Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, the cushion panel is required to have a function of maintaining the sitting posture of the occupant during driving of the vehicle. For this reason, a structure that can suppress deformation of the cushion panel is preferable. However, the cushion panel described in Patent Document 1 may not be able to ensure sufficient rigidity due to the through holes, and there is room for improvement from the viewpoint of suppressing deformation.

[0005] In consideration of the above facts, an object of the present invention is to obtain a vehicle cushion panel and a vehicle seat that can suppress deformation during driving.

Means for Solving the Problems

[0006] The vehicle cushion panel according to claim 1 is disposed inside the seat cushion in a vehicle seat, and includes a bottom wall portion extending in the seat front-rear direction and the seat width direction, and a peripheral wall portion extending upward from both end portions in the seat width direction and the rear end portion of the seat of the bottom wall portion. A panel body configured to include, and extending from the front end portion of the bottom wall portion of the panel body across the peripheral wall portionThe panel body is formed by recessing downwards. The front lateral bead and Furthermore, a through hole is formed in the central portion of the bottom wall, and a pair of front transverse beads are provided on the left and right sides. The inner end of each front transverse bead in the sheet width direction is located on a virtual line extending from the edge of the through hole toward the front of the sheet, and each front transverse bead is inclined so as to gradually move toward the rear of the sheet toward the outside in the sheet width direction when viewed from above. .

[0007] The vehicle cushion panel according to claim 1 comprises a panel body disposed inside the seat cushion of a vehicle seat, the panel body comprising a bottom wall portion and a peripheral wall portion. The bottom wall portion of the panel body extends in the front-rear direction and the seat width direction, and the peripheral wall portion extends upward from both ends of the bottom wall portion in the seat width direction and from the rear end of the seat. This improves rigidity compared to a structure without a peripheral wall portion.

[0008] Furthermore, a lateral bead extends from the front end of the bottom wall of the panel body to the peripheral wall. This increases the rigidity of the connection between the front end of the bottom wall and the peripheral wall, suppressing deformation of the panel body even when a load is applied to this connection when an occupant sits down from the side of the vehicle seat. Also, when an occupant readjusts their position after sitting shallowly on the vehicle seat, a relatively large load is applied to the front end of the panel body, but deformation of the panel body can be suppressed by improving the rigidity of the front end of the panel body with the lateral bead. Moreover, because rigidity is improved by forming the lateral bead, deformation of the panel body can be suppressed without increasing the thickness of the panel body.

[0009] The vehicle cushion panel according to claim 2, in claim 1, further from the bottom wall portion to the peripheral wall portion on the rear side of the seat than the lateral bead A pair (left and right) A lateral bead is formed in the central part.

[0010] In the vehicle cushion panel according to claim 2, the lateral bead in the central part can effectively suppress deformation, particularly in the central part of the peripheral wall in the front-rear direction of the seat.

[0011] The vehicle cushion panel according to claim 3 is, in claim 1, extending from the rear end of the bottom wall portion to the peripheral wall portion A pair (left and right) A rear longitudinal bead is formed.

[0012] The vehicle cushion panel according to claim 3 can suppress deformation of the panel body when the occupant's weight is biased towards the rear side of the panel body relative to the seat.

[0013] The vehicle cushion panel according to claim 4, in claim 1, the peripheral wall portion is composed of side wall portions extending in the front-rear direction of the seat along both ends of the bottom wall portion in the seat width direction, and a rear wall portion connecting the rear ends of the side wall portions in the seat width direction, and extending from the side wall portion to the rear wall portion A pair (left and right) A bead has formed around the perimeter.

[0014] The vehicle cushion panel according to claim 4 can suppress deformation of the panel body when the occupant's weight is biased towards the rear side of the seat and one end in the seat width direction of the panel body.

[0015] The vehicle seat according to claim 5 comprises a vehicle cushion panel according to any one of claims 1 to 4, a seat cushion in which the cushion panel is disposed and which can support the buttocks and thighs of the occupant, and a seat back connected to the rear end of the seat cushion and extending in the vertical direction of the seat and which can support the back of the occupant.

[0016] The vehicle seat according to claim 5 has the effect described in any one of claims 1 to 4. [Effects of the Invention]

[0017] As described above, the vehicle cushion panel and vehicle seat according to the present invention can suppress deformation during driving. [Brief explanation of the drawing]

The seatback 14 extends in the vertical direction of the seat and is capable of supporting the occupant's back from the rear of the seat. It includes a seatback frame and a seatback pad (not shown). A reclining mechanism that allows the angle of the seatback 14 to be changed may be provided at the connection point between the seat cushion 12 and the seatback 14.

