Description

Technical Field

[0001] This utility model belongs to the field of automotive seat design, and specifically relates to an optimization tooling for automotive seat side panels. Background Technology

[0002] The development of intelligent connectivity in passenger vehicles is currently booming; however, there is a lack of research on interior comfort and human-machine interface, resulting in insufficient performance in this area. For passenger vehicle seats, the overall support and comfort of the seat largely depend on its design. Improper design of the necessary support channels and seams can negatively impact the overall comfort experience for passengers, thus affecting vehicle sales.

[0003] The seat side panel is a sub-part on the side of the seat, mainly used to cover the frame and house the seat adjustment mechanism. When passengers get on and off the vehicle and sit down, their legs come into contact with the side panel, creating contact pressure between the side panel and their thighs, which may cause discomfort. Therefore, it is necessary to optimize the parameters of the side panel before starting the mold. However, there is currently a lack of devices for optimizing the comfort-related parameters of the side panel. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing technology lacks a device for optimizing the comfort-related parameters of the side panels.

[0006] By adopting the above solution, since the connection position of the upper and lower plates is adjustable, the contact between the side plate and the passenger's legs under different heights and / or widths can be simulated by adjusting the vertical and / or front-to-back position relationship of the upper plate relative to the lower plate. This allows for the acquisition of side plate comfort-related parameters, and optimization can prevent the side plate from causing leg discomfort during passenger boarding and alighting. Furthermore, an aesthetic assessment can be performed after adjustment to obtain side plate aesthetic parameters. In summary, the seat side plate optimization fixture provided by this invention can obtain parameters that significantly affect the comfort and aesthetics of the side plate. By further optimizing these parameters using mathematical methods, optimal dimensional parameters that balance comfort and aesthetics can be achieved during forward development, providing important guidance in the part design stage.

[0051] The seat side panel is a sub-part on the side of a car seat, mainly used to cover the frame and house the seat adjustment mechanism. When passengers get in and out of the car and sit down, their legs come into contact with the side panel, creating contact pressure between the side panel and their thighs, which may cause discomfort. Therefore, it is necessary to optimize the parameters of the side panel before starting the mold; however, there is currently a lack of devices for optimizing the comfort-related parameters of the side panel.

[0052] To address the aforementioned problems, this utility model provides a seat side panel optimization fixture, comprising a lower plate for fixed connection to the seat frame at the lower part of the seat side, and an upper plate connected to the upper end of the lower plate. The connection between the upper and lower plates has multiple movable fixing points, and a first locking member is provided to lock the connection between the upper and lower plates at any one of these movable fixing points. By connecting at different movable fixing points, the position of the upper plate relative to the lower plate can be adjusted along the height direction and / or length direction of the seat. This seat side panel optimization fixture can be applied to comfort optimization of seats in actual vehicle projects during development. In use, the seat side panel optimization fixture is installed on an initial seat verification prototype. Because the connection position of the upper and lower plates is adjustable, the fore-and-aft and vertical position relationship of the upper plate relative to the lower plate can be adjusted to simulate different heights of the side panel and the contact situation of the occupant's thighs at the highest point, thereby optimizing the side panel to achieve a balance between comfort and aesthetics.

[0053] To better understand the seat side panel optimization tooling provided in this application, the structure of the side panel optimization tooling will be described in detail below with reference to the accompanying drawings.

[0054] The optimized tooling for the side panel of the seat provided by this utility model is installed on a seat verification prototype during use. The seat prototype simulates a real vehicle seat and has a seat frame. Figures 1-2 As shown, the seat side panel optimization fixture 1 includes a lower plate 10, an upper plate 11, and a first locking member 12. Wherein... Figure 1 A schematic diagram of the structure of the seat side panel optimization tool 1 set on the side of the seat 2 is shown.

