 70, the backrest 71, seat cushion 72 and side wings 73 of the car seat 70 are integrated with the seat softness adjusting device in the first embodiment; in other embodiments, also The seat softness adjusting device can be arranged on any one or more positions of the backrest 71 , the seat cushion 72 , and the side wings 73 of the car seat.

[0061] In this embodiment, the gas source of the soft inflatable bag 10 can optionally adopt any of the following methods:

[0062] 1. Provided by a separately set micro air pump;

[0063] 2. Provided by the compressed air in the car body;

[0064] Taking the seat cushion 72 of the car seat 70 as an example, the soft inflatable bag is installed between the seat cover 75 of the seat cushion 72 and the foam structure 74, and the air path of the soft inflatable bag 10 extends through the foam structure 74 from the bottom. Connect to air source.

[0065] In this embodiment, solenoid valve modules ...

Abstract

The invention discloses a seat hardness adjusting device and a car seat. The device is provided with at least one soft air inflation bags capable of being integrated in the seat. The soft air inflation bags are connected with at least one air way. The soft air inflation bags are filled with flexible fillers. The soft air inflation bags are inflated with or discharge air through the air ways so asto adjust the hardness of the surface of the seat. Height limiting structures used for limiting the partial expansion height when the soft air inflation bags are inflated with air are arranged in thesoft air inflation bags. The seat hardness adjusting device is arranged independently, and the supporting performance of the whole seat is not influenced; and through the design of the height limitingstructures, the distance between bag bodies on the upper layers and the lower layers of the soft air inflation bags can be constrained, expectable shape changes happen to the partial shapes of the soft air inflation bags when the soft air inflation bags are inflated with air, when the seat hardness is adjusted, a passenger and the seat still have the large enough contact area, follow-up of the surfaces of the soft air inflation bags and the surface of the seat is achieved better, and attractiveness and comfort of the surface of the seat are further improved.

Description

technical field [0001] The present disclosure generally relates to the technical field of car seats, in particular to a seat softness adjustment device and a car seat. Background technique [0002] In recent years, with people's understanding and improvement of seat comfort, it is found that the traditional view that a comfortable seat has a good ergonomic shape, softness, breathability and support, and gradually realizes the surface of the seat. The degree of softness and hardness can be adjusted intelligently, which has important significance and influence on the application improvement and research of comfort. [0003] The existing structure for adjusting the softness and hardness of the seat through air has the following disadvantages: inflatable type, the shape of the air bag swells to cause the seat surface to swell, while increasing the hardness, the seat surface bulges to change the shape of the seat surface, The position of the seat surface occupied by the human bo...
