Description

The invention relates to a device and a method for testing at least one seat component for a motor vehicle. Methods for testing soft-elastic foams, or elastomers, are already extensively and in detail published by the German Institute for Standardization (DIN). For example, DIN 53579 describes a method for determining the indentation hardness of molded soft foams. DIN EN ISO 2439 specifies various methods for determining indentation hardness. DIN EN ISO 3385 discloses a method for determining thickness loss and hardness loss in soft-elastic foams. DIN ISO 3386-1 describes a method for determining the compressive stress-deformation properties of soft-elastic foams. Furthermore, DIN ISO 23529 specifies general methods for the production, measurement, marking, storage, and conditioning of elastomer specimens for use in physical tests, as well as the preferred test conditions. The object of the invention is to develop a testing method by which the comfort of a vehicle occupant sitting on a seat of a motor vehicle can be assessed as objectively as possible during human movements of the vehicle occupant. This problem is solved by the device according to the invention for testing at least one seat component for a motor vehicle and by the method according to the invention. Advantageous embodiments of the invention are the subject of the dependent claims and the description. The device according to the invention for testing at least one seat component for a motor vehicle comprises a slide that is translationally movable along a first direction relative to a frame and along a guide device, which has a first receiving area for receiving a first seat component in a first intended receiving position, a spring device supported on a frame of the device by means of which the slide can be deflected in the first direction, a plunger which can be moved in a second direction transverse to the first direction towards the receiving area, and a detection device which has a sensor embedded in an elastomer which is arranged on a side of the plunger facing the first receiving area, so that measurement data and / or pressure and / or shear can be measured within the sensor embedded in the elastomer by means of the sensor. The carriage is mounted on the frame of the device so that it can move in the first direction. For example, the carriage is mounted so that it can move or adjust in a first plane, particularly along a straight line, relative to the frame. The carriage is mounted on the frame by a guide device arranged on the frame. One possible design of the guide device is a mandrel extending in the first direction, which is arranged on the frame. For example, the carriage can have at least one guide sleeve, in particular a sliding sleeve, which surrounds the mandrel and can slide along it. Due to its adjustable mounting on the frame, the carriage is movable in the direction of extension of the mandrel relative to the mandrel and relative to the frame.Since the guide device directs the translational movement of the carriage, the first direction is determined by the design, in particular the extension, of the guide device. The device further comprises the spring assembly by means of which the slide can be set into a preferably translational movement relative to the frame. The spring assembly includes at least one spring. For example, this spring is arranged to enclose the mandrel. This means that the mandrel is, for example, arranged at least substantially within the spring. The spring can, for example, be arranged at one end against the frame, while at its other end it rests against the slide, in particular the guide sleeve. In particular, the spring can be pre-tensioned. The first receiving area of ​​the slide, which is designed to receive the first seat component in the intended receiving position, can, for example, be designed such that the first seat component can be fixed at least in a second plane formed by the first receiving area, in particular on a straight line oriented in the first direction relative to the slide. This can be achieved, for example, by a positive fit between the receiving area and the first seat component held within it. Alternatively or additionally, a holding device can be provided which reduces or prevents relative movement in the first direction between the first seat component and the slide during a test situation. The first receiving area can be provided, for example, by a rigid plate or by a spring device. For example, the receiving area extends, in particular, parallel to the guide device. The plunger, equipped with the detection device, is movable towards the first detection area in a second direction. This second direction is perpendicular to the first direction. In particular, the second direction is at least substantially perpendicular to the first direction. This means that the first direction extends at right angles to the second direction. The plunger's shape is not restricted. Furthermore, the plunger is arranged on the device such that it can press onto or into the first or another seating component for the vehicle with varying force. Alternatively, the first direction can extend obliquely to the second direction, and the plunger can thus move obliquely towards the first plane in which the slide is adjustable. The detection device comprises the sensor embedded in the elastomer, which in particular consists of at least one individual sensor. For example, the measurement data that can be generated by the sensor is based on a change in a measurable capacitance due to deformations of dielectric elastomers in the individual sensors. In particular, the detection device is arranged on a side of the stamp that faces the first detection area. The invention is based in particular on the realization that there is currently no suitable, reproducible measuring device that can simulate and measure the loads of a vehicle occupant in a vehicle seat corresponding to human movements. Currently, there are only measuring devices and methods that focus on the material properties of the "hat" of a vehicle seat. The hat is defined, for example, as the part of a vehicle seat that corresponds to a structure mounted on a metal frame. This includes components such as foam, springs, and the seat cover. Measurement methods for investigating material properties include, for example, foam testing and cover testing. Currently, there are no measurement methods that examine individual seat components for their influence on the load placed on vehicle occupants by human movement. Therefore, no measurement method exists that considers material requirements, human comfort requirements, physiological demands, and technical feasibility. In contrast, the device according to the invention allows individual components of the hat's circumference to be examined under laboratory conditions, both dependently and independently. The device enables independent or dependent investigations of the loads occurring in the detection unit as a result of simulated human movements, such as sinking, longitudinal and transverse movements. The human movements are simulated by the method used with the device, and the loads occurring in the detection unit during testing of a vehicle occupant are measured using objective parameters such as pressure, shear, and / or strain. Both static and dynamic analyses are possible. An independent investigation means that individual materials are tested. For example, different foams can be examined with