[0055] like Figures 1-2 As shown, the lower plate 10 is used to fixably connect to the seat frame at the lower part of the left and / or right side of the seat 2. Since the lower part of the seat side generally does not directly contact the occupant, it does not directly affect the seat comfort. The side plate at this position does not need to be adjusted relative to the seat. The lower plate 10 corresponds to this position, thus fixing the lower plate 10 relative to the seat 2. Specifically, the lower plate 10 and the side of the seat 2 can be fixedly connected by adhesive, or by fasteners, snap-fit ​​components, etc. Preferably, the lower plate 10 and the side of the seat 2 are detachably connected, making it easy to remove the side plate optimization fixture 1 after use and reuse it for other seats. In one specific embodiment, such as Figure 3a , Figure 3b and Figure 4 As shown, the upper end of the lower plate 10 and the seat frame are fixedly connected by fasteners, specifically as follows: Figure 3a and Figure 4 As shown in the diagram, the first point 21 is connected, and the lower end of the lower plate 10 is fixedly connected to the seat frame on the lower side of the seat 2 via a snap-fit ​​connector. Specifically, this can be achieved by... Figure 3bThe second point 22 shown is connected, wherein the fastener can specifically be a bolt, and the snap-fit ​​can specifically be a plastic snap-fit.

[0056] like Figures 1-2 As shown, the upper end of the upper plate 11 is mounted on the seat frame on the upper side of the seat 2. The lower end of the upper plate 11 is connected to the upper end of the lower plate 10, and the connection between the upper plate 11 and the lower plate 10 has multiple movable fixing points. The first locking member 12 is used to lock the connection between the upper plate 11 and the lower plate 10 at any one of the movable fixing points, so that the upper plate 11 is fixed relative to the lower plate 10 at that movable fixing point. By connecting the upper plate 11 and the lower plate 10 at different movable fixing points, the position of the upper plate 11 relative to the lower plate 10 can be adjusted along the height direction and / or the length direction of the seat 2.

[0057] Specifically, matching sliding structures, such as slide rails and sliders, can be provided at the lower end of the upper plate 11 and the upper end of the lower plate 10, respectively, so that the upper plate 11 can slide relative to the lower plate 10 along the height direction and / or the length direction of the seat 2. The first locking member 12 is a member that can restrict relative sliding, such as a limiting pin, so that the upper plate 11 slides relative to the lower plate 10 to one of a number of set positions and is locked by the first locking member 12. These set positions are multiple moving and fixing points. Alternatively, pin holes can be provided at the lower end of the upper plate 11 and the upper end of the lower plate 10, wherein multiple pin holes are provided at the lower end of the upper plate 11 or the upper end of the lower plate 10 and are distributed along the height direction and / or the length direction of the seat 2. The first locking member 12 is a matching pin, so that after some of the pin holes on the plate with multiple pin holes are aligned with the pin holes on the other plate, the pin is inserted for fixing, forming a moving and fixing point.

[0058] It should be noted that the connection between the lower end of the upper plate 11 and the upper end of the lower plate 10 can change the position of the upper end of the upper plate 11 relative to the upper side of the seat 2 when the moving and fixing points are changed. To achieve this change, the upper end of the upper plate 11 can abut against the seat frame, or an adjustable connecting component can be used to connect the upper end of the upper plate 11 to the upper side of the seat 2. Furthermore, the side panel optimization fixture 1 is used to simulate the structure of the side panel of an actual car seat. Therefore, in addition to the structure located on the side of the seat 2, the side panel optimization fixture may also include a portion located next to the upper end of the seat 2 to more closely approximate the actual side panel, as shown below. Figure 2 The upper plate 11 structure also includes Figure 2 The upper and middle section; and the upper plate 11 can also be designed into different shapes according to the actual appearance of the side plate.

[0059] This utility model's seat side panel optimization fixture can be applied to comfort optimization during the development of seats in actual vehicle projects. In use, the seat side panel optimization fixture 1 is installed on an initial seat verification prototype. Since the connection position of the upper and lower panels is adjustable, the vertical and / or front-to-back position of the upper panel 11 relative to the lower panel 10 can be adjusted to simulate the contact between the side panel and the passenger's legs under different heights and / or widths, thus obtaining side panel comfort-related parameters. After optimization, the side panel avoids leg discomfort during passenger boarding and alighting. Furthermore, an aesthetic assessment can be performed after adjustment to obtain side panel aesthetic parameters. In summary, using the seat side panel optimization fixture provided by this utility model can obtain parameters that significantly affect the comfort and aesthetics of the side panel. By using mathematical methods to optimize these parameters, optimal dimensional parameters that balance comfort and aesthetics can be achieved during forward development, providing important guidance in the part design stage.

[0060] In one specific embodiment of this utility model, such as Figure 2 , Figure 3a and Figure 4 As shown, the first locking member 12 includes a lower pin ( Figure 2 121 and 122); wherein the upper end of the lower plate 10 is provided with a lower plate pin receiving hole that matches the lower pin ( ). Figure 3a and Figure 4 (1011 and 1021 in the text) The shape or number of holes varies depending on the specific structure of the lower pin. If the pin body is a cylindrical pin, the matching lower plate pin connection hole is a round hole; if the pin body is two cylindrical pins, the matching lower plate pin connection hole is two round holes. The lower end of the upper plate 11 is provided with multiple upper plate lower pin connection holes distributed along the height direction of the seat 2 and / or along the length direction of the seat 2. Figure 2 In the figures 1111 and 1121), the shape of the upper plate lower pin connection hole matches the lower pin, and the number of upper plate lower pin connection holes is greater than the number of lower plate pin connection holes. These holes are distributed along the height direction or length direction of the seat 2, or both. The lower pin can pass through at least one upper plate lower pin connection hole and one lower plate pin connection hole to fix the upper plate 11 and lower plate 10 at a movable fixed point. After matching the positions of different upper plate lower pin connection holes and lower plate pin connection holes, the lower pin is inserted for fixation, allowing adjustment of the position of the upper plate 11 relative to the lower plate 10 along the height direction and / or length direction of the seat 2. The upper plate 11 and lower plate 10 are connected by a pin, a simple connection and adjustment method that facilitates disassembly.

[0061] It should be noted that the length direction of seat 2 refers to the length direction of the car when seat 2 is installed at the rear of the car. Figure 1The X direction of seat 2 refers to the width direction of the car when seat 2 is positioned at the rear of the car. Figure 1 The Y-direction of seat 2 refers to the height direction of the car when seat 2 is positioned at the rear of the car. Figure 1 (in the Z direction).

[0062] In one specific embodiment of this utility model, such as Figures 4-6 As shown, the lower end of the upper plate 11 is provided with a first slot 113 for insertion into the upper end of the lower plate 10, thereby restricting the movement of the upper plate 11 relative to the lower plate 10 along the width direction of the seat 2. It should be noted that when the lower end of the upper plate 11 is connected to the upper end of the lower plate 10, the lower end of the upper plate 11 is further away from the seat frame relative to the upper end of the lower plate 10. Specifically, as... Figure 4 As shown, the first slot 113 can be provided with multiple downward-facing L-shaped structures on the inner side of the lower end of the upper plate 11 (the side connected to the seat frame), with the upper end connected to the inner side of the upper plate 11 to form multiple slot structures so that the upper end of the lower plate 10 can be inserted into the slots; in addition to the method shown in the figure, the first slot 113 can also be a slot continuously provided along the lower end of the upper plate 11, but it should not obstruct the insertion of the lower pin into the pin hole. It should be noted that if the position of the upper plate 11 relative to the lower plate 10 can be adjusted along the height direction of the seat 2, the deepest position after the upper end of the upper plate 11 is inserted into the first slot 113 should be at or below the lowest position that the upper plate 11 can be adjusted in the height direction, so that the depth of the slot will not hinder the adjustment of the upper plate 11 in the height direction.