[0024] (Cushion panel 10) As shown in Figure 2, the cushion panel 10 is formed by press-forming a metal plate and comprises a panel body 11.

[0025] The panel body 11 is composed of a bottom wall portion 16 and a peripheral wall portion 18. The bottom wall portion 16 extends in the front-to-back direction and the width direction of the sheet, and a substantially rectangular through hole 16A is formed in its central portion.

[0026] The front side of the through hole 16A in the bottom wall portion 16 is a front wall portion 16B formed at a higher position than the general portion of the bottom wall portion 16. The front wall portion 16B extends in the sheet width direction, and both ends of the front wall portion 16B in the sheet width direction are connected to the circumferential wall portion 18.

[0027] The peripheral wall portion 18 extends upward from both ends in the sheet width direction and the rear end of the sheet of the bottom wall portion 16, and is composed of a right side wall portion 18A, a left side wall portion 18B, and a rear wall portion 18C. The right side wall portion 18A extends in the front-rear direction of the sheet along the right side of the through hole 16A and is composed of a curved surface that is continuous with the bottom wall portion 16. Furthermore, the upper end portion of the right side wall portion 18A extends above the sheet beyond the front wall portion 16B and curves toward the right side of the sheet.

[0028] The left side wall portion 18B is formed symmetrically with the right side wall portion 18A. Specifically, the left side wall portion 18B extends in the front-to-back direction of the sheet along the left side of the through hole 16A and is composed of a curved surface that is continuous with the bottom wall portion 16. In addition, the upper end portion of the left side wall portion 18B extends above the sheet beyond the front wall portion 16B and curves toward the left side of the sheet.

[0029] The rear ends of the right side wall 18A and the left side wall 18B are connected in the sheet width direction by the rear wall 18C. The rear wall 18C extends in the sheet width direction along the rear side of the through hole 16A and extends above the sheet beyond the front wall 16B. Furthermore, the right side end of the rear wall 18C is connected to the right side wall 18A by a curved surface that is continuous with the rear wall 18C, and the left side end of the rear wall 18C is connected to the left side wall 18B by a curved surface that is continuous with the rear wall 18C.

[0030] In this embodiment, the panel body 11 has multiple beads formed on it. As an example, in this embodiment, a front horizontal bead 20, a central first horizontal bead 22, a central second horizontal bead 24, a rear vertical bead 26, and a peripheral wall bead 28 are formed. The front horizontal bead 20, the central first horizontal bead 22, the central second horizontal bead 24, the rear vertical bead 26, and the peripheral wall bead 28 are all formed by recessing the panel body 11 downwards.

[0031] (Front lateral bead 20) As shown in Figure 3, a pair of front transverse beads 20 are provided on the front of the panel body 11, one on each side. Specifically, the right front transverse bead 20 is formed at the front and right end of the panel body 11 and extends in the sheet width direction from the front end of the bottom wall portion 16 to the right side wall portion 18A. The inner end of the front transverse bead 20 in the sheet width direction is located on a virtual line extending forward from the right edge of the through hole 16A, and the outer end of the front transverse bead 20 in the sheet width direction is located slightly above the center of the sheet in the vertical direction on the right side wall portion 18A.

[0032] Here, the area 100 enclosed by the dashed line in Figure 3 refers to the area where a large load acts on the panel body 11 when the seating position of the occupant is biased forward when seated in the vehicle seat S. The inner end of the right front transverse bead 20 in the seat width direction is within area 100, and the right portion of the front transverse bead 20 is inclined so as to gradually move towards the rear of the seat in a plan view toward the right side of the seat.

[0033] The left front transverse bead 20 is formed symmetrically with the right front transverse bead 20 with respect to the center line in the sheet width direction of the panel body 11. Specifically, the left front transverse bead 20 is formed at the front and left end of the panel body 11 and extends in the sheet width direction from the front end of the bottom wall portion 16 to the left wall portion 18B. The inner end of the front transverse bead 20 in the sheet width direction is located on a virtual line extending forward from the left edge of the through hole 16A to the front of the sheet and is within region 100. The outer end of the front transverse bead 20 in the sheet width direction is located slightly above the center of the sheet in the vertical direction on the left wall portion 18B, and the left portion of the front transverse bead 20 is inclined so as to gradually move towards the rear of the sheet in a plan view toward the left side of the sheet.

[0034] (Central horizontal bead) As shown in Figure 4, a central first horizontal bead 22 is formed on the rear side of the sheet, beyond the front horizontal bead 20. The central first horizontal bead 22 is provided in pairs, one on each side, slightly forward of the center of the sheet in the front-to-rear direction on the panel body 11. Specifically, the right central first horizontal bead 22 is formed on the right side of the sheet of the through hole 16A and extends in the sheet width direction from the bottom wall portion 16 to the right side wall portion 18A. Furthermore, the central first horizontal bead 22 is shorter in length than the front horizontal bead 20, and is formed to be about one-third the length of the front horizontal bead 20.

[0035] Here, the area 102 enclosed by the dashed line in Figure 4 refers to the area where a large load acts on the panel body 11 when the seating position of the occupant when seated in the vehicle seat S is biased to the left or right. The entire central first transverse bead 22 on the right side is located within the right-side area 102. Specifically, the inner end of the central first transverse bead 22 on the right side in the seat width direction is located at the boundary of the right-side area 102, and the outer end of the central first transverse bead 22 on the right side in the seat width direction is located at the lower end of the right-side wall 18A.

[0036] The left central first horizontal bead 22 is formed symmetrically with respect to the right central first horizontal bead 22 with respect to the center line in the sheet width direction of the panel body 11. Specifically, the left central first horizontal bead 22 is formed on the left side of the sheet of the through hole 16A and extends in the sheet width direction from the bottom wall portion 16 to the left side wall portion 18B. In addition, the central first horizontal bead 22 is shorter in length than the front horizontal bead 20, and is formed to be about one-third the length of the front horizontal bead 20.

[0037] The left central first horizontal bead 22 is entirely located within the left region 102. Specifically, the inner end of the left central first horizontal bead 22 in the sheet width direction is located at the boundary of the left region 102, and the outer end of the left central first horizontal bead 22 in the sheet width direction is located at the lower end of the left wall 18B.

[0038] A second central horizontal bead 24 is formed on the rearward side of the sheet from the first central horizontal bead 22. The second central horizontal bead 24 is provided in pairs on the left and right, slightly rearward from the center of the sheet in the front-rear direction of the panel body 11. Specifically, the right central second horizontal bead 24 is formed on the right side of the sheet of the through hole 16A and extends in the sheet width direction from the bottom wall portion 16 to the right side wall portion 18A. In addition, the second central horizontal bead 24 is shorter in length than the front horizontal bead 20, and is formed to be about one-third the length of the front horizontal bead 20.

[0039] Furthermore, a portion of the right-side central second transverse bead 24 is located within the right-side region 102. Specifically, the inner end of the right-side central second transverse bead 24 in the sheet width direction is located outside region 102 and further inward in the sheet width direction than the right-side central first transverse bead 22. The outer end of the right-side central second transverse bead 24 in the sheet width direction is located at the lower end of the right-side wall portion 18A and further inward in the sheet width direction than the central first transverse bead 22. In addition, the central second transverse bead 24 is inclined towards the rear of the sheet as it extends outward in the sheet width direction in a plan view.

[0040] The second horizontal bead 24 in the left central section is formed symmetrically with respect to the center line in the sheet width direction of the panel body 11, compared to the second horizontal bead 24 in the right central section. Specifically, the second horizontal bead 24 in the left central section is formed on the left side of the sheet of the through hole 16A and extends in the sheet width direction from the bottom wall 16 to the left wall 18B. In addition, the second horizontal bead 24 in the central section is shorter in length than the front horizontal bead 20, and is formed to be about one-third the length of the front horizontal bead 20.

[0041] Furthermore, a portion of the second transverse bead 24 in the left central section is located within the left region 102. Specifically, the inner end of the second transverse bead 24 in the left central section in the sheet width direction is located outside region 102 and further inward in the sheet width direction than the first transverse bead 22 in the left central section. The outer end of the second transverse bead 24 in the left central section in the sheet width direction is located at the lower end of the left wall portion 18B and further inward in the sheet width direction than the first transverse bead 22 in the central section. In addition, the second transverse bead 24 in the central section is inclined towards the rear of the sheet as it moves outward in the sheet width direction in a plan view.