regard to their thickness or hardness. Translational movements of the human body can be simulated using a catapult function provided by the spring mechanism. In a dependent study, at least two different components of the hat circumference are tested together. Dependencies and interactions between the individual components can then be examined very precisely using appropriate sensors. The device according to the invention enables measurements to be carried out for package optimization. Package optimization means that the optimization of a vehicle seat's comfort does not focus on individual seat components, but rather on the interaction of several components. For example, it is used to examine how the loads on vehicle occupants simulated by the detection device behave during human movements in a vehicle seat depending on different combinations of seat components. Advantageously, the guide device can be aligned at different angles relative to the frame. In other words, the guide device is adjustable to different angles relative to the frame. Consequently, the carriage, which is adjustable along the guide device in the first direction, can also be aligned at different angles relative to the frame. The first direction, which describes the translational movement of the carriage, also depends on the orientation of the guide device, since the guide device enables the carriage to be guided in a translational movement along this first direction. If the guide device is arranged at an angle of, for example, 10 degrees relative to the frame, then the first direction along the guide device also extends at an angle of 10 degrees relative to the frame. In an advantageous embodiment of the invention, the first receiving area can be aligned at different angles relative to the guide device. This means that the first receiving area can be arranged at different angles relative to the guide device. For example, a second plane formed by the first receiving area extends obliquely or parallel to the orientation of the guide device and consequently also obliquely or parallel to the first direction. In particular, the receiving area is designed such that the angle at which it is aligned relative to the guide device is variable. In an advantageous embodiment, a fixing device arranged on the slide via a rail has a second receiving area arranged above the first receiving area, to which a second seat component can be attached to the fixing device. In other words, the rail is arranged on the carriage. This rail extends, for example, perpendicularly in its longitudinal direction to the first plane formed by the carriage and / or its translational movement. Furthermore, the fixing device is arranged on the rail. The fixing device, in turn, has a second receiving area, which is located above the first receiving area associated with the carriage. This means that the second receiving area is located above the first receiving area. The second seat component can be attached to the fixing device at this second receiving area. Since the second receiving area is located above the first receiving area, the second seat component, when attached to the fixing device, is also located above the first receiving area.This offers the advantage that the first seat component can be tested in combination with the second seat component. For example, the second seat component is attached using the fixing device and positioned adjacent to the first seat component. Alternatively, the second seat component can be attached using the fixing device and positioned at a distance from the first seat component. Furthermore, it is possible for at least one additional seat component to be arranged between the first and second seat components, above the second seat component, or below the first seat component. This additional seat component can be attached to the carriage by means of at least one additional fixing device. Alternatively, the additional seat component can be attached to the first and / or the second seat component. Examples of such additional seat components include a fan, a seat heater, a covering, cut foam, or a spacer fabric. Advantageously, the second receiving area can be aligned at different angles relative to the guide device and relative to the first receiving area. Thus, a third plane formed by the second receiving area can be arranged at different angles to the second plane formed by the first receiving area. By arranging the seat components in the receiving areas, it is possible for the second seat component to be positioned at different angles to the first seat component. For example, the third plane runs parallel or at an angle to the second plane. Thus, the second seat component can be positioned at an angle or parallel to the first seat component. Using the fixing device, the second seat component can also be positioned at an angle or parallel to the first plane formed by the translational movement of the slide. At least one additional seating component can, for example, be arranged at least essentially parallel or at an angle to the first and / or second seating component. In a further advantageous embodiment of the invention, the fixing device is adjustable along the rail attached to the slide in the second direction relative to the slide. This means that the fixing device is adjustable along the rail, which extends, for example, perpendicular to the plane formed by the slide. For example, the fixing device can be arranged at different heights above the first receiving area. This offers the advantage that, for example, the arrangement of the second seat component can be adapted to the first seat component. Thus, for example, the second seat component can be tested in combination with different first seat components of different heights. Furthermore, due to the adjustability of the fixing device, the second seat component can also be arranged at a distance from the first seat component.Furthermore, it is possible to adjust the fixing device so that the first seat component is pressed in or compressed by the second seat component, which is fixed by the fixing device. This means, for example, that the fixing device is arranged so that the second seat component causes a change in the height of the first seat component. Advantageously, the second seat component can be positioned against the first seat component by adjusting the fixing device attached to the rail in the second direction. In other words, the fixing device can be adjusted vertically along the rail relative to the carriage so that the second seat component rests against the first seat component, at least partially. This offers the advantage that, for example, a combination of a cushion as the first seat component and a cover as the second seat component can be tested. In a further advantageous embodiment of the invention, the fixing device comprises a clamping device by means of which the second seat component can be subjected to tension. This means that the second seat component is secured in the fixing device and tensioned by means of the clamping device. For example, one side of the second seat component is fixed to the second receiving area of ​​the fixing device, while the second seat component is tensioned, for example, with a ratchet or a crank. This offers the advantage that, for example, the optimal tension for the comfort of the vehicle occupant, such as of a cover as the second seat component, can be optimized. Thus, different tensions of the cover can be simulated and tested. Advