[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-75727 Summary of the Invention [Problem to be solved by the invention]

[0004] In the partition device described in the aforementioned Patent Document 1, a plate-shaped panel is fixed to a headrest via a fastener. Specifically, as shown in FIG. 7, the partition device 100 includes a curved panel 101 made of transparent resin, a reinforcing member 102 that reinforces the panel 101, an attachment member 103 attached to the reinforcing member 102, and an air blower 104. The panel 101 is disposed so as to cover a headrest 106 attached to a seat back 105 from the rear and left side. The reinforcing member 102 is a metal member that is substantially L-shaped when viewed from above and is attached to the lower part of the panel 101 on the headrest 106 side, extending horizontally. The attachment member 103 is attached to the rear part of the reinforcing member 102 on the headrest 106 side and fixed to a pair of left and right stays of the headrest 106. The air blower 104 is attached to the headrest 106 side of the panel 101 and draws air from the right side and blows it toward the left front of the head of a seated occupant P. Here, since the metal reinforcing member 102 is attached to the bottom of the panel 101, the panel 101 can be sufficiently reinforced, but there is a problem in that the weight of the partition device 100 increases due to the presence of the reinforcing member 102.

[0005] In view of such demands, an object of the present invention is to provide a partition device that can ensure sufficient strength and rigidity of the panels without using separate reinforcing members or the like. [Means for solving the problem]

[0006] The first invention of the present invention is a partition device having a panel that covers a headrest attached to the upper part of a seat back from the rear and the side, the panel having a rear panel portion that covers the headrest from the rear and a side panel portion that covers the headrest from the side, the panel is attached to a pair of left and right stays of the headrest via brackets attached to the lower part of the side surface of the headrest in the rear panel portion, and a lower bead is formed at the lower part of the side panel portion extending from the bracket in an approximately horizontal direction from a position that overlaps or is spaced apart from the mounting portion of the bracket.

[0007] According to the first aspect of the present invention, the lower bead is formed at the bottom of the side panel, extending from the bracket in a substantially horizontal direction from a position overlapping or spaced apart from the bracket mounting portion, ensuring sufficient strength and rigidity of the panel without the need for additional components such as reinforcing members, thereby enabling the weight of the partition device to be reduced.

[0008] A second aspect of the present invention is characterized in that, in the first aspect, the panel is made of a transparent resin.

[0009] According to the second aspect of the present invention, the partition device does not have any separate members such as reinforcing members attached to the lower parts of the side panel portions of the panels, so that the transparency of the panels makes it possible to prevent obstruction of lateral visibility.

[0010] The third invention of the present invention is characterized in that, in the first or second invention, the side panel portion of the panel has at least one additional bead with an approximately U-shaped cross section formed above the lower bead and extending approximately parallel to the lower bead.

[0011] According to the third aspect of the present invention, at least one additional bead is formed in addition to the lower bead in the side panel portion of the panel, so that the strength and rigidity of the panel can be more sufficiently ensured.

[0012] A fourth aspect of the present invention is characterized in that, in the first or second aspect of the invention, the bracket has a main body formed by bending a metal plate material at a plurality of parallel bending lines, and a stay pressing member that is fastened and fixed to the main body while sandwiching the pair of left and right stays.

[0013] According to the fourth aspect of the present invention, the bracket can have a simple structure.

[0014] The fifth invention of the present invention is characterized in that, in the above-mentioned fourth invention, the main body portion is bilaterally symmetrical, has one central portion and a pair of left and right side portions sandwiching the central portion, and by changing the central portion, it can be attached to multiple pairs of left and right stays with different spacing.

[0015] According to the fifth aspect of the present invention, by changing only the central portion of the main body, it is possible to attach it to a plurality of pairs of left and right stays with different intervals, thereby reducing the size of replacement parts and reducing the cost of the bracket.

