[0003] Technologies are being developed for vehicles to ensure passenger safety, along with driving performance, convenience, and functionality.

[0004] In particular, among the various safety devices applied to vehicles, airbags are used as the most efficient means to protect occupants from impact.

[0005] These airbags serve as a means to protect occupants during a vehicle collision and consist of a collision sensor that detects a collision, a controller that activates the airbag based on the detection results of the collision sensor, and an airbag module that activates the airbag based on the signal from the controller. Depending on the installation location or the target of protection, they are classified and applied as driver airbags, passenger airbags, side airbags, roof airbags, etc.

[0006] In particular, as autonomous vehicles become more widespread, the seat is configured to change position or rotate 360° to improve passenger convenience.

[0007] However, airbags have limitations in protecting occupants seated in seats that move to various positions from their standard installation location.

[0008] Furthermore, conventional airbags protect only the torso of the occupant and do not consider head protection.

[0009] In addition, there is a problem where the structural restraint capability is reduced because the occupant is restrained using only the tension of the airbag and the external tether.

[0011] The matters described above as background technology are intended only to enhance understanding of the background of the present invention and should not be construed as an acknowledgment that they constitute prior art already known to those skilled in the art. Prior art literature

[0030] Hereinafter, an airbag device for mobility according to a preferred embodiment of the present invention will be examined with reference to the attached drawings.

[0032] FIG. 1 is a drawing showing an airbag device of mobility according to one embodiment of the present invention, FIG. 2 is a drawing showing an airbag device of mobility according to another embodiment of the present invention, FIG. 3 is a drawing showing the operation of the airbag device of mobility shown in FIG. 1, FIG. 4 is a drawing for explaining the deployed airbag cushion of the airbag device of mobility shown in FIG. 1, and FIG. 5 is a drawing for explaining the guide wire and guide part of the present invention.

[0034] As shown in FIGS. 1 to 4, the airbag device of the mobility according to the present invention comprises: a seat (100) consisting of a seat back (110) and a seat cushion (120); a guide wire (200) configured such that one end is connected to the upper side of the seat back (110) and the other end is connected to the side of the seat cushion (120) and has a variable length; and an airbag cushion (300) installed on the upper part of the seat back (110), with a side end slidably connected to the guide wire (200) and configured to unfold toward the front.

[0035] The seat (100) of the present invention is composed of a seat back (110) and a seat cushion (120) and can be configured to be moved or rotated 360° within the interior of the mobility.

[0036] These seats (100) are provided with guide wires (200) and airbag cushions (300).

[0037] Here, one end of the guide wire (200) is connected to the upper side of the seat back (110) and the other end is connected to the side of the seat cushion (120) so as not to interfere with the occupant seated on the seat (100).

[0038] Additionally, the guide wire (200) is configured to have a variable length. That is, the guide wire (200) is configured to have a variable length from the position connected to the seat back (110) to the position connected to the seat cushion (120), and can be configured to be elastically deformable or have a spare length so that the length can be changed.

[0039] In particular, the guide wire (200) is configured such that the maximum extension distance is limited when the length is increased, thereby guiding the deployment of the airbag cushion (300) and simultaneously limiting the deployment position of the airbag cushion (300) to ensure the restraining force of the airbag cushion (300).

[0040] Meanwhile, the airbag cushion (300) is installed on the upper part of the seat back (110), and its side end is slidably connected to the guide wire (200). This airbag cushion (300) can be inflated by receiving gas from an inflator while stored in a housing, and the deployment structure of the airbag cushion (300) is omitted as it is a conventional technique.

[0041] However, the airbag cushion (300) is installed to deploy forward. Here, the forward direction of deployment of the airbag cushion (300) is the front of the occupant seated on the seat (100), and the airbag cushion (300) is inflated to cover the occupant from the front when deployed.

[0042] Through this, the present invention allows the airbag cushion (300) to expand along the guide wire (200) when the airbag cushion (300) is inflated, and the length of the guide wire (200) is stretched by the expansion force of the airbag cushion (300), so that the airbag cushion (300) can expand to cover the passenger in front of the passenger.

