Specific embodiments

[0026] The present utility model will be further described below in conjunction with the specification and embodiments, which can enable those skilled in the art to understand the present utility model more comprehensively, but does not limit the present utility model in any way.

[0027] Embodiment 1

[0028] To solve the technical problems existing in the background art, this embodiment discloses a double-chamber central airbag, as Figures 1 to 2 shown, including: an airbag 1, the airbag 1 at least includes: a first airbag 6, and a second airbag 5 connected to the first airbag 6; at least one through hole 9 is provided inside the first airbag 6 and the second airbag 5; a generator 2 is disposed in the first airbag 6; a fixing mechanism is installed on the right side of the main driver's seat sheet metal and connected to the first airbag 6 and the generator 2; lugs 8 are disposed around the outer side of the bottom of the first airbag 6 to form a closed annular structure, and the fixing mechanism is disposed in the closed annular structure. The airbag is installed on the right side of the main driver's seat of the vehicle. When a collision accident occurs, the airbag 1 expands and unfolds from the seat to protect the occupant. During the unfolding process, there should be no flying objects flying out and no structure blocking the unfolding of the airbag. This requires the center console to be as simple as possible and there should be no complex structure on the surface. An airbag 1 having a first airbag 6 and a second airbag 5 is provided. When a side collision occurs, the airbag 1 unfolds between the main driver and the co-driver. The first airbag 6 unfolds first and can quickly provide support for the chest, abdomen and buttocks of the main driver. The second airbag 5 then unfolds to support the head of the main driver, reducing the displacement of the main driver during the collision and the secondary injury caused by the collision between the main driver and the co-driver. Through a reasonable unfolding sequence, the distal airbag can more effectively protect various parts of the occupant and improve the overall protection effect.

[0029] In a further embodiment, the first airbag 6 has a predetermined height, the second airbag 5 has a predetermined width, the second airbag 5 is disposed above the first airbag 6, and one side of the first airbag 6 has a connecting portion 10. The main unfolding directions of the airbag are in the forward and upward directions. The predetermined height of the first airbag 6 ensures the protection of the buttocks, chest and abdomen, and the predetermined width of the second airbag 5 ensures the protection of the head.

[0030] In a further embodiment, the fixing mechanism includes: a bracket 4 connected to the generator 2, a first clamp 3 disposed on one side of the bracket 4 and connected to the connecting portion 10, a second clamp 11 disposed on one side of the first clamp 3 and connected to the lug 8, and at least one third clamp 12 disposed on the other side of the bracket 4. The bracket 4, the third clamp 12, and the generator 2 are fixed inside the seat by nuts. The fixing mechanism ensures the reliable deployment of the airbag during a collision and improves the stability of the system. The lug 8 serves to fix the position of the airbag and prevent the airbag from shifting during deployment.

[0031] In a further embodiment, a pull strap 7 is provided between the first airbag 6 and the second airbag 5. The pull strap 7 controls the deployment direction and speed of the airbag and improves the stability of the airbag during deployment. The entire central airbag is in a three-dimensional state in its natural state.

[0032] Embodiment II

[0033] Step 1: Arrange the airbag bag 1. Lift the entire airbag bag 1 to smooth the bags, so that the first airbag 6 and the second airbag 5 are laid flat on the table.

[0034] Step 2: Start folding the second airbag 5 downwards.

[0035] Step 3: Stop folding when reaching the dotted line position (close to the upper boundary line of the two airbag patterns).

[0036] Step 4: Fold the lower half of the second airbag 5 upwards along the dotted line position (close to the upper boundary line of the two airbag patterns) and pre-sew it to the first airbag 6.

[0037] Step 5: Flip the lower half of the first airbag 6 upwards along the dotted line (flush with the edge of the lug 8).

[0038] Step 6: Flip the upper half of the first airbag 6 downwards along the dotted line.

[0039] Step 8: Fold the entire airbag bag 1 along the dotted line and in the direction of the arrow.

[0040] Step 9: The figure shows a schematic diagram of the folded finished product.

[0041] As Figures 3 to 11 shown, the two chambers of the first airbag 6 and the second airbag 5 are connected by unequal circles. The connection part simulates the pull strap 7 to control the inflation rate. The above folding method enables the airbag bag 1 to deploy the first airbag 6 first and then the second airbag 5 after deployment. When not in operation, the folded airbag bag 1, the bracket 4, and the generator 2 are fixed inside the seat by nuts.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
