[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-104118 Summary of the Invention [Problem to be solved by the invention]

[0004] In the configuration described in Patent Document 1, when the base frame is attached to a pair of left and right stays that support the headrest using brackets, the bracket attachment structure must be changed depending on the distance between the left and right stays, which is inconvenient. Therefore, the present invention provides a seat canopy device that can be attached depending on the distance between the pair of left and right stays. [Means for solving the problem]

[0005] To solve the above problems, the seat canopy device of the present invention employs the following means.

[0006] That is, the first invention of the present invention is a seat canopy device having a base frame attached to a pair of left and right stays that support a headrest, and comprising a pair of left and right brackets that are abutted against each of the stays from the front, and a pair of left and right adapters that are connected to each of the brackets so as to sandwich each of the stays between them, and each of the adapters has a first connecting portion that is detachably connected to a base member consisting of the base frame or its connecting fittings by a respective first insertion member that is inserted between them, and a second connecting portion that is detachably connected to each of the brackets by a respective second insertion member that is inserted between them, and at least one of the adapters is capable of connecting the first connecting portion to the base member at the same connecting position regardless of whether it is facing front or back, and is capable of connecting the bracket to the second connecting portion at the same connecting position, and the second connecting portion is offset left and right from the first connecting portion.

[0007] According to the first aspect of the present invention, by reversing the attachment direction of one of the adapters to the base member, the direction in which the second coupling portion shifts relative to the first coupling portion can be reversed left and right. This allows the spacing between the second coupling portions of each adapter to be changed. As a result, the spacing between the second coupling portions of each adapter can be adjusted according to the spacing between the pair of left and right stays.

[0008] A second aspect of the present invention is the seat canopy device according to the first aspect, wherein the other of the adapters has the same configuration as the one of the adapters.

[0009] According to the second aspect of the present invention, the spacing between the second coupling parts of each adapter can be changed in even more various patterns, thereby enabling adjustments such as changing the spacing between the second coupling parts of each adapter in accordance with the spacing between the pair of left and right stays in even more various patterns.

[0010] A third aspect of the present invention is the seat canopy device according to the second aspect, wherein the brackets are common parts and the adapters are also common parts.

[0011] According to the third aspect of the present invention, by standardizing the components of each bracket and each adapter, it is possible to reduce the cost of managing components and prevent incorrect assembly.

[0012] The fourth invention of the present invention is a seat canopy device according to any one of the first to third inventions, wherein each of the first insertion members is a first bolt having a male thread, and the base member is integrally provided with each of the first nuts having a female thread capable of fastening each of the inserted first insertion members.

[0013] According to the fourth aspect of the present invention, the adapters can be connected to the base member simply by fastening the first insertion members to the first nuts that are integral with the base member, thereby simplifying the fastening and removal operations.

[0014] The fifth invention of the present invention is a seat canopy device in which, in any of the first to third inventions above, the first connecting portion of each adapter has clamping pieces that clamp the base member from above and below, and each of the first insertion members is inserted from above and below between the clamping pieces and the base member.

[0015] According to the fifth aspect of the present invention, the first coupling portion of each adapter can be easily and firmly coupled to the base member. Also, by providing a plurality of insertion holes for the first insertion member in the front and rear of the first coupling portion of each adapter and the base member, the coupling position of each adapter relative to the base member can be easily adjusted forward and backward.

[0016] The sixth invention of the present invention is a seat canopy device in which, in any one of the first to third inventions above, each bracket has a contact portion that is contacted with the second connecting portion of each adapter at two positions on the left and right that individually sandwich each stay, and each second insertion member is inserted front and back into the contact portion and the second connecting portion.

[0017] According to the sixth aspect of the present invention, the brackets can be easily and firmly joined to the second joining portions of the adapters so that the stays are sandwiched between them from the front and rear.

[0018] The seventh invention of the present invention is a seat canopy device according to any one of the first to third inventions, wherein each of the second insertion members is a second bolt having a male thread, and each of the adapters is integrally provided with a second nut having a female thread capable of fastening each inserted second insertion member.

[0019] According to the seventh aspect of the present invention, the brackets and the adapters can be connected simply by fastening the second insertion members to the second nuts that are integral with the adapters, thereby simplifying the fastening and removal operations.

[0021] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0022] First Embodiment (Schematic configuration of seat canopy device 1) First, the configuration of a seat canopy device 1 according to a first embodiment of the present invention will be described with reference to Figures 1 to 8. In the following description, when directions such as front, back, up, down, left, and right are indicated, they refer to the directions shown in each figure.