[0042] (Rear vertical bead 26) As shown in Figure 5, a pair of rear vertical beads 26 are provided on the left and right sides at the rear end of the panel body 11. Specifically, the pair of rear vertical beads 26 are each formed on the rear side of the through hole 16A and extend in the front-rear direction of the sheet from the rear end of the bottom wall portion 16 to the rear wall portion 18C. Furthermore, the rear vertical beads 26 are shorter in length than the central first horizontal bead 22 and the central second horizontal bead 24, and the right rear vertical bead 26 and the left rear vertical bead 26 are formed symmetrically with respect to the center line in the sheet width direction of the panel body 11.

[0043] Here, the area 104 enclosed by the dashed line in Figure 5 refers to the area where a large load acts on the panel body 11 when the occupant's seating position on the vehicle seat S is biased towards the rear. The pair of left and right rear vertical beads 26 are each entirely located within area 104. Specifically, the front end of the rear vertical bead 26 is located at the rear end of the bottom wall portion 16, and the rear end of the rear vertical bead 26 is located in the central part of the rear wall portion 18C in the vertical direction of the seat.

[0044] (Surface bead 28) A pair of perimeter wall beads 28 are provided on the left and right sides of the rear end of the panel body 11. Specifically, the right perimeter wall bead 28 is formed at the rear end and rightmost corner of the panel body 11 and extends from the right side wall portion 18A to the rear wall portion 18C.

[0045] The right-side peripheral bead 28 is curved so that, in a plan view, it is positioned towards the front of the sheet as it extends outward in the sheet width direction, and the inner end (left end) of the peripheral bead 28 in the sheet width direction is located within region 104. The outer end (right end) of the peripheral bead 28 in the sheet width direction is located at the rear and upper end of the right-side wall portion 18A.

[0046] The left-side peripheral bead 28 is curved so that, in a plan view, it is positioned towards the front of the sheet as it extends outward in the sheet width direction, and the inner end (right end) of the peripheral bead 28 in the sheet width direction is located within region 104. The outer end (left end) of the peripheral bead 28 in the sheet width direction is located at the rear and upper end of the left-side wall portion 18B.

[0047] (action) Next, the operation of the vehicle seat S equipped with the cushion panel 10 according to this embodiment will be described.

[0048] The cushion panel 10 of this embodiment includes a panel body 11 that is placed inside the seat cushion 12, and the panel body 11 is composed of a bottom wall portion 16 and a peripheral wall portion 18. The bottom wall portion 16 of the panel body 11 extends in the front-rear direction and the width direction of the seat, and the peripheral wall portion 18 extends upward from both ends of the bottom wall portion 16 in the width direction of the seat and from the rear end of the seat. As a result, rigidity is improved compared to a structure without a peripheral wall portion 18.

[0049] Furthermore, as shown in Figure 3, a front lateral bead 20 extends from the front end of the bottom wall portion 16 of the panel body 11 to the side wall portion. This increases the rigidity of the connection portion between the front end of the bottom wall portion 16 and the peripheral wall portion 18, and suppresses deformation of the panel body 11 even when a load is applied to the region 100 when an occupant sits on the vehicle seat S from the side. Also, when an occupant readjusts their position from a shallow sitting position on the vehicle seat S, a relatively large load is applied to the region 100 of the panel body 11, but deformation of the panel body 11 can be suppressed by improving the rigidity of the front end of the panel body 11 with the front lateral bead 20. Moreover, because rigidity is improved by forming the front lateral bead 20, deformation of the panel body 11 can be suppressed without increasing the thickness of the panel body 11.

[0050] Furthermore, in this embodiment, the central first lateral bead 22 and the central second lateral bead 24 are formed on the rear side of the sheet, relative to the front lateral bead 20. This improves the rigidity of the connection portion between the central part of the peripheral wall 18 in the front-rear direction of the sheet and the bottom wall 16, and suppresses deformation of the panel body 11 even when a large load is applied to the region 102 shown in Figure 4.

[0051] Furthermore, in this embodiment, the rear vertical bead 26 particularly improves the rigidity of the connection portion between the rear wall portion 18C and the bottom wall portion 16, and even when a large load is applied to the region 104 shown in Figure 5, deformation of the panel body 11 can be suppressed.

