Problems solved by technology

[0003] The existing structure of adjusting the seat softness by air has the following disadvantages: the seat softness cannot be automatically selected according to the occupant; inflatable type, the swelling shape of the air bag causes the seat surface to swell, increasing the hardness At the same time, the raised seat surface changes the shape of the seat surface, changes the position of the seat surface occupied by the human body, and reduces the comfort of the seat.

Embodiment 1

[0048] Please refer to figure 1 The structure of a seat softness adjustment device provided for this embodiment, said device includes a control module and at least one soft inflatable bag that can be integrated in the seat, and a pressure sensor 44 for detecting the air pressure in the soft inflatable bag -1. Solenoid valve module 40; the soft inflatable bag 10 is connected to at least one air circuit 11; the control module 60 is provided with a memory; the memory stores the set air pressure corresponding to the soft inflatable bag 10;

[0049] The control module 60 is configured to receive the pressure signal of the pressure sensor 11-1, and adjust the on-off state of the solenoid valve module 40 to give the pressure signal when the pressure signal reaches the set air pressure. The soft inflatable bag 10 is inflated or deflated to adjust the hardness of the seat surface; the soft inflatable bag 10 is also provided with a height-limiting belt structure 30 .

[0050] Among the...

Embodiment 2

[0079] On the basis of the first embodiment, at least one adjustment area is provided in the soft inflatable bag 10; at least two layers of flexible fillers 20 with different hardness are provided in at least one of the adjustment areas. The number of layers of the adjustment area and the flexible filler 20 is optional and not limited to the following combinations:

[0080] 1. If Figure 5 As shown, the number of adjustment areas is two, the first adjustment area 16-1 in the middle and the second adjustment area 16-2 at the edge; the height of the first adjustment area 16-1 and the second adjustment area 16-2 Consistent; wherein the first adjustment area 16-1 is provided with flexible filler A20-1, flexible filler C 20-3 and flexible filler B 20-2 from top to bottom; in the second adjustment area 16-2 from top to bottom The flexible filler A20-1 and the flexible filler B20-2 are provided sequentially from the bottom;

[0081] In this embodiment, a flexible filling C20-3 with...

Embodiment 3

[0093] On the basis of Embodiment 2, the seat softness adjustment device provided by this embodiment, such as Figure 10 As shown, the soft inflatable bag 10 is provided with several air guiding holes 12 for conducting the air 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 flexible fillers for accommodating the cavity filled with air.

[0094] This embodiment provides a seat softness adjustment device, which can be applied to a car seat with ventilation performance, and the wind guided from the bottom of the seat to the seat surface can come out from the air guide hole 12; the seat softness of the present embodiment The design of the air duct of the adjusting device further improves the applicability of the device.

Abstract

The invention discloses a seat hardness adjusting device and an automobile seat. The seat hardness adjusting device comprises a control module and at least one soft inflatable bag capable of being integrated in the seat. The soft inflatable bag is connected with at least one air path. Each air path is provided with an electromagnetic valve module and a corresponding pressure sensor. A memory is arranged in the control module. Set air pressure corresponding to each soft inflatable bag is stored in the storage device. The control module is configured to be used for receiving a pressure signal ofthe pressure sensor and adjusting the on-off state of the electromagnetic valve module to inflate or deflate the soft inflatable bag when judging that the pressure signal reaches the set air pressure, so that the hardness of the surface of the seat is adjusted. The soft inflatable bag is further provided with a height limiting belt structure. The softness and hardness of all parts of the surfaceof the seat can be adjusted by inflating and deflating the soft inflatable bag. Due to the arrangement of the pressure sensor and the control module, the set air pressure can be achieved when the airpressure in the soft inflatable bag is adjusted, and different softness and hardness setting requirements are met.

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 of adjusting the seat softness by air has the following disadvantages: the seat softness cannot be automatically selected according to the occupant; inflatable type, the swelling shape of the air bag causes the seat surface to swell, increasing the hardness At the same time, the convexity of the seat surface changes the shape of the ...