[0043] That is, as can be seen in Fig. 3, normally the guide wire (200) is positioned on the side of the seat (100) so as not to interfere with the occupant.

[0044] Here, as can be seen in FIG. 3, when a vehicle collision occurs, the airbag cushion (300) is inflated, and the guide wire (200) is moved forward and its length is extended by the deployment force of the airbag cushion (300). In this way, the airbag cushion (300) is deployed along the guide wire (200), thereby inflating to cover the occupant in front of the occupant, so as to safely restrain and protect the occupant.

[0045] To explain the invention described above in detail, as shown in FIG. 1, a headrest (130) is provided on the upper part of the seat back (110) so as to be positioned higher than the occupant's head and extending to both sides of the occupant's head, an airbag cushion (300) is installed at the upper center of the headrest (130), and a guide wire (200) is connected to the side of the headrest (130).

[0046] Thus, the headrest (130) is formed higher than the occupant's head and extends to both sides of the occupant's head, and the airbag cushion (300) is installed in the center of the headrest (130).

[0047] Thus, the headrest (130) is formed higher than the passenger's head, and as the headrest (130) is positioned higher than the passenger's head, the airbag cushion (300) installed on the headrest (130) does not interfere with the passenger's head when the airbag cushion (300) is deployed.

[0048] Additionally, the headrest (130) is formed to extend to both sides of the occupant's head so as to block the view to both sides of the occupant's head, and restrains the occupant's head in the event of a collision, thereby ensuring the occupant's head stability.

[0049] Accordingly, the guide wire (200) can be installed on the side of the headrest (130) so as not to interfere with the occupant.

[0050] Additionally, the airbag cushion (300) is installed at the upper center of the headrest (130), so that when the airbag cushion (300) deploys, it can be deployed toward the center of the occupant without being unilaterally positioned toward one side relative to the occupant.

[0051] Meanwhile, as shown in FIG. 2, the seat back (110) is formed so that its upper part is higher than the occupant's head and extends to both sides of the occupant's head, and the airbag cushion (300) can be installed in the upper center of the seat back (110).

[0052] Thus, the seat back (110) is formed higher than the occupant's head and extends to both sides of the occupant's head, and the airbag cushion (300) is installed at the upper center of the seat back (110).

[0053] Thus, the seat back (110) is formed higher than the occupant's head, and as the upper part of the seat back (110) is positioned higher than the occupant's head, the airbag cushion (300) installed on the seat back (110) does not interfere with the occupant's head when deployed.

[0054] Additionally, the upper part of the seat back (110) is formed to extend to both sides of the occupant's head so as to block the view to both sides of the occupant's head, thereby restraining the occupant's head in the event of a collision and ensuring the occupant's head stability.

[0055] Accordingly, the guide wire (200) can be installed on the side of the upper part of the seat back (110) so as not to interfere with the occupant.

[0056] Additionally, the airbag cushion (300) is installed at the upper center of the seat back (110), so that when the airbag cushion (300) deploys, it can be deployed toward the center of the occupant without being lopsided toward one side relative to the occupant.

[0057] Meanwhile, as can be seen in FIG. 1, the seat cushion (120) is formed to extend to both sides of the occupant's lower body so as to restrain the occupant's lower body, and a guide wire (200) is connected to the side of the seat cushion (120).

[0058] In this way, the seat cushion (120) is formed so that both sides extend to wrap around the lower body of the occupant, thereby fixing the lower body of the occupant seated on the seat cushion (120) and ensuring stability of the lower body's movement. Additionally, guide wires (200) are connected to both sides of the seat cushion (120), so that the guide wires (200) can move stably forward when the airbag cushion (300) is deployed.

[0059] Meanwhile, the guide wire (200) is composed of a pair, with one end connected to the upper side of the seat back (110) and the other end connected to the front side of the seat cushion (120).

[0060] In this way, the guide wires (200) are configured as a pair and connected to the upper sides of the seat back (110) and the front sides of the seat cushion (120), respectively, so that the two ends of the airbag cushion (300) are connected to the pair of guide wires (200) and can be stably deployed along the guide wires (200).