[0023] Furthermore, when a direction, such as the "sheet width direction," is indicated with the word "sheet," it refers to the respective direction based on the sheet S described below. Furthermore, in the following description, when a specific reference drawing is not shown or when there is no reference symbol corresponding to the reference drawing, any of Figures 1 to 8 will be referred to as appropriate.

[0024] As shown in Fig. 1, the seat canopy device 1 according to this embodiment is configured as a canopy device mounted on an automobile seat S. The seat S has a seat back SB that serves as a backrest for a seated person, a seat cushion (not shown) that serves as a seating portion, and a headrest HR that serves as a headrest portion.

[0025] The headrest HR is fixed by inserting a pair of left and right stays HS, which hang down from the bottom of the headrest HR, into the upper part of the seat back SB. The seat canopy device 1 is detachably attached to the exposed part of the pair of left and right stays HS between the headrest HR and the seat back SB.

[0026] Specifically, the seat canopy device 1 has a base frame 2 attached to each stay HS, and a hood 3 attached to the base frame 2. The hood 3 is connected to the base frame 2 so as to be deployable and storable around a rotation axis L extending in the seat width direction.

[0027] The base frame 2 is attached to each stay HS so as to extend in the seat width direction in the rear region of each stay HS. The base frame 2 is formed in a symmetrical shape with extension arms 2A that extend to both sides in the seat width direction from the connection portions with each stay HS and then extend diagonally downward and forward so as to pass outside each side portion of the seat back SB.

[0028] The canopy 3 is rotatably connected to the tip of each extension arm 2A of the base frame 2 via each rotary shaft member 4 which forms a rotation axis L. This connection makes it possible for the canopy 3 to be stored in relation to the base frame 2 by folding the canopy cloth 3C around each rotary shaft member 4 in the area above the headrest HR, or to unfold the canopy cloth 3C by spreading it out forward.

[0029] The hood 3 has a pair of left and right hood frames 3A that form the framework along its peripheral edge, and multiple sub-frames 3B that span in an arch shape between the hood frames 3A. The base end of each hood frame 3A of the hood 3 is connected to the tip end of each extension arm 2A of the base frame 2 by each rotary shaft member 4.

[0030] The hood 3 also has a hood cloth 3C that is placed between each hood frame 3A and supported by each sub-frame 3B in an arched shape. The left and right hood frames 3A are bent in an inverted L shape when viewed from the side. The sub-frames 3B are provided separately from the left and right hood frames 3A in the direction in which they extend.

[0031] Each sub-frame 3B is connected so that its ends, which are connected to the left and right hood frames 3A, can rotate relative to each hood frame 3A around a rotation axis L extending in the seat width direction. The hood cloth 3C has its peripheral edge and inner surface joined to each hood frame 3A and each sub-frame 3B.

[0032] As a result, the canopy 3 is stored so that the canopy cloth 3C is folded above the headrest HR as each of the canopy frames 3A is rotated rearward (clockwise in the figure) about the rotation axis L, and the sub-frames 3B are folded (solid line state in Figure 1). Also, the canopy 3 is stored so that the canopy cloth 3C is folded above the headrest HR as each of the canopy frames 3A is rotated forward (counterclockwise in the figure) about the rotation axis L, and the sub-frames 3B are unfolded (phantom line state in Figure 1).

[0033] As shown in Figure 2, the base frame 2 is integrally attached to a pair of left and right stays HS via a pair of left and right adapters 5 and a pair of left and right brackets 6. The attachment structure of this base frame 2 is configured so that the attachment spacing can be easily adjusted according to the spacing between each stay HS.

[0034] The mounting structure of the base frame 2 to each stay HS will be described in detail below. As shown in Fig. 3, the seat canopy device 1 includes a pair of left and right adapters 5, a pair of left and right brackets 6, and a pair of left and right base members 7 as the mounting structure.

[0035] The pair of left and right adapters 5 are made up of common parts with the same structure. The pair of left and right brackets 6 are also made up of common parts with the same structure. The pair of left and right base members 7 are also made up of common parts with the same structure.

[0036] Each base member 7 is made of a plate bent into a U-shape facing backward in a side view. Each base member 7 has circular first insertion holes 7A formed at two positions on the left and right that penetrate the top and bottom plates. First nuts N1 are welded to two positions on the left and right under the top plate and on the bottom plate of each base member 7 so that screw holes (female threads) are formed at the ends of the corresponding first insertion holes 7A.