[0052] Furthermore, in this embodiment, the peripheral wall bead 28 improves the rigidity of the connection portion between the right side wall portion 18A and the rear wall portion 18C, and the connection portion between the left side wall portion 18B and the rear wall portion 18C in the peripheral wall portion 18, thereby suppressing deformation of the panel body when the weight of the occupant is biased towards the rear side of the seat and one end in the seat width direction of the panel body 11.

[0053] Furthermore, in this embodiment, the front lateral bead 20, the central first lateral bead 22, the central second lateral bead 24, the rear vertical bead 26, and the peripheral wall bead 28 are formed by recessing the panel body 11 downwards. This eliminates the feeling of foreign objects when an occupant sits on the vehicle seat S, ensuring occupant comfort while suppressing deformation of the panel body 11.

[0054] <Second Embodiment> Next, a vehicle cushion panel 50 according to the second embodiment (hereinafter referred to as "cushion panel 50" as appropriate) will be described with reference to Figure 6. Note that components similar to those in the first embodiment will be denoted by the same reference numerals, and their descriptions will be omitted as appropriate.

[0055] As shown in Figure 6, the cushion panel 50 of this embodiment has the same configuration as the first embodiment, except for the bead.

[0056] A pair of front lateral beads 52 are formed on the front of the panel body 11. The front lateral beads 52 are formed in approximately the same position as the front lateral beads 20 in the first embodiment. However, the front lateral beads 52 differ from the first embodiment in that they are formed by causing a part of the panel body 11 to protrude upward.

[0057] The central first horizontal bead 54, the central second horizontal bead 56, the rear vertical bead 58, and the peripheral wall bead 60 are formed in substantially the same positions as the central first horizontal bead 22, the central second horizontal bead 24, the rear vertical bead 26, and the peripheral wall bead 28 of the first embodiment. Furthermore, the central first horizontal bead 54, the central second horizontal bead 56, the rear vertical bead 58, and the peripheral wall bead 60 differ from the first embodiment in that they are formed by projecting upward a portion of the panel body 11.

[0058] (action) Next, the operation of this embodiment will be explained.

[0059] In this embodiment, all the beads formed on the panel body 11 protrude upward. This suppresses interference with components below the panel body 11. Other functions are the same as in the first embodiment.

[0060] Although the cushion panels 10 and 50 have been described above in relation to the first and second embodiments, it goes without saying that the present invention can be implemented in various forms without departing from the spirit of the invention. For example, in the first embodiment described above, a configuration was adopted in which a front lateral bead 20, a central first lateral bead 22, a central second lateral bead 24, a rear vertical bead 26, and a peripheral wall bead 28 were formed, but the invention is not limited to this, and a configuration in which only some of the beads are formed may be adopted. That is, a configuration in which only the front lateral bead 20, the rear vertical bead 26, and the peripheral wall bead 28 are formed may be adopted, or a configuration in which only the front lateral bead 20, the central first lateral bead 22, and the central second lateral bead 24 are formed may be adopted. Furthermore, a configuration in which only the front lateral bead 20 is formed may be adopted.

[0061] Furthermore, the shapes of the front lateral bead 20, the central first lateral bead 22, the central second lateral bead 24, the rear vertical bead 26, and the peripheral wall bead 28 are not particularly limited and may be other shapes. For example, the central first lateral bead 22 and the central second lateral bead 24 may be formed to be approximately the same length as the front lateral bead 20. Moreover, although a pair of front lateral beads 20 are formed on the left and right sides, the invention is not limited to this and may be a single lateral bead extending from the right side wall 18A to the left side wall 18B via the front wall 16B.

[0062] Furthermore, although a substantially rectangular through-hole is formed in the panel body 11 in the above embodiment, the invention is not limited to this. For example, a substantially circular through-hole may be formed in the panel body 11. Alternatively, a panel body 11 without a through-hole may be used, but forming a through-hole is preferable from the viewpoint of weight reduction.

[0063] The following additional information is disclosed regarding the above embodiment.

[0064] (Note 1) A panel body comprising a bottom wall portion positioned inside the seat cushion of a vehicle seat and extending in the front-rear direction and the width direction of the seat, and peripheral wall portions extending upward from both ends of the bottom wall portion in the width direction of the seat and from the rear end of the seat, A front transverse bead extending from the front end of the bottom wall portion to the side wall portion of the panel body, A vehicle cushion panel having [a certain feature].