[0063] In one specific embodiment of this utility model, such as Figure 2 As shown, the upper plate 11 includes an upper body 111 and an upper front end 112. The upper body 111 is disposed on the upper part of the side of the seat 2, and the upper front end 112 is disposed on the upper front part of the seat 2 (corresponding to the upper part of the side of the seat 2) adjacent to the side of the seat 2, that is, one end of the upper body 111 and one end of the upper front end 112 are connected and form an angle of about 90 degrees. The lower plate 10 includes a lower body 101 and a lower front end 102. The lower body 101 is disposed on the lower part of the side of the seat 2, and the lower front end 102 is disposed on the lower front part of the seat 2 (corresponding to the lower part of the side of the seat 2) adjacent to the side of the seat 2, that is, one end of the lower body 101 and one end of the lower front end 102 are connected and form an angle of about 90 degrees.

[0064] like Figure 2 , Figure 3a and Figure 4As shown, the lower plate pin connection hole includes a first lower plate pin connection hole 1011 disposed on the lower main body 101 and a second lower plate pin connection hole 1021 disposed on the lower front end 102; the multiple upper plate lower pin connection holes include multiple first upper plate lower pin connection holes 1111 disposed on the upper main body 111 and multiple second upper plate lower pin connection holes 1121 disposed on the upper front end 112; wherein the multiple first upper plate lower pin connection holes 1111 are distributed along the height direction and the length direction of the seat 2 respectively, the multiple second upper plate lower pin connection holes 1121 are distributed along the height direction of the seat 2, and the positions of the multiple first upper plate lower pin connection holes 1111 and the multiple second upper plate lower pin connection holes 1121 distributed along the height direction of the seat 2 correspond. The lower pin includes a first lower pin 121 and a second lower pin 122; the first lower pin 121 can pass through at least one first upper plate lower pin connection hole 1111 and a first lower plate pin connection hole 1011 to connect the upper body 111 and the lower body 101 and restrict the movement of the upper plate 11 relative to the lower plate 10 along the length direction of the seat 2; the second lower pin 122 can pass through at least one second upper plate lower pin connection hole 1121 and a second lower plate pin connection hole 1021 to connect the upper front end 112 and the lower front end 102 to restrict the movement of the upper plate 11 relative to the lower plate 10 along the width direction of the seat 2.

[0065] In one specific embodiment of this utility model, such as Figure 2 As shown, the first lower pin 121 includes a plurality of first pins and a first connecting plate. The first connecting plate is connected to one end of the plurality of first pins. The number of first lower plate pin holes 1011 is equal to the number of first pins. The number of rows of the plurality of first upper plate pin holes 1111 distributed along the length of the seat 2 is greater than the number of first pins. The second lower pin 122 includes a plurality of second pins and a second connecting plate. The second connecting plate is connected to one end of the plurality of second pins. The number of second lower plate pin holes 1021 is equal to the number of second pins.

[0066] Specifically, such as Figure 2 As shown, taking an example where there are two of each of the multiple first pins and multiple second pins, the first lower plate pin connection hole 1011 and the second lower plate pin connection hole 1021 are both set along the length direction of the seat 2. The multiple first upper plate lower pin connection holes 1111 are distributed in multiple rows along the height direction of the seat 2, such as 2 rows, 3 rows, 4 rows, 5 rows, etc. The multiple first upper plate lower pin connection holes 1111 are distributed in multiple columns along the length direction of the seat 2 and the number of columns is greater than 2, such as 3 columns, 4 columns, 5 columns, 6 columns, etc. The multiple second upper plate lower pin connection holes 1121 are distributed in multiple rows along the height direction of the seat 2, and the number of rows and heights are the same as the multiple rows of the multiple first upper plate lower pin connection holes 1111 distributed along the height direction of the seat 2.

