Summary of the Invention

Problems to be Solved by the Invention

[0004] When the glove box and the occupant protection device are separate bodies, mounting members for attaching to the vehicle body are provided for each of the glove box and the occupant protection device. However, the mounting members in the case of integrating the glove box and the occupant protection device have not yet been studied.

Means for Solving the Problems

[0005] The present disclosure can be realized in the following forms.

[0006] (1) According to one embodiment of the present disclosure, a glove box integrated occupant protection device is provided for use mounted on a mobile vehicle. The glove box integrated occupant protection device comprises a glove box portion having an inner wall defining an internal space, an occupant protection portion, and a mounting member for attaching the glove box integrated occupant protection device to the mobile vehicle, wherein the glove box portion and the occupant protection portion are adjacent to each other and integrated, and the occupant protection portion comprises an inflatable and deployable airbag body, an inflator supplying gas to the airbag body, and a housing that houses the airbag body and the inflator, and has a shared wall shared with the bottom of the inner wall, wherein the inflator penetrates the housing and is attached to the mounting member. This form of glovebox-integrated occupant protection device includes mounting members for attaching the glovebox-integrated occupant protection device to a mobile body, and the inflator is attached to the mounting members. Therefore, the attachment of the glovebox-integrated occupant protection device and the inflator can be achieved using common components. This reduces the effort required to attach the components compared to a configuration where the components for attaching the glovebox-integrated occupant protection device and the components for attaching the inflator are separate parts. (2) In the glove box integrated occupant protection device of the above form, the housing has a first front wall connected to the front end of the shared wall and extending downward from the shared wall, the mounting member is in contact with the first front wall on the outside of the housing, and the inflator may be attached to the mounting member by penetrating the first front wall. In this form of glove box-integrated occupant protection device, the mounting member contacts the first front wall on the outside of the housing, so compared to a configuration in which the mounting member does not contact the first front wall, the mounting member can support the occupant protection unit more firmly. In addition, the strength of the first front wall through which the inflator passes can be reinforced. Furthermore, since the inflator penetrates the first front wall and is attached to the mounting member, the space inside the glove box can be made wider compared to a configuration in which the inflator is attached to a shared wall. (3) In the glove box integrated occupant protection device of the above form, the inner wall has the shared wall and a second front wall connected to the front end of the shared wall and extending upward from the shared wall, and the mounting member may further contact the second front wall on the outside of the glove box portion. In this form of glove box-integrated occupant protection device, the mounting member is in contact with the second front wall, allowing the mounting member to more firmly support the glove box. (4) In the glove box integrated occupant protection device of the above form, the first front wall is connected to the front end of the shared wall and has a first connecting portion that extends forward and downward, and the inflator may be attached to the mounting member by passing through the first connecting portion. In this form of glovebox-integrated occupant protection device, the inflator is attached to a first connection point that connects to the front end of a shared wall and extends forward and downward, allowing the inflator to be positioned rearward and downward. This allows the airbag body to inflate and deploy more quickly toward the occupant. (5) In the glove box integrated occupant protection device of the above form, the inner wall has the shared wall and a second front wall connected to the front end of the shared wall and extending upward from the shared wall, the second front wall has a second connecting portion connected to the front end of the shared wall and extending forward and upward, and the mounting member may further contact the second connecting portion on the outside of the glove box portion. In this form of glovebox-integrated occupant protection device, the second front wall has a second connecting portion that connects to the front end of the shared wall and extends forward and upward, thus allowing for a wider space within the glovebox compared to configurations in which the second front wall extends only upward or backward and upward. Furthermore, since the mounting member is in contact with the second connection point, the glove box can be supported more firmly compared to a configuration in which the mounting member is not in contact with the second connection point. Additionally, the strength of the second connection point can be reinforced. (6) A glove box integrated occupant protection device of the above form, wherein the housing has a first front wall connected to the front end of the shared wall and extending downward from the shared wall, the inner wall has the shared wall and a second front wall connected to the front end of the shared wall and extending upward from the shared wall, the mounting member has a support portion extending in the vertical direction and an insertion portion extending in the front-rear direction and connected to the support portion, the support portion is in contact with the first front wall on the outside of the housing, the insertion portion penetrates the second front wall and is in contact with the glove box side surface of the shared wall, and the inflator may be attached to the insertion portion by penetrating the shared wall. In this form of glove box-integrated occupant protection device, the support portion is in contact with the first front wall on the outside of the housing, so the occupant protection portion can be supported more firmly compared to a configuration in which the support portion is not in contact with the first front wall. Furthermore, since the insertion portion is in contact with the glove box side of the shared wall, the strength of the shared wall can be reinforced compared to a configuration in which the insertion portion is not in contact with the glove box side of the shared wall. Furthermore, since the inflator is attached to the insertion section by penetrating the shared wall, the occupant protection section can be made more compact in the front-to-back direction compared to a configuration in which the inflator is attached to the first front wall.