[0061] Additionally, one end of the guide wire (200) is connected to the upper side of the seat back (110), and the other end is connected to the front side of the seat cushion (120), thereby ensuring a distance that is separated from the front of the occupant when the guide wire (200) is tensioned by the deployment force of the airbag cushion (300).

[0062] As a result, the airbag cushion (300) deployed along the guide wire (200) is deployed away from the front of the occupant, so that the airbag cushion (300) can be deployed safely without colliding with the occupant during the deployment process.

[0063] Meanwhile, the seat cushion (120) is provided with a guide part (121) that is rotatably installed and has a through hole (122) formed therein, and the guide wire (200) passes through the through hole (122) and is connected to the seat cushion (120) via the guide part (121), and the other end that passes through the through hole (122) is provided with a stopper (210) having a diameter larger than that of the through hole (122).

[0064] Additionally, the guide wire (200) is formed to have an initial section (a) from one end connected to the seat back (110) to the guide section (121) and an operating section (b) from the guide section (121) to the other end connected to the seat cushion (120) when the airbag cushion (300) is in an uninflated state.

[0065] That is, as illustrated in FIGS. 1 and 5, a guide portion (121) is rotatably installed in the seat cushion (120), and a through hole (122) through which a guide wire (200) passes is formed in the guide portion (121). As a result, the guide wire (200) is connected to the seat cushion (120) via the guide portion (121).

[0066] Additionally, the guide wire (200) is formed to have an initial section (a) and an operating section (b). That is, the guide wire (200) is divided into an initial section (a) and an operating section (b) centered on the guide part (121) when the airbag cushion (300) is in an uninflated state.

[0067] Here, when the airbag cushion (300) is inflated, the guide wire (200) is moved by the deployment force of the airbag cushion (300), so that the initial section (a) and the operating section (b) are located on one side of the guide section (121). That is, the length of the guide wire (200) from the position connected to the seat back (110) to the position connected to the seat cushion (120) is increased, so that the airbag cushion (300) can be stably deployed along the guide wire (200).

[0068] Additionally, a stopper (210) with a diameter larger than that of the through hole (122) is provided at the other end of the guide wire (200), thereby restricting the other end of the guide wire (200) from detaching from the guide part (121). Accordingly, when the airbag cushion (300) is deployed, the guide wire (200) is tensioned, but the length of tension is limited, thereby ensuring the restraining force of the occupant by the airbag cushion (300).

[0069] Meanwhile, a plurality of connecting rings (310) are provided on the side portion of the airbag cushion (300), and the airbag cushion (300) is connected to the guide wire (200) through the connecting rings (310).

[0070] As a result, when the airbag cushion (300) is deployed, the plurality of connecting rings (310) slide along the guide wire (200), thereby allowing the airbag cushion (300) to be deployed along the guide wire (200).

[0071] Additionally, the airbag cushion (300) is formed to extend along the guide wire (200) when inflated, and multiple dead zones (320) are formed extending horizontally and spaced apart from the side end, extending from the upper side to the lower side.

[0072] Thus, by forming multiple dead zones (320) in the airbag cushion (300), the deployment speed of the airbag cushion (300) is improved, and as the airbag cushion (300) bends at each location where the dead zone (320) is formed, it can not only deploy smoothly along the guide wire (200) but also be deformed into a shape that envelops the occupant.

[0074] The airbag device of the mobility, constructed with the structure described above, has an airbag installed in the seat (100), and the airbag cushion (300) is deployed from the upper side of the seat (100) toward the front of the occupant and inflated to cover the occupant, thereby stably restraining the occupant's upper body.

[0075] Additionally, the airbag cushion (300) is deployed by the guide wire (200) so as to advance forward without interfering with the occupant, and the restraining force of the airbag cushion (300) is secured by the guide wire (200), thereby improving the protection performance of the occupant through the airbag cushion (300).

[0077] Although the present invention has been illustrated and described in relation to specific embodiments, it will be obvious to those skilled in the art that the present invention can be modified and changed in various ways without departing from the technical spirit of the invention as provided by the following claims.