[0037] Each base member 7 is set from the front side onto the base frame 2 so that the base frame 2 is sandwiched between the top plate and bottom plate thereof. Each base member 7 is fixed integrally to the base frame 2 by welding the contact portions with the base frame 2. As a result, each base member 7 is provided with its first insertion hole 7A disposed on the front side of the base frame 2.

[0038] Each adapter 5 is also made of a plate bent into a U-shape facing backward in a side view. Each adapter 5 has a first connecting portion 5A that is connected to each of the pair of corresponding left and right base members 7 described above. Each adapter 5 also has a second connecting portion 5B that is connected to each of the pair of corresponding left and right brackets 6 that are assembled so as to abut against each stay HS from the front.

[0039] The top and bottom plates of each adapter 5 are formed as clamping pieces 5C that are set so as to sandwich the corresponding base member 7 from above and below. The first connecting portion 5A described above is formed on each clamping piece 5C. The second connecting portion 5B, that is, the second connecting portion 5B to which the corresponding bracket 6 is attached from the front side and connected, is formed on a front plate 5D that extends to connect the front edges of the clamping pieces 5C.

[0040] The first coupling portion 5A of each adapter 5 has first coupling holes A1 formed in two circular holes at the left and right positions of each clamping piece 5C. As shown in Fig. 4, the hole spacing W1 of these first coupling holes A1 is the same as the hole spacing W1 of the first insertion holes 7A formed in the corresponding base member 7.

[0041] Therefore, by setting each clamping piece 5C of each adapter 5 so as to sandwich it vertically between the corresponding base members 7, it is possible to adjust the position so that all of the first coupling holes A1 are aligned with the positions of the first insertion holes 7A of the corresponding base members 7. After aligning these, each adapter 5 is integrally fixed to the corresponding base member 7 by inserting a first bolt B1 into each first coupling hole A1 from above or below and fastening it with a first nut N1 (see FIG. 5). Here, each first bolt B1 corresponds to the "first insertion member" of the present invention.

[0042] As shown in Fig. 4, the upper and lower clamping pieces 5C of each adapter 5 have chamfered portions 5E that are chamfered diagonally at the inner rear corners of the clamping pieces 5C. In the state shown in the figure, each adapter 5 is fixed to the corresponding base member 7 in a symmetrical orientation with each chamfered portion 5E facing inward, in accordance with the spacing between each stay HS.

[0043] 3, the second coupling portions 5B formed on the front plate 5D of each adapter 5 have second coupling holes B3 formed in circular holes at two positions on the left and right of the second coupling portions 5B. Second nuts N2 are welded to the second coupling portions 5B formed on the front plates 5D at two positions on the left and right of the rear surfaces of the second coupling portions 5B so as to provide screw holes (female threads) behind the corresponding second coupling holes B3.

[0044] 4, the hole spacing W2 of each second coupling hole B3 is set wider than the hole spacing W1 of each first coupling hole A1. Specifically, each first coupling hole A1 and each second coupling hole B3 are configured so that one of them is formed on the side without the chamfered portion 5E (the outer side in the figure) and the other is formed in a position where they are lined up in front of and behind each other, that is, where they are arranged overlapping in the width direction.

[0045] Meanwhile, each of the first and second coupling holes A1 and B3 is configured to be offset such that the other of the holes formed on the side of each chamfered portion 5E (the inner side in the figure) is positioned more inward than the first coupling hole A1. As a result, by inverting each adapter 5 around an axis extending in the front-to-rear direction, as will be described later in Fig. 7, the orientation in which each of the second coupling holes B3 is offset relative to each of the first coupling holes A1 can be changed from the inward orientation shown in Fig. 4 to the outward orientation shown in Fig. 7.

[0046] 3, the pair of left and right brackets 6 have a central portion formed into a hat-shaped plate shape in plan view, with the central portion curved forward relative to the contact portions 6A on both the left and right sides. Each bracket 6 is set so that the recess in its central portion fits into each stay HS from the front, and the contact portions 6A on both the left and right sides are brought into contact with the second connecting portions 5B (front plates 5D) of the corresponding pair of left and right adapters 5 from the front and connected with bolts.

[0047] Second insertion holes A2 that penetrate in a circular shape in the front-to-rear direction are formed in the contact portions 6A on both the left and right sides of each bracket 6. As shown in Fig. 4, the hole spacing W2 of the second insertion holes A2 in each bracket 6 is the same as the hole spacing W2 of the second coupling holes B3 formed in the second coupling portion 5B of each adapter 5.