[0007] This disclosure can be implemented in various forms. For example, it can be implemented in a vehicle equipped with a glove box-integrated occupant protection device. [Brief explanation of the drawing]

The reinforcement bracket 520 is a plate-shaped member that is attached to the reinforcement body 510 and extends in the vertical direction.

[0010] In this disclosure, the direction along the vehicle's direction of travel is referred to as the "forward-rear direction." The direction perpendicular to the vehicle's occupants, as viewed from their perspective, is referred to as the "up-down direction." The direction along the vehicle's left-right direction (width direction) is referred to as the "left-right direction." The "forward-rear direction," "up-down direction," and "left-right direction" are intersecting directions.

[0011] <Configuration of Crew Protection Unit 200> The occupant protection unit 200 suppresses the impact applied to the occupant when a vehicle collision is detected or predicted. In this embodiment, the occupant protection unit 200 is a knee airbag device that protects the occupant's lower limbs. As shown in Figure 1, the occupant protection unit 200 comprises an airbag body 210, an inflator 220, a housing 230, and a door portion 240.

[0012] The airbag body 210 is a bag that inflates and deploys when gas is introduced. The dashed line in Figure 1 shows the airbag body 210 after inflation and deployment. The airbag body 210 is constructed by sewing together one or more base fabrics. The airbag body 210 is installed inside the housing 230 by inserting the projection 221 of the inflator 220 (described later) into a through hole (not shown). The airbag body 210 is folded compactly by methods such as roll folding and accordion folding.

[0013] The inflator 220 supplies gas to the airbag body 210 when a vehicle collision is detected or predicted. The inflator 220 has a cylindrical external shape. The longitudinal direction of the inflator 220 is aligned with the left-right direction. The inflator 220 is positioned inside the airbag body 210. The inflator 220 has a projection 221. The projection 221 is a male-threaded projection. The projection 221 penetrates the airbag body 210, the first front wall 232 of the housing 230 (described later), and the mounting member 400, and screws into a nut N. In this way, the airbag body 210 and the inflator 220 are fixed to the housing 230.

[0014] The housing 230 houses the airbag body 210 and the inflator 220. The housing 230 has a box-like appearance shape that opens downward. As shown in FIGS. 1 and 2, the housing 230 includes a shared wall 231, a first front wall 232, a rear wall 233, a first left wall 234, and a first right wall 235.

[0015] As shown in FIG. 1, the shared wall 231 is a wall that constitutes the bottom in the housing 230. The shared wall 231 is shared with the bottom of the inner wall 310 of the glove box portion 300 described later. With such a shared structure, the glove box portion 300 and the occupant protection portion 200 can be integrated. The first front wall 232 extends downward from the front end portion of the shared wall 231. A first insertion hole H1 along the front-rear direction is provided in the first front wall 232. The protrusion 221 of the inflator 220 described above is inserted into the first insertion hole H1. The rear wall 233 extends downward from the rear end portion of the shared wall 231.