[0067] When using, such as Figure 10As shown, aligning the first lower plate pin holes 1011 of a certain row with the first upper plate lower pin holes 1111, and simultaneously aligning the second lower plate pin holes 1021 of the corresponding row with the second upper plate lower pin holes 1121, allows adjustment of the position of the upper plate 11 relative to the lower plate 10 along the height direction of the seat 2. Aligning the first lower plate pin holes 1011 of two rows with the first upper plate lower pin holes 1111, while simultaneously moving the second upper plate lower pin holes 1121 away from the second lower plate pin holes 1021, while keeping the corresponding row's position unchanged, allows adjustment of the position of the upper plate 11 relative to the lower plate 10 along the length direction of the seat 2. After determining the alignment position, inserting the first lower pin 121 and the second lower pin 122 respectively, fixes the upper plate 11 and the lower plate 10 at the movable fixing point. Different numbers of movable fixing points can be obtained depending on the number of first lower plate pin holes 1011, such as... Figure 2 The diagram shows 24 first lower plate pin holes 1011 arranged in 4 rows (forming 4 height positions) and 6 columns (forming 5 length positions), which can form 20 movable fixing points.

Specifically, as Figure 2As shown, the upper plate pin hole 1112 can be located above the first upper plate lower pin hole 1111, and the spacing of the upper plate pin holes 1112 along the height direction of the seat 2 is the same as the spacing of the first upper plate lower pin holes 1111 along the height direction. The bracket 24 is generally made of steel wire, and the upper pin 123 is provided so that the upper plate 11 is connected to the seat frame by the upward support force provided by the bracket 24 to provide strength support, restrict the downward movement of the upper plate 11, and also prevent the upper plate 11 from collapsing due to being sat on by passengers.

[0070] In one specific embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the upper pin 123 is plate-shaped, and the pin hole 1112 on the upper plate is a long strip-shaped hole adapted to the plate shape; the upper pin 123 is preferably made of Q235 steel.

[0071] In one specific embodiment of this utility model, such as Figure 4 and Figure 8 As shown, a second slot 114 is provided on the upper end of the upper plate 11 near the seat frame. The slot 114 has an opening facing downwards and the width of the slot matches the bracket 24. It is used to insert into the bracket 24 to limit the movement of the upper plate 11 relative to the bracket 24 in the width direction of the seat 2.

[0072] In one specific embodiment of this utility model, such as Figure 3a , Figure 3b , Figure 9 and Figure 10 As shown, the lower plate 10 includes a lower main body 101 and a rear portion 103, and may also include a lower front portion 102. The rear portion 103 is used for fixed connection with the seat frame at the rear side of the seat 2. In one specific embodiment, the rear portion 103 of the lower plate 10 is detachably fixed to the seat frame at the rear of the seat 2 by fasteners such as bolts. Specifically, it can be... Figure 3a and 3b The third site 23 is shown in the diagram.

[0073] like Figures 1-2 , Figure 9 and Figure 10As shown, the seat side panel optimization fixture 1 also includes a rear plate 13 and a second locking member 14. The upper end of the rear plate 13 is hinged to the upper end of the rear part 103; the lower end of the rear plate 13 is connected to the lower end of the rear part 103 and has multiple rotational fixing points. The second locking member 14 is used to lock the connection between the lower end of the rear plate 13 and the lower end of the rear part 103 at any one of the rotational fixing points, so that the rear plate 13 is fixed relative to the rear part 103 at that rotational fixing point. The lower end of the rear plate 13 and the lower end of the rear part 103 are connected at different rotational fixing points, allowing the position of the lower end of the rear plate 13 relative to the lower end of the rear part 103 to be adjusted along the rotation direction with the hinge position of the upper end of the rear plate 13 as the pivot. It should be noted that, as... Figure 2 As shown, the rear panel 13 simulates the rear of an actual side panel, and its upper end can be provided with a plate that is inclined upwards, located next to the rear of the seat 2. As the position of the lower end of the rear panel 13 relative to the lower end of the rear part 103 can be adjusted along the rotation direction with the hinge position of the upper end of the rear panel 13 as the pivot point, the angle of the inclined plate changes. This is used to test the effect of the position of the upper end of the side panel rear panel 13 on the comfort of the human thigh or buttocks. The shape of the rear panel 13 can be set as needed, such as... Figure 9 As shown, it has an irregular shape.

[0074] Specifically, the lower end of the rear plate 13 and the lower end of the rear part 103 can be matched with an arc-shaped sliding connection structure, such as a slide rail and slider cooperation structure, and a corresponding locking mechanism can be provided to lock the relative position of the lower end of the rear plate 13 and the lower end of the rear part 103, thereby restricting the relative rotation of the upper end of the rear plate 13. The lower end of the rear plate 13 and the lower end of the rear part 103 can also be adjusted by matching a pin with a pin hole.

[0075] In one specific embodiment of this utility model, such as Figure 2 and Figure 9 As shown, the seat side panel optimization fixture 1 also includes a pin 15, and the second locking component 14 includes a third pin 141; the upper end of the rear plate 13 is provided with a rear upper pin connection hole 131, and the lower end of the rear plate 13 is provided with multiple rear lower pin connection holes 132, which are distributed along an arc centered on the rear upper pin connection hole 131; the upper end of the rear part 103 is provided with a rear upper pin connection hole 1031, as shown in the figure. Figure 3a As shown, the lower end of the rear part 103 is provided with a rear lower pin receiving hole 1032; wherein, as Figure 2 and Figure 9 As shown, the pin 15 passes through the pin hole 131 on the rear plate and the upper pin hole 1031 on the rear part, so that the upper end of the rear plate 13 is hinged to the upper end of the rear part 103; the third pin 141 passes through any one of the lower pin holes 132 on the rear plate and the lower pin hole 1032 on the rear part, so that the lower end of the rear plate 13 is fixedly connected to the lower end of the rear part 103 at a rotational fixed point.

[0076] Specifically, such as Figure 2 and Figure 9 As shown, one end of the pin 15 can also be provided with a plate-like structure, and the other end is used to pass through the pin hole 131 on the rear plate and the upper rear pin hole 1031; the third pin 141 can specifically be a pin.

[0077] When using, such as Figure 2 , Figure 9 and Figure 10 As shown, the lower plate 10 is first installed on the seat frame. Then, the pin hole 131 on the rear plate is aligned with the upper pin hole 1031 at the rear, and the pin 15 is inserted to rotatably connect the rear plate 13 and the lower plate 10. After rotating the lower end of the rear plate 13 and adjusting the angle of the upper end of the rear plate 13, one lower pin hole 132 on the rear plate is aligned with the lower pin hole 1032 at the rear, and the third pin 141 is inserted to fix the rear plate 13 and the rear part 103 at a rotation fixing point. The number of pin holes 131 on the rear plate can be set as needed, and the number of rotation fixing points can be generated by the number of pin holes 131 on the rear plate. For example, the attached figure of this embodiment shows 5 pin holes 131 on the rear plate, thus providing 5 rotation fixing points.

[0078] In one specific embodiment of this utility model, a plurality of rear plate lower pin holes 132 are distributed at intervals of 5°-10° along an arc centered on the rear plate pin holes 131, preferably 5°.

[0079] It should be noted that the upper plate 11 is positioned to avoid the rear part 103 and the rear plate 13, so that the movement adjustment of the upper plate 11 relative to the lower plate 10 and the rotation adjustment of the rear plate 13 relative to the lower plate 10 do not affect each other.

[0080] The optimized tooling for the seat side panel provided by this utility model Figure 10 The dashed arrows indicate the adjustable direction. Specifically, adjusting the fore-and-aft and vertical position of the upper plate 11 relative to the lower plate 10 can simulate different heights of the side panel and the contact of the highest point with the occupant's thighs. When setting the rear plate 13, adjusting the rotation of the upper plate 11 relative to the lower plate 10 can test the impact of the position of the upper end of the rear part 103 of the side panel on the comfort of the posterior thigh or buttocks. It can also obtain information on the aesthetics of adjusting the rear seat side panel. Further optimization of the parameters can be achieved using mathematical methods, such as the DOE method for styling parameter optimization.