[0017] A partition device 10 according to one embodiment of the present invention will be described with reference to Figures 1 to 6. In the following description, directions will be described based on the up, down, front, back, left, and right directions shown in each figure. Here, the up, down, front, back, left, and right directions are defined based on the automobile seat 1 when the automobile seat 1 to which the partition device 10 is attached is installed in the automobile.

[0018] As shown in FIG. 1, the automobile seat 1 has a seat cushion (not shown) that supports the buttocks and thighs of the seated occupant P, a seat back 2 that supports the waist and back of the seated occupant P, and a headrest 3 that supports the head of the seated occupant P.

[0019] As shown in Figures 1 and 5, the partition device 10 has a panel 20 that covers the headrest 3 from the rear and left side, a first bracket 30 for attaching the panel 20 to a pair of left and right stays 3a of the headrest 3, and a blower device 40.

[0020] As shown in FIGS. 1 to 4 , the panel 20 is a curved member formed by vacuum-forming a transparent polycarbonate resin or acrylic resin plate material, and includes a rear panel portion 21 that covers the headrest 3 from behind, and a side panel portion 22 that covers the headrest 3 from the left side. The rear panel portion 21 and the side panel portion 22 are smoothly connected. A lower bead 23 is formed at the bottom of the side panel portion 22, starting from the left end of the rear panel portion 21 and extending forward in a substantially horizontal direction to near the front end of the side panel portion 22. The lower bead 23 has a substantially U-shaped cross section that opens to the right. An upper bead 24 is formed at the top of the side panel portion 22, starting from the left end of the rear panel portion 21 and extending forward in a substantially horizontal direction to near the front end of the side panel portion 22. The upper bead 24 has a substantially U-shaped cross section that opens to the right. The rear end of the lower bead 23 and the rear end of the upper bead 24 are located at approximately the same position in the left-right direction, and the front end of the lower bead 23 is located slightly forward of the front end of the upper bead 24 in the front-rear direction. A middle bead 25 is formed between the lower bead 23 and the upper bead 24 at the rear end side of the side panel portion 22, extending approximately horizontally to the rear panel portion 21. The middle bead 25 has a generally arc-shaped cross section that opens toward the right. A case 41 of the air blower 40, described below, is attached to the inner surface of the middle bead 25, which is the surface facing the headrest 3. The lower bead 23, the upper bead 24, and the middle bead 25 all contribute to increasing the strength and rigidity of the panel 20. Here, the upper bead 24 and the middle bead 25 each correspond to an "additional bead" in the claims.

[0021] 1 and 5, first bracket 30 is a member formed by bending a metal plate. First bracket 30 is formed by connecting a left side member 31, a right side member 32, a central member 33, and two stay retaining members 34 with four screws 35. Left side member 31, right side member 32, and central member 33 form a body portion 38 that is bilaterally symmetrical.

[0022] The left-side component 31 includes a base plate 31a, a vertical plate 31b extending forward from a bending line 31f at the left end of the base plate 31a, and a horizontal plate 31c extending rightward from the bending line 31f at the front end of the vertical plate 31b in parallel with the base plate 31a. Two elongated holes 31d extending parallel to each other in the left-right direction are formed in the base plate 31a. Two screw holes 31e aligned in the left-right direction are formed in the horizontal plate 31c. The right-side component 32 is formed in a symmetrical shape to the left-side component 31. That is, the right-side component 32 includes a base plate 32a, a vertical plate 32b extending forward from a bending line 32f at the right end of the base plate 32a, and a horizontal plate 32c extending leftward from the bending line 32f at the front end of the vertical plate 32b in parallel with the base plate 32a. Two elongated holes 32d extending parallel to each other in the left-right direction are formed in the base plate portion 32a. Two screw holes 32e aligned in the left-right direction are formed in the horizontal plate portion 32c. The central member 33 has a generally V-shaped configuration with the opening facing forward when viewed from above. It includes a central base portion 33a, a pair of left and right slope portions 33b extending forward while being spaced apart from each other from bending lines 33f at the left and right ends of the base portion 33a, and a pair of left and right connect portions 33c extending parallel to the base portion 33a and spaced apart from each other from the bending lines 33f at the front ends of each slope portion 33b. A screw hole 33d is formed in the center of the base portion 33a. Two screw holes 33e aligned in the left-right direction are formed in each connect portion 33c. The left-right spacing between the screw holes 33e is equal to the left-right spacing between the two screw holes 31e and the left-right spacing between the two screw holes 32e.

