Problems solved by technology

However, due to its almost fully enclosed structure, if you want to directly arrange ventilation, because there is not enough air intake, and the fan cannot be directly fixed on the plate frame, so in the domestic and German markets, there is no realization based on the plate frame. Ventilation function for the second row of seats

Embodiment 1

[0057] like figure 1 As shown, the present embodiment provides a car seat, the seat back includes sequentially from front to back in the thickness direction: a face cover 370, a foam body 310, an inner 3D-mesh 320, a gasket 330 and a backrest frame 350;

[0058] A sealed cavity is enclosed between the foam body 310 and the gasket 330, and the inner 3D-mesh 320 is filled in the sealed cavity to maintain the air in the sealed cavity (even when the seat is seated and the backrest is squeezed). The air outlet 311 is arranged on the front side (passenger side) of the foam body 310 to communicate with the inside and outside of the sealed chamber; the face cover 370 covers the foam body 310 In addition, an air passage hole is provided at a corresponding position of the air outlet hole 311 . The sealing gasket 330 is provided with a via hole 331 , and a fan 360 is provided at the via hole 331 for blowing air into the sealed cavity and then blowing out through the air outlet hole 311 ...

Embodiment 2

[0071] This embodiment is basically the same as Embodiment 1, except that the car seat in this embodiment also includes a headrest. like Image 6 As shown, the headrest includes: a base module 10 (body), and a wing portion 20 arranged on the base module 10, and a speaker 30 is arranged on the wing portion 20; the wing portion 20 is divided into a left wing portion 21 and a right wing portion 20. The wings 22; the left wing 21 and the right wing 22 are respectively provided with a speaker 30. On a projection plane perpendicular to the front-rear direction of the vehicle body, the left wing portion 21 and the right wing portion 22 are respectively arranged on the left and right sides of the driver's or passenger's head. In the present application, the front side of the headrest is the side on which the passenger or driver sits, and the left and right hands of the passenger or driver correspond to the left and right sides of the headrest, respectively.

[0072] In this applicat...

Embodiment 3

[0087] This embodiment is basically the same as Embodiment 1, except that:

[0088] like Figure 14 As shown, an audio headrest for a car seat disclosed in this embodiment is provided with an execution module 100 for maintaining and changing the swing angle of the wings.

[0089] The execution module 100 in this embodiment is arranged on the base module 10 ; or, there is an installation space on the base module 10 , and the execution module 100 is arranged on the middle fixing plate 50 .

[0090] The execution module 100 includes: a cylindrical body 110 , a first push rod 120 , a second push rod 130 and a rack and pinion transmission pair 140 . The cylindrical body 110 is generally disposed along the front and rear directions of the vehicle body. The top ends of the first push rod 120 and the second push rod 130 are inserted into the cylindrical body 110 from the front and rear ends respectively. The middle through hole of the body 110 slides.

[0091] The rack-and-pinion t...

Abstract

The invention provides an automobile seat. A seat backrest of the automobile seat sequentially comprises a foaming body, an inner 3D-mesh, a sealing gasket and a backrest framework from front to back in the thickness direction. A sealing containing cavity is defined between the foaming body and the sealing gasket, and the sealing containing cavity is filled with the inner 3D-mesh and used for keeping an air duct in the sealing containing cavity unblocked. Air outlet holes communicated with the inside and the outside of the sealed accommodating cavity are formed in the front side surface of the foaming body; a through hole is formed in the sealing gasket, and a fan is arranged at the through hole and used for blowing air into the sealing containing cavity and then blowing the air out through the air outlet hole. On the premise of not changing a vehicle body structure and a framework, the ventilation structure of the seat is designed, through ingenious arrangement of the positions of the fan and the air outlet in foaming and application of sealing gasket materials such as 3D-mesh and felt, directions of the air inlet and the air outlet in necessary ventilation elements and the airflow direction are planned, structural limitation of a plate type framework and the like is broken through, and the ventilation function of the seat is realized.

Description

technical field [0001] The present invention relates to the technical field of automobile seats, in particular to an automobile seat with ventilation function. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the riding experience of cars. As the user's direct carrying equipment in the car, the function and comfort of the seat directly affect the driving experience. At present, in the mid-size sedans on the market, the interior functions of the car are mainly concentrated on the main and passenger seats in the front row, such as memory, ventilation, heating, massage functions, etc., while the second row seats are slightly single in terms of functions. The function is also only used on the rear seats of the highest configuration, and the ventilation function is not present. The front seat has relatively few functional design constraints due to its independent frame and wide operating space, while the seco...