[0016] As shown in FIG. 2, the first left wall 234 extends downward from the left end portion of the shared wall 231. The first right wall 235 extends downward from the right end portion of the shared wall 231. The first left wall 234 and the first right wall 235 are respectively connected to the first front wall 232 and the rear wall 233.

[0017] As shown in FIG. 1, the door portion 240 covers the opening of the housing 230. A tear line TL is provided in the door portion 240. The tear line TL is a portion where the wall thickness in the door portion 240 is configured to be thinner than other portions. In the present embodiment, the tear line TL is provided along the left-right direction. The door portion 240 splits along the tear line TL when the airbag body 210 expands and deploys.

[0018] <Configuration of the glove box portion 300> The glove box portion 300 is used to store arbitrary articles. As shown in FIG. 1, the glove box portion 300 includes a main body 305 and a lid 320.

[0019] As shown in Figures 1 and 2, the main body 305 has a box-shaped exterior that opens towards the rear. The main body 305 has an inner wall 310. The inner wall 310 defines the internal space of the glove box section 300. The inner wall 310 has a top wall 311, a second front wall 312, a second left wall 313, a second right wall 314, and a shared wall 231. The top wall 311 is the upper wall of the inner wall 310. The second front wall 312 is the front wall of the inner wall 310 and extends downward from the front end of the top wall 311. The second left wall 313 is the left wall of the inner wall 310 and extends downward from the left end of the top wall 311. The second right wall 314 is the right wall of the inner wall 310 and extends downward from the right end of the top wall 311. The shared wall 231 forms the bottom of the inner wall 310 and extends rearward from the lower end of the second front wall 312. As described above, the shared wall 231 is a wall shared with the bottom of the housing 230.

[0020] As shown in Figure 1, the lid 320 covers the opening of the main body 305. The lid 320 is configured to rotate around the hinge 225. This enables the opening to be opened and closed.

[0021] <Configuration of mounting component 400> The mounting member 400 is used to attach the glove box-integrated occupant protection device 100 to the vehicle and to fix the inflator 220 inside the housing 230. The mounting member 400 is made of, for example, a metal such as aluminum or iron, or resin. As shown in Figure 2, the mounting member 400 has an external shape in which multiple plate-shaped members extending in the left-right direction are bent. The mounting member 400 includes a contact portion 410, a first mounting portion 420, and a second mounting portion 430.

[0022] The contact portion 410 supports the occupant protection unit 200 and the glove box unit 300 and is used for mounting the inflator 220. The contact portion 410 has a U-shaped external form when viewed in the vertical direction. As shown in Figures 1 and 2, in this embodiment, the contact portion 410 is in contact with the first front wall 232 on the outside of the housing 230 of the occupant protection unit 200, and is in contact with the second front wall 312 on the outside of the main body 305 of the glove box unit 300. The contact portion 410 is also in contact with the first left wall 234 and the first right wall 235 on the outside of the housing 230 of the occupant protection unit 200. Furthermore, the contact portion 410 is in contact with the second left wall 313 and the second right wall 314 on the outside of the main body 305 of the glove box unit 300. In other words, the contact portion 410 is in contact with the front surface, left surface and right surface of the glove box integrated occupant protection device 100.

[0023] The contact portion 410 is provided with two recesses 411. The recesses 411 are provided with second insertion holes H2 that run in the front-rear direction. The projection 221 of the inflator 220 described above is inserted into the second insertion holes H2. The projection 221 and the nut N are screwed together, fixing the inflator 220 in place within the housing 230.

[0024] Furthermore, a through hole (not shown) is provided at the left and upper ends of the contact portion 410. By inserting a bolt into this through hole, the contact portion 410 is attached to the reinforcement bracket 520.