[0023] The stay retaining member 34 is a saddle-shaped metal fitting and has a retaining portion 34a with a generally U-shaped horizontal cross section in the left-right center, and a pair of left and right screw fastening portions 34b extending left and right from the left and right ends of the retaining portion 34a at a distance from each other. Each screw fastening portion 34b has a screw hole 34c formed therein.

[0024] 5, five screws 36 extending forward are disposed on the lower part of the rear panel portion 21 of the panel 20. The five screws 36 are a central screw 36a disposed in the center in the left-right direction and passed through the screw hole 33d of the central member 33, two left screws 36b disposed to the left of the central screw 36a and passed through the elongated holes 31d of the left-side member 31, and two right screws 36c disposed to the right of the central screw 36a and passed through the elongated holes 32d of the right-side member 32.

[0025] As shown in FIGS. 1 and 4 , the blower 40 is attached to the inner surface of the panel 20, which is the surface facing the headrest 3. The blower 40 has a generally hat-shaped cross section that opens toward the panel 20 and a case 41 that extends generally horizontally from the rear panel portion 21 to the side panel portion 22, and a fan (not shown) disposed between the case 41 and the panel 20. The case 41 is disposed so as to overlap the center bead 25 of the panel 20, and upper and lower flanges 42 are fastened to the panel 20 with screws, thereby contributing to increasing the strength and rigidity of the panel 20 in cooperation with the center bead 25. When the fan is activated, the blower 40 draws in air through an intake port 43 at the right end and exhausts the air through an exhaust port 44 at the left end. The exhausted air flows forward along the inner surface of the panel 20 to surround the head of the seated occupant P.

[0026] 1 and 5, the procedure for attaching the partition device 10 to the automobile seat 1 will be described. The left side member 31, right side member 32, and central member 33 of the first bracket 30 are attached to the five screws 36 of the panel 20 to which the air blower 40 is attached. Specifically, first, the central screw 36a is passed through the screw hole 33d of the central member 33 and the nut 37 is tightened to secure the central member 33 to the panel 20. Next, with each of the left screws 36b passed through each of the elongated holes 31d of the left side member 31, the two screw holes 33e of the central member 33 and the two screw holes 31e of the left side member 31 are aligned so that the screw holes 31e are on the front side, and the nuts 37 are tightened onto the left screws 36b to secure the left side member 31 to the panel 20. Next, with each right screw 36c inserted into each elongated hole 32d of the right-side member 32, the two screw holes 33e of the central member 33 and the two screw holes 32e of the right-side member 32 are aligned so that the screw holes 32e are on the front side, and nuts 37 are tightened onto each right screw 36c to secure the right-side member 32 to the panel 20. In this state, the front surface of the horizontal plate portion 31c of the left-side member 31 is brought into contact with the left stay of the pair of left and right stays 3a of the headrest 3 from behind, and the stay pressing member 34 is placed against the left stay from the front so that the left stay fits into the pressing portion 34a, and the screws 35 are fastened to the connecting portion 33c of the central member 33 to secure them. Specifically, the screws 35 that have passed through the screw holes 31e of the horizontal plate portion 31c and the screw holes 34c of the stay pressing member 34 are fastened into the screw holes 33e of the connecting portion 33c. Similarly, the front surface of the horizontal plate portion 32c of the right side member 32 is brought into contact with the right stay of the pair of left and right stays 3a of the headrest 3 from behind, and the stay pressing member 34 is placed against the right stay from the front so that the right stay fits into the pressing portion 34a, and then the screws 35 are fastened to the connecting portion 33c of the central member 33 to fix them. Specifically, the screws 35 that have passed through the screw holes 32e of the horizontal plate portion 32c and the screw holes 34c of the stay pressing member 34 are fastened to the screw holes 33e of the connecting portion 33c.