[0081] The following example illustrates the process of using the seat side panel optimization fixture 1 provided by this utility model to adjust and obtain different parameters, and using Minitab to optimize the parameters. The angle of the upper end of the rear panel 13, the height of the side panel, and the horizontal position of the highest point are used as continuous influence factors. In addition, the side panel styling style is added as a categorical influence factor, and response surface analysis is performed.

[0082] First, create a response surface methodology, selecting Box-Behnken design, setting the continuous factor to 3 and the categorical factor to 1, then adjust the continuous factor to 3 levels; for the side panel plate 11, also create 3 rapid prototypes according to the desired design style, as detailed below. Figures 11a-11c As shown, levels 1, 2, and 3 are used as categorical influencing factors. The differences in their upper surface shapes will affect the actual comfort (leg-gripping sensation) and aesthetic appeal. The specific degree of influence is mainly determined by the subjective scores of the tested volunteers. For the actual sample, the X-axis position of the upper plate can be taken as the center position, the level before the center, and the level after the center, defined as [-1, 0, 1]. The Z-axis position of the upper plate can be taken as the two levels below the highest, with the level below the highest and the highest position defined as [-1, 0, 1]. The first, second, and third levels of the side panel and rear plate 13 are defined as [-1, 0, 1]. The three side panel shapes are set as classification factors [1, 2, 3]. A response surface design is created, and the design table is shown below. Figure 12 A total of 45 groups of experiments were conducted.

[0083] Then, a subjective assessment of human comfort was conducted based on the experimental design results. This embodiment used a 5-point scale. The side panel positions were adjusted according to the experimental design results, and experimenters subjectively scored the discomfort caused by the side panels at each position. The 5%, 50%, and 95% quartile body types were required to participate in the scoring, and the appearance of the adjusted side panel was also subjectively scored. The results were then obtained. Response regression surface analysis was performed, and the scores for each occupant and the subjective appearance scores were used as the response.

[0084] like Figure 13 The results of significance factor calculation using the variance method are shown for one set of data. For example... Figure 13 As shown in the table, A represents the Z-axis height, B represents the X-axis position, C represents the rear panel angle (13°), and D represents the styling selection. Since the F-value of the side panel's Z-axis height is much larger than other factors, it can be concluded that the side panel height has the greatest impact on leg comfort. The regression equation calculation results for the three continuous influencing factors and the subjective comfort score under the three styling conditions are shown in the appendix. Figure 14 As shown in the table.

[0085] After completing the regression equation and determining the significance of influencing factors, a response optimizer was used to calculate the response. The volunteer's subjective comfort score and styling score were amplified separately. The weights of comfort and styling can be adjusted according to the focus of part development; in this embodiment, each weight is set to 1. The response optimizer calculation results are attached. Figure 15 As shown, the optimal height position is -0.9394, the optimal horizontal position is 0.1515, and the optimal angle of the side panel and rear panel 13 is 0.5556.

[0086] In this experiment, the side panel was adjusted in increments of 8mm along the seat height and 20mm along the seat length, and the rear panel 13 was rotated in increments of 5°. The current design corresponds to a height of 1, a horizontal position of 0, and an angle of 1 for the rear panel 13. According to the calculation results, for this experimenter, the optimal solution to balance appearance and comfort should reduce the height of the side panel by 15.5mm, the highest point by 3.03mm, and reduce the upper angle of the rear panel 13 by 2.2°.

[0087] The present invention provides a seat side panel optimization tooling for optimizing seat side panels. It can adjust some dimensional parameters that have a significant impact on the comfort of the side panel, and then calculate the optimal solution by using mathematical methods, thereby achieving the optimal dimensional parameters that balance comfort and aesthetic appearance in forward development. It has an important guiding role in the part design stage.