[0025] The first mounting portion 420 connects to the left end of the contact portion 410. The first mounting portion 420 has a plate-like external shape that extends in the left-right direction. The first mounting portion 420 is provided with a first through hole PH1 that runs in the front-rear direction. The first through hole PH1 is used to insert a bolt or other component when attaching the mounting member 400 to the frame, bracket, etc., of a vehicle.

[0026] The second mounting portion 430 connects to the right end of the contact portion 410, and the second mounting portion 430 has an L-shaped external form when viewed in the vertical direction. The second mounting portion 430 is provided with a second through hole PH2 aligned in the front-rear direction and a third through hole PH3 aligned in the left-right direction. The second through hole PH2 and the third through hole PH3, like the first through hole PH1, are used to insert bolts and other components when attaching the mounting member 400 to the frame, bracket, etc., of a vehicle.

[0027] According to the glove box integrated occupant protection device 100 of the first embodiment described above, the mounting member 400 is used to attach the glove box integrated occupant protection device 100 to the vehicle and to attach the inflator 220 to the housing 230. In other words, the attachment of the glove box integrated occupant protection device 100 and the attachment of the inflator 220 are achieved by common members. This reduces the effort required to attach the glove box integrated occupant protection device 100 compared to a configuration in which the members for attaching the glove box integrated occupant protection device 100 and the members for attaching the inflator 220 are composed of separate parts.

[0028] Furthermore, according to the glove box integrated occupant protection device 100 of the first embodiment, since the contact portion 410 is in contact with the first front wall 232 on the outside of the housing 230, the occupant protection portion 200 can be supported more firmly compared to a configuration in which the contact portion 410 is not in contact with the first front wall 232. In addition, the strength of the first front wall 232 to which the inflator 220 is attached can be reinforced.

[0029] Furthermore, according to the glove box integrated occupant protection device 100 of the first embodiment, the inflator 220 is attached to the mounting member 400 by penetrating the first front wall 232, so that the internal space of the glove box 300 does not become narrower compared to a configuration in which the inflator 220 is attached to the shared wall 231. Specifically, when the inflator 220 is attached to the shared wall 231, the projection 221 of the inflator 220 protrudes into the glove box 300, and the space inside the glove box 300 becomes narrower by the amount of the projection 221. In contrast, the projection 221 of this embodiment protrudes toward the outside of the glove box integrated occupant protection device 100, so that the space inside the glove box 300 does not become narrower.

[0030] Furthermore, in the glove box integrated occupant protection device 100 of the first embodiment, the contact portion 410 is in contact with the second front wall 312 on the outside of the glove box portion 300, so the glove box portion 300 can be supported more firmly compared to a configuration in which the contact portion 410 is not in contact with the second front wall 312.

[0031] Furthermore, according to the glove box integrated occupant protection device 100 of the first embodiment, the contact portion 410 is in contact with the first left wall 234 and the first right wall 235 on the outside of the occupant protection portion 200. Compared to a configuration in which the contact portion 410 is not in contact with the first left wall 234 and the first right wall 235, the occupant protection portion 200 can be supported more firmly in the left-right direction.

[0032] Furthermore, according to the glove box integrated occupant protection device 100 of the first embodiment, the contact portion 410 is in contact with the second left wall 313 and the second right wall 314 on the outside of the glove box portion 300. Compared to a configuration in which the contact portion 410 is not in contact with the second left wall 313 and the second right wall 314, the glove box portion 300 can be supported more firmly in the left-right direction.

[0033] Furthermore, according to the glove box integrated occupant protection device 100 of the first embodiment, a recess 411 is provided in the contact portion 410, and a second insertion hole H2 is provided in the recess 411. Compared to a configuration in which the recess 411 is not provided, the projection 221 of the inflator 220 inserted into the second insertion hole H2 can be prevented from protruding from the contact portion 410. This prevents the projection 221 from interfering with other members. In addition, the provision of the recess 411 prevents workers from mistakenly installing the mounting member 400 with the wrong front or back side.