[0027] The present embodiment configured as described above has the following advantages. The lower bead 23, which has a substantially U-shaped cross section and opens toward the headrest 3, is formed at the bottom of the side panel portion 22 of the panel 20 and extends substantially horizontally from the first bracket 30. This ensures sufficient strength and rigidity of the panel 20 without the need for a separate member such as a reinforcing member. This allows the weight of the partition device 10 to be reduced.

[0028] The panel 20 is made of a transparent resin. Since no separate member, such as a reinforcing member, is attached to the lower portion of the side panel portion 22 of the panel 20, the transparency of the panel 20 makes it less likely that the seated occupant P's lateral visibility will be obstructed. Furthermore, the side panel portion 22 of the panel 20 is formed with an upper bead 24 and a middle bead 25 that extend generally parallel to the lower bead 23 above the lower bead 23, thereby ensuring sufficient strength and rigidity of the panel 20. Additionally, the lower bead 23, the upper bead 24, and the middle bead 25 all have a generally U-shaped cross section that opens toward the headrest 3 and are arranged generally parallel to one another. Therefore, the flow of conditioned air supplied from the front of the automobile seat 1 can be smoothly guided rearward, thereby preventing a decrease in comfort for the rear seats. Additionally, the first bracket 30 has a main body 38 formed by bending a metal plate material along a plurality of parallel bending lines 31f, 32f, 33f, and stay pressing members 34 fastened and fixed to the main body 38 while sandwiching a pair of left and right stays 3a of the headrest 3. This allows the first bracket 30 to have a simple structure.

[0029] FIG. 6 shows another embodiment. This differs from the above embodiment in that the central member 53 of the second bracket 50 is different from the central member 33 of the first bracket 30 of the above embodiment. Components common to the above embodiment are denoted by the same reference numerals and will not be described again. Specifically, the sloped portions 53b of the central member 53 of the second bracket 50 are steeper and rise forward, closer to the front-to-rear direction, than the sloped portions 33b of the central member 33 of the first bracket 30. In other words, the degree to which the pair of left and right sloped portions 53b gradually separate forward from the bending lines 33f at the left and right ends of the base portion 53a is smaller than the degree to which the pair of left and right sloped portions 33b gradually separate forward. The distance between the pair of left and right connecting portions 53c is smaller than the distance between the pair of left and right connecting portions 33c. As a result, the second bracket 50 is applied to a pair of left and right stays 3b of the headrest 3, which have a narrower distance between the stays than the pair of left and right stays 3a of the headrest 3 to which the first bracket 30 is applied. In this case, the distance between the left member 31 and the right member 32 of the second bracket 50 is narrower than that of the first bracket 30, but since the base plate portion 31a has two elongated holes 31d extending in the left-right direction and the base plate portion 32a has two elongated holes 32d extending in the left-right direction, the second bracket 50 can be attached to the panel 20 without any problems. Here, the first bracket 30 and the second bracket 50 each correspond to the "bracket" in the claims.

[0030] Although specific embodiments have been described above, the present invention is not limited to those external appearances and configurations, and various modifications, additions, and deletions are possible within the scope of the present invention. For example, the following can be mentioned.

[0031] 1. In the above embodiment, the lower bead 23 is configured to start from the left end of the rear panel 21 at the bottom of the side panel 22 and extend substantially horizontally forward to near the front end of the side panel 22. However, this is not limiting, and the rear end of the lower bead 23 may be disposed so as to overlap a portion of the rear panel 21.

[0032] 2. The present invention is applied to an automobile seat 1, but may also be applied to seats for airplanes, ships, railway vehicles, etc. [Explanation of symbols]
