Method used

A zero-gravity seat cushion airbag protection device based on occupant protection is designed, which is installed at the bottom of the cushion skeleton, including the cushion airbag and the airbag ejection hole. When the cushion is quickly returned to position, the airbag ejects and supports the cushion foam and skin to support the occupant's legs.

Benefits of technology

Through the airbag protection device, the damage to the occupant's legs caused by rapid diving of the seat cushion is effectively offset, the occupant's restraint and protection are improved, and safety hazards are reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of zero-gravity seats, and in particular to a seat cushion airbag protection device for a zero-gravity seat based on occupant protection. Background Art

[0002] Today's zero-gravity seats are innovative comfort seats. When using zero-gravity seats, passengers can adjust the seats to achieve a large-angle reclining position, which brings a more comfortable sitting position. However, due to the large lifting angle of the seat cushion of the zero-gravity seat, the passengers are in a lying position, and the adjustment range of the seat belt is limited. In an emergency, the restraint force of the seat belt on the body is not enough to fully protect the passengers, which poses a safety hazard. Therefore, the rapid return device for the zero-gravity seat cushion has gradually attracted people's attention. However, the rapid return device of the seat cushion will cause the passenger's legs to fall rapidly, resulting in the displacement of the passenger's center of gravity. Now there is an urgent need for a seat cushion airbag protection device for zero-gravity seats based on passenger protection to optimize the sitting posture to improve the restraint protection of the passengers. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a seat cushion airbag protection device for a zero-gravity seat based on occupant protection, which is used to provide sufficient support for the occupant's thighs and offset the damage to the occupant when the zero-gravity seat cushion dives rapidly, so as to overcome the shortcomings of the above-mentioned prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A seat cushion airbag protection device for a zero-gravity seat based on occupant protection comprises: a seat cushion airbag installation cavity installed at the bottom of a seat cushion frame, a seat cushion airbag located in the seat cushion airbag installation cavity, and an airbag ejection hole opened in the middle of the seat cushion frame. After the seat cushion airbag is ejected, it contacts the seat cushion foam through the airbag ejection hole and props up the seat cushion foam and the seat cushion skin to support the occupant's legs.

[0006] As a preferred embodiment of the present invention, the seat cushion airbag protection device and the seat cushion quick return device are started synchronously.

[0007] The advantages and positive effects of the utility model are:

[0008] 1. The present invention protects the occupants by adding a seat cushion airbag protection device to the zero-gravity seat cushion, which cooperates with the seat cushion quick return device.

[0009] 2. The present invention provides collision protection for the rapid return of the zero-gravity seat cushion by adding a seat cushion airbag protection device. The seat cushion airbag protection device receives the collision signal, and the airbag is detonated to provide support and protection for the occupant's legs, thereby offsetting the energy of the occupant after the collision, and plays a key role in protecting the occupants in a zero-gravity sitting position. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 The utility model is a schematic diagram of the installation structure of the seat cushion airbag protection device and the seat cushion frame.

[0011] Figure 2 It is one of the overall structural schematic diagrams of the seat cushion airbag protection device in the utility model.

[0012] Figure 3 This is the second schematic diagram of the overall structure of the seat cushion airbag protection device in the utility model.

[0013] Figure 4 This is the third overall structural schematic diagram of the seat cushion airbag protection device in the utility model.

[0014] Reference numerals: seat cushion frame 1 , seat cushion airbag mounting cavity 2 , seat cushion airbag 3 , airbag pop-up hole 4 , seat cushion quick return device 5 . DETAILED DESCRIPTION

[0015] In the following description, for the purpose of illustration, in order to provide a comprehensive understanding of one or more embodiments, many specific details are set forth. However, it is apparent that these embodiments may also be implemented without these specific details. In other examples, for ease of describing one or more embodiments, known structures and devices are shown in the form of block diagrams.

[0016] See also Figures 1-4 The present embodiment provides a seat cushion airbag protection device for a zero-gravity seat based on occupant protection, the seat cushion airbag protection device is used to pop out after a car collision (the seat pan frame is impacted by the occupant) to support and protect the occupant's legs. The seat cushion airbag protection device includes: a seat cushion airbag installation cavity 2 installed at the bottom of the seat cushion frame 1, a seat cushion airbag 3 located in the seat cushion airbag installation cavity 2, and an airbag pop-up hole 4 opened in the middle position of the seat cushion frame 1. When the car collides and the seat cushion frame 1 is impacted by the occupant, the seat cushion airbag protection device and the seat cushion collapse mechanism 4 operate synchronously. After the seat cushion airbag 3 is popped out, it contacts the seat cushion foam through the airbag pop-up hole 4 and props up the seat cushion foam and the seat cushion skin to support the occupant's legs, so that the occupant's legs will not fall rapidly and cause injuries when the seat cushion collapses back to its original position.

[0017] Working principle: When the seat cushion quick return device 5 controls the seat cushion frame 1 to dive, the seat cushion airbag protection device is started synchronously, and the seat cushion airbag protection device is used to support the occupant's legs when the seat cushion frame 1 dives, so as to offset the energy of the occupant after the collision. Among them, after the seat cushion airbag protection device receives the collision signal, the seat cushion airbag 3 explodes and pops out from the seat cushion airbag mounting cavity 2. After the seat cushion airbag 3 pops out, it bulges from the airbag pop-up hole 4 and props up the seat cushion foam and skin. The legs in contact with the seat cushion skin are lifted upward with the support of the seat cushion airbag 3, thereby offsetting the damage to the occupant's legs caused by the diving of the seat cushion frame 1.

[0018] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
