Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
As shown in fig. 1, a ceiling airbag 100 according to an embodiment of the present invention is installed in a ceiling of a vehicle. Fig. 2 is a schematic view of the main components of a ceiling airbag according to an embodiment of the present invention, and as shown in fig. 2, a ceiling airbag 100 according to an embodiment of the present invention includes: a main bag 10, a sub-bag 20, and an inflation apparatus; the auxiliary air bags 20 are arranged on the left side and/or the right side of the main air bag 10 and are connected with the main air bag 10 but do not penetrate through the main air bag; the inflating apparatus is used to inflate the primary airbag 10 and the secondary airbag 20.
In the embodiment shown in fig. 1 to 8, the ceiling airbag 100 is installed in the ceiling above the rider, and the secondary bag is disposed on the left side of the primary bag, and the secondary bag is deployed to be located between the rider and the rider. The left side is the left-hand direction of the occupant when facing the direction of travel of the vehicle. The safety of passengers at the auxiliary driving position under most collision working conditions can be protected by adopting the main air bag, the auxiliary air bag which is connected with the main air bag but is not communicated with the main air bag is arranged on the left side of the main air bag, so that mutual injury caused by collision between the passengers at the main driving position and the auxiliary driving position under the condition of offset collision or seat rotation collision can be avoided, and the safety of the automobile is improved. It should be noted that in the embodiment shown in fig. 1-8, a secondary air bag may also be provided to the right of the primary air bag to avoid injury due to a collision between the occupant in the rider position and the vehicle body in the event of an offset collision or a seat swivel collision.
Although in the embodiment shown in fig. 1 to 8, the ceiling airbag 100 is installed in the ceiling above the rider, the secondary bag is provided on the right side of the primary bag. It will be appreciated by those skilled in the art that the ceiling airbag 100 may also be installed in a ceiling above a main cab during actual use. The safety of passengers at the main driving position under most collision working conditions can be protected by adopting the main air bag, the auxiliary air bag which is connected with the main air bag but is not communicated with the main air bag is arranged on the right side of the main air bag, so that mutual injury caused by collision between the passengers at the main driving position and the auxiliary driving position under the conditions of offset collision or seat rotation collision can be avoided, and the safety of the automobile is improved. It should be noted that the auxiliary bag may be provided on the left side of the main bag to avoid injury due to collision between the driver and the vehicle body in the event of offset collision or seat rotation collision.
In an alternative embodiment shown in fig. 2, 3, 5, 7, the inflator device includes a first generator 30 and a second generator 40; the first generator 30 is used to inflate the primary airbag 10 and the second generator 40 is used to inflate the secondary airbag 20. The two independent gas generators are arranged, the expansion time of the main air bag and the auxiliary air bag can be controlled by adjusting the ignition time of the generators, the internal pressure of the bag after the main air bag and the auxiliary air bag are completely expanded can be conveniently controlled respectively, and the safety guarantee effect of the air bags on passengers is improved.
Optionally, the ignition timing of the first generator is earlier than the ignition timing of the second generator when the roof airbag is in operation. The air bag starts to be inflated when the generator is ignited, and ignition time of the first generator and the second generator can be set by adjusting a program of the controller in the practical application process. As shown in fig. 5 and 6, when the ceiling airbag is operated, the first generator 30 inflates the main bag 10, and the sub-bag 20 is carried out while the main bag 10 is being deployed. Then, the second generator 40 inflates the secondary air bag 20, and the secondary air bag 20 is gradually deployed. In an alternative embodiment shown in FIG. 6, the first generator 30 continues to inflate the primary airbag 10 during inflation of the secondary airbag 20 by the second generator 40. In practice, the inflation of the main bag 10 may be completed before the inflation of the auxiliary bag 20 is performed. Compared with the mode that the inflation process of the main air bag 10 is completed before the inflation work of the auxiliary air bag 20 is performed, the auxiliary air bag 20 is inflated before the inflation of the main air bag 10 is completed, the auxiliary air bag 20 can be unfolded as soon as possible, and the collision injury between two passengers caused by the fact that the auxiliary air bag 20 is not unfolded in time is avoided. The time interval between the ignition time of the first generator and the ignition time of the second generator can be selectively set according to actual conditions.
The connection manner between the main bag 10 and the sub-bag 20 can be selectively set according to the actual situation. Alternatively, the primary bag 10 and the secondary bag 20 are connected by: sewing or sticking. As shown in fig. 3-5 and 7, the main bag 10 and the auxiliary bag 20 are connected by sewing, and 50 is a sewing line. Of course, two connecting modes of sewing and pasting can be adopted at the same time.
Alternatively, the primary bag 10 is a three-dimensional bag and the secondary bag 20 is an elongated bag. The three-dimensional type is a three-dimensional configuration with a little difference in length (the size of the automobile in the advancing direction) and width (the size of the passenger in the left-right direction) and height (the size of the passenger in the direction perpendicular to the road surface where the automobile is located) in space, and the strip-shaped type is a three-dimensional configuration with at least one size parameter in the length, the width and the height in the space being obviously larger or smaller than other size parameters. As shown in fig. 3 and 4, the main bag 10 has substantially the same length and height, and the auxiliary bag 20 has a height and length substantially greater than the width. By making the main bag 10 a three-dimensional bag, the wrapping and cushioning effect on the occupant after the main bag is deployed can be improved, and the occupant safety can be improved. By making the sub-bag 20 a long bag, the effect of protecting the passenger or the vehicle body from the passenger after the sub-bag is deployed can be improved, and the safety of the passenger can be improved.
Alternatively, when the ceiling airbag is operated, the internal pressure of the bag when the main bag and the sub bag are in contact with the occupant is a predetermined pressure threshold value. The inflation quantity of the main air bag and the auxiliary air bag can be accurately controlled under the collision working condition by presetting the pressure threshold values of the main air bag and the auxiliary air bag. The value of the pressure threshold can be selectively set according to actual conditions, for example, set to 20 kPa.
According to the technical scheme of the invention, the main air bag is adopted to protect the safety of passengers at the corresponding position of the main air bag under most collision working conditions; the auxiliary air bag which is connected with the main air bag but is not communicated with the main air bag is adopted, so that mutual injury caused by collision between two passengers under the condition of offset collision or seat rotation collision can be avoided, and the safety of the automobile is improved.
The above-described embodiments should not be construed as limiting the scope of the invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions can occur, depending on design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