[0034] Furthermore, according to the glove box integrated occupant protection device 100 of the first embodiment, the mounting member 400 includes a first mounting portion 420 and a second mounting portion 430, so the mounting member 400 can be attached to the vehicle at more locations compared to a configuration in which the mounting member 400 does not include the first mounting portion 420 and the second mounting portion 430. This increases the degree of freedom in the placement of the glove box integrated occupant protection device 100 within the instrument panel 1. In addition, since the glove box integrated occupant protection device 100 can be fixed at more locations, rattling of the glove box integrated occupant protection device 100 attached to the vehicle can be suppressed.

[0035] B. Second Embodiment: Figure 3 is a cross-sectional view of the glove box integrated occupant protection device 100b of the second embodiment. The glove box integrated occupant protection device 100b of the second embodiment differs from the glove box integrated occupant protection device 100 of the first embodiment in the configuration of the first front wall 232, the configuration of the second front wall 312, and the configuration of the contact portion 410. Configurations not described below are the same as those of the glove box integrated occupant protection device 100 of the first embodiment.

[0036] As shown in Figure 3, the first front wall 232 in the glove box integrated occupant protection device 100b of the second embodiment has a first connecting portion 232a and a first extension portion 232b.

[0037] The first connecting portion 232a connects to the front end of the shared wall 231 and extends forward and downward. The inner surface of the first connecting portion 232a has a first surface SF1 and a second surface SF2. The first surface SF1 connects to the inner surface of the shared wall 231 on the housing 230 side and is inclined forward and downward. The second surface SF2 connects to the front end of the first surface SF1 and is inclined forward and downward. The second surface SF2 is inclined closer to the axis in the vertical direction than the first surface SF1. The first connecting portion 232a is provided with a third insertion hole H3. More specifically, the third insertion hole H3 is provided extending forward and upward from the first surface SF1. The projection 221 of the inflator 220 is inserted into the third insertion hole H3. The first connecting portion 232a is thicker than the first extension portion 232b in a cross-section along the front-rear direction.

[0038] The first extension 232b extends forward and downward from the front and lower ends of the first connecting portion 232a. In a cross-section along the front-rear direction, the first extension 232b is thinner than the first connecting portion 232a. The inner surface of the first extension 232b is continuous with the second surface SF2.

[0039] The second front wall 312 has a second connecting portion 312a and a second extension portion 312b.

[0040] The second connecting portion 312a connects to the front end of the shared wall 231, extends upward, and then extends forward and upward. The second connecting portion 312a can also be said to have an inclined L-shape in cross-section along the front-rear direction.

[0041] The second extension 312b extends upward from the front and upper ends of the second connecting portion 312a.

[0042] The contact portion 410 is in contact with the outer surface of the first connecting portion 232a on the outside of the housing 230. The contact portion 410 has a plate-like external shape that extends in the left-right direction. Unlike the contact portion 410 of the first embodiment, the contact portion 410 of the second embodiment does not have a portion that contacts the second front wall 312.

[0043] According to the glove box integrated occupant protection device 100b of the second embodiment described above, the inflator 220 is attached to the first connection portion 232a that extends forward and downward, so the inflator 220 can be positioned further forward compared to a configuration in which the inflator 220 is attached to the first front wall 232 that extends only downward. This allows for a wider interior space. In addition, since the inflator 220 can be positioned at an angle, the direction of the gas ejected from the inflator 220 can be directed backward and downward. This allows the airbag body 210 to inflate and deploy more quickly toward the occupant.

[0044] Furthermore, according to the glove box integrated occupant protection device 100b of the second embodiment, since the second front wall 312 has a second connecting portion 312a that extends forward and upward, the internal space of the glove box portion 300 can be made wider in the forward direction compared to a configuration in which the second front wall 312 does not have a second connecting portion 312a.