[0048] Therefore, by setting the abutment portions 6A on both the left and right sides of each bracket 6 so that they abut the second connecting portions 5B (front panels 5D) of the corresponding bracket 6 from the front, it is possible to adjust the positions so that all of the second insertion holes A2 are aligned with the positions of the second connecting holes B3 of the corresponding adapters 5. After aligning these positions, each bracket 6 is fixed integrally to the corresponding adapter 5 by inserting second bolts B2 into the second insertion holes A2 from the front and tightening them with second nuts N2 (see FIG. 5).

[0049] As a result of the above fastening, each bracket 6 and each adapter 5 are fixed integrally with each stay HS so that the stay HS is sandwiched between them. Here, each second bolt B2 corresponds to the "second insertion member" of the present invention. As shown in Figure 3, to release the fastening of each bracket 6 to each adapter 5, it is sufficient to release the fastening of each second bolt B2 inserted into them.

[0050] Similarly, to release the adapters 5 from their respective base members 7, the first bolts B1 inserted into them can be released. In this way, the base frame 2 can be attached and detached as a unit by the simple operation of simply fastening and detaching the first bolts B1 and second bolts B2 to and from the stays HS.

[0051] Specifically, the first nuts N1 and second nuts N2 that are fastened to the first bolts B1 and second bolts B2 are welded to the mating members, so that the fastening and unfastening operations of the first bolts B1 and second bolts B2 can be easily performed without supporting the first nuts N1 and second nuts N2 with the other hand.

[0052] 6 and 7, each of the adapters 5 described above can be inverted around an axis extending in the front-to-rear direction, and still be coupled to the corresponding base member 7 and the corresponding bracket 6. By inverting each adapter 5, it can be switched to a state in which it can be coupled to the brackets 6 at a more outer position than in the state before inversion shown in FIGS.

[0053] Specifically, even when each adapter 5 is turned upside down, it can be integrally coupled to the corresponding base member 7 using each first bolt B1 in a state where it is sandwiched between the upper and lower clamping pieces 5C at the same coupling position as before the inversion. Furthermore, even when each adapter 5 is turned upside down, it can be integrally coupled to the corresponding bracket 6 using each second bolt B2 at the same coupling position as before the inversion.

[0054] By turning each adapter 5 upside down, the second coupling holes B3 are offset from the first coupling holes A1 and face outward, so that each bracket 6 can be coupled to the corresponding second coupling portion 5B of each adapter 5 at a position outside the coupling position before the inversion shown in Figures 3 and 4.

[0055] Therefore, as shown in Figures 6 and 7, even if the spacing between each stay HS is wider than that shown in Figures 3 and 4, each adapter 5 can be attached to each stay HS of the base frame 2 by the simple task of simply turning it over (see Figure 8).

[0056] The orientation of each adapter 5 can be easily confirmed by checking which side the chamfered portion 5E formed at one corner of each adapter 5 faces, so the operation of switching the front and back of each adapter 5 can be easily and reliably performed.

[0057] In this embodiment, the adapters 5 are configured so that the front and back are inverted symmetrically, but the adapters 5 can also be used so that they are asymmetrical. For example, one method is to leave the orientation of one of the left and right adapters 5 shown in Figure 3 as it is and invert the front and back of the other adapter 5. In this way, the spacing between the second coupling portions 5B of each adapter 5 can be changed to a spacing different from the two patterns described above.

[0058] To summarize the above, the seat canopy device 1 according to this embodiment has the following configuration: Note that the reference numerals in parentheses below correspond to the respective components shown in the above embodiment.

[0059] That is, the seat canopy device (1) has a base frame (2) attached to a pair of left and right stays (HS) that support a headrest (HR). The seat canopy device (1) has a pair of left and right brackets (6) that are attached to each stay (HS) from the front, and a pair of left and right adapters (5) that are connected to each bracket (6) so as to sandwich each stay (HS) between them. Each adapter (5) has a first connecting portion (5A) that is detachably connected to the base frame (2) or a base member (7) consisting of its connecting metal fittings by a respective first insertion member (B1) inserted therebetween, and a second connecting portion (5B) that is detachably connected to each bracket (6) by a respective second insertion member (B2) inserted therebetween.

[0060] At least one of the adapters (5) is configured so that the first connecting portion (5A) can be connected to the base member (7) at the same connecting position regardless of whether the adapter is facing upside down or upside down, and the bracket (6) can be connected to the second connecting portion (5B) at the same connecting position, and the second connecting portion (5B) is offset left and right relative to the first connecting portion (5A). According to the above configuration, by reversing the mounting orientation of one adapter (5) to the base member (7), the offset direction of the second connecting portion (5B) relative to the first connecting portion (5A) can be reversed left and right. This allows the spacing between the second connecting portions (5B) of each adapter (5) to be changed. As a result, the spacing between the second connecting portions (5B) of each adapter (5) can be adjusted depending on the spacing between the pair of left and right stays (HS).

[0061] The other of the adapters 5 has the same configuration as the other. With this configuration, the spacing between the second connecting portions 5B of each adapter 5 can be changed in even more various patterns. As a result, the spacing between the second connecting portions 5B of each adapter 5 can be adjusted in even more various patterns according to the spacing between the pair of left and right stays HS.

[0062] Furthermore, the brackets 6 are common parts, and the adapters 5 are also common parts. In this way, by standardizing the parts of the brackets 6 and the adapters 5, it is possible to reduce the cost of managing parts and prevent incorrect assembly.

[0063] Furthermore, each of the first insertion members (B1) is a first bolt (B1) having a male thread. The base member (7) is integrally provided with each of the first nuts (N1) having a female thread that can fasten each of the inserted first insertion members (B1). According to the above configuration, each of the adapters (5) and the base member (7) can be connected simply by fastening each of the first insertion members (B1) to each of the first nuts (N1) that are integral with the base member (7). Therefore, the fastening and removal operations can be easily performed.

[0064] Furthermore, the first coupling portion (5A) of each adapter (5) has clamping pieces (5C) that sandwich the base member (7) from above and below, and each first insertion member (B1) is inserted vertically between the clamping pieces (5C) and the base member (7). According to the above configuration, the first coupling portion (5A) of each adapter (5) can be simply and firmly coupled to the base member (7).

[0065] Furthermore, each bracket (6) has abutment portions (6A) that abut against the second connecting portions (5B) of each adapter (5) at two positions on the left and right that individually sandwich each stay (HS), and each second insertion member (B2) is inserted from the front to the back into the abutment portions (6A) and the second connecting portions (5B). According to the above configuration, each bracket (6) can be simply and firmly connected to the second connecting portions (5B) of each adapter (5) so that each stay (HS) is sandwiched between them from the front to the back.

[0066] Furthermore, each second insertion member (B2) is a second bolt (B2) having a male thread. Each adapter (5) is integrally provided with a second nut (N2) having a female thread that can fasten each inserted second insertion member (B2). With the above configuration, each bracket (6) and each adapter (5) can be connected simply by fastening each second insertion member (B2) to each second nut (N2) that is integral with each adapter (5). Therefore, the fastening and removal operations can be performed easily.

[0067] Other Embodiments Although one embodiment of the present invention has been described above, the present invention can be embodied in various forms other than the above embodiment.

[0068] 1. The seat canopy device of the present invention may be attached to a seat mounted on a vehicle other than an automobile, such as a train, an airplane, or a ship.

[0069] 2. In the above embodiment, each of the pair of left and right adapters is configured so that the first connecting portion can be connected to the base member at the same connecting position even when the adapter is turned over, but it is also possible for only one of the adapters to be configured in this way.

[0070] 3. The base member may be composed of a metal fitting connected to the base frame, or may be composed of the base frame itself. For example, if a first insertion hole is provided through the base frame in the height direction and the first insertion member is inserted by aligning it with the first coupling hole formed in the first coupling portion of each adapter, a configuration can be obtained in which the base frame itself is the base member.

[0071] In this case, the configuration in which the first nut is integrally provided on the base member can be achieved by welding the first nut to the base frame. Also, if the first nut is welded to the front part of the base frame and the first coupling part of the adapter is set so that the first coupling hole aligns with the first nut, then by inserting and fastening the first bolt into these, the adapter can be coupled without forming a first insertion hole in the base frame.

[0072] 4. By arranging multiple first insertion holes formed in the base member and multiple first connecting holes formed in the first connecting portion of each adapter in a line in the front-to-back direction, a configuration can be obtained in which the connecting position of each adapter relative to the base member can be adjusted in the front-to-back direction.

[0073] 5. The pair of left and right adapters or the pair of left and right brackets do not necessarily have to be made up of common parts.

[0074] 6. The first insert member and the second insert member may be clips instead of bolts. [Explanation of symbols]