[0045] Furthermore, according to the glove box integrated occupant protection device 100b of the second embodiment, the contact portion 410 does not have a portion that contacts the second front wall 312, so the mounting member 400 can be made lighter compared to a configuration in which the contact portion 410 has a portion that contacts the second front wall 312.

[0046] Furthermore, according to the glove box integrated occupant protection device 100b of the second embodiment, the first connecting portion 232a is thicker than the first extension portion 232b in a cross-section along the front-rear direction, thereby increasing the strength of the first connecting portion 232a to which the inflator 220 is attached. Also, since the first extension portion 232b is thinner than the first connecting portion 232a, the glove box integrated occupant protection device 100b can be made lighter compared to a configuration in which the thickness of the first extension portion 232b is greater than or equal to the thickness of the first connecting portion 232a.

[0047] C. Third Embodiment: Figure 4 is a cross-sectional view of the glove box integrated occupant protection device 100c of the third embodiment. The shape of the mounting member 400c of the glove box integrated occupant protection device 100c of the third embodiment differs from that of the glove box integrated occupant protection device 100b of the second embodiment. Configurations not described below are the same as those of the glove box integrated occupant protection device 100b of the second embodiment.

[0048] As shown in Figure 4, the mounting member 400c has a crank shape in a cross-section along the front-rear direction. The mounting member 400c has a first contact portion 410a, a second contact portion 410b, and a cover portion 415.

[0049] The first contact portion 410a is in contact with the first connecting portion 232a on the outside of the housing 230. The first contact portion 410a has a plate-like external shape that extends in the left-right direction.

[0050] The second contact portion 410b is connected to the rear and upper end of the first contact portion 410a and extends forward and upward. The second contact portion 410b has a plate-like external shape that extends in the left-right direction. The second contact portion 410b is in contact with the second connecting portion 312a on the outside of the glove box portion 300.

[0051] The cover portion 415 is connected to the front and lower ends of the first contact portion 410a and extends downward. The cover portion 415 has a plate-like external shape that extends in the left-right direction.

[0052] According to the glove box integrated occupant protection device 100c of the third embodiment described above, the mounting member 400c has a first contact portion 410a and a second contact portion 410b, so it can support both the outside of the occupant protection portion 200 and the outside of the glove box portion 300. This makes it possible to suppress rattling of the glove box integrated occupant protection device 100c when a large impact occurs when the inflator 220 is operated.

[0053] Furthermore, according to the glove box integrated occupant protection device 100c of the third embodiment, the mounting member 400c is equipped with a cover portion 415, which increases the strength of the mounting member 400c compared to a configuration in which the mounting member 400c is not equipped with a cover portion 415. In addition, when a worker installs the mounting member 400c, by installing it so that the cover portion 415 is positioned downwards, it is possible to prevent the mounting member 400c from being installed in the wrong orientation.

[0054] D. Fourth Embodiment: Figure 5 is a cross-sectional view of the glove box integrated occupant protection device 100d of the fourth embodiment. The glove box integrated occupant protection device 100d of the fourth embodiment differs from the glove box integrated occupant protection device 100 of the first embodiment in the position where the inflator 220 is attached, the shape of the second front wall 312d, and the shape of the mounting member 400d. Configurations not described below are the same as those of the glove box integrated occupant protection device 100 of the first embodiment.

[0055] As shown in Figure 5, the inflator 220 is mounted through the shared wall 231. The shared wall 231 is provided with a fourth insertion hole H4 that is oriented vertically for inserting the projection 221 of the inflator 220.

[0056] The glove box section 300 is equipped with a cap 330. The cap 330 is a component for concealing the protrusion 221 of the inflator 220. The cap 330 has an L-shape in cross-section along the front-rear direction. The cap 330 is connected to the second front wall 312d and the shared wall 231.

[0057] The second front wall 312d is provided with a fourth through-hole PH4 in its lower part, which is oriented in the front-rear direction. The insertion portion 450 of the mounting member 400d, which will be described later, is inserted into the fourth through-hole PH4.

[0058] The mounting member 400d has a support portion 440 and an insertion portion 450. The mounting member 400d has an L-shape in cross-section along the front-rear direction.

[0059] The support portion 440 extends in the vertical direction. The support portion 440 is in contact with the first front wall 232 on the outside of the housing 230.

[0060] The insertion portion 450 connects to the upper end of the support portion 440 and extends in the front-rear direction. The insertion portion 450 is in contact with the inner surface of the shared wall 231 on the glove box portion 300 side. The insertion portion 450 is provided with a fifth insertion hole H5 that runs in the vertical direction. The projection 221 of the inflator 220 is inserted into the fifth insertion hole H5.

[0061] According to the glove box integrated occupant protection device 100d of the fourth embodiment described above, since the inflator 220 is mounted through the shared wall 231, the occupant protection unit 200 can be made more compact in the front-rear and left-right directions compared to a configuration in which the inflator 220 is mounted on another wall of the housing 230.

[0062] Furthermore, according to the glove box integrated occupant protection device 100d of the fourth embodiment, the insertion portion 450 is in contact with the inner surface of the shared wall 231 on the glove box portion 300 side, thus reinforcing the strength of the shared wall 231. This makes it possible to suppress damage to the shared wall 231 caused by the impact generated when the inflator 220 is operated.

[0063] Furthermore, according to the glove box integrated occupant protection device 100d of the fourth embodiment, the glove box portion 300 is equipped with a cap 330, so compared to a configuration without a cap 330, the reduction in aesthetic appeal due to the protrusion 221 of the inflator 220 can be suppressed.

[0064] E. Other embodiments: (E1) In the first embodiment described above, the contact portion 410 does not have to be in contact with the first front wall 232 on the outside of the housing 230, nor does it have to be in contact with the second front wall 312 on the outside of the glove box portion 300. That is, the mounting member 400 may have a configuration such that the contact portion 410 is spaced apart from the first front wall 232 and the second front wall 312. In this configuration as well, the member for attaching the inflator 220 to the housing 230 and the member for attaching the glove box integrated occupant protection device 100 to the vehicle can be made common by the mounting member 400.

[0065] (E2) In the first embodiment described above, the contact portion 410 may be configured to contact only the first front wall 232 and not the second front wall 312. In this configuration, the mounting member 400 can support the occupant protection portion 200. Alternatively, the contact portion 410 may be configured to contact only the second front wall 312 and not the first front wall 232. In this configuration, the mounting member 400 can support the glove box portion 300.

[0066] (E3) In the first embodiment described above, the contact portion 410 was in contact with the first left wall 234 and the first right wall 235 of the housing 230 and the second left wall 313 and the second right wall 314 of the glove box portion 300, but the disclosure is not limited thereto. The contact portion 410 does not have to be in contact with the first left wall 234 and the first right wall 235 and the second left wall 313 and the second right wall 314. The contact portion 410 may also be in contact with a part of the first left wall 234, the first right wall 235, the second left wall 313, and the second right wall 314.

[0067] (E4) In each of the above embodiments, the glovebox-integrated occupant protection devices 100, 100b, 100c, and 100d may be installed on any moving body other than a vehicle. Such moving bodies include, for example, ships, airplanes, spacecraft, and so-called flying cars. Furthermore, the moving body does not necessarily have to be a device that realizes actual movement, but may be a device that realizes virtual movement, such as a simulator.

[0068] This disclosure is not limited to the embodiments described above, and can be implemented in various configurations without departing from its spirit. For example, the technical features in the embodiments corresponding to the technical features in each form described in the summary of the invention can be replaced or combined as appropriate in order to solve some or all of the above-described problems, or to achieve some or all of the above-described effects. Furthermore, if a technical feature is not described as essential in this specification, it can be deleted as appropriate. [Explanation of Symbols]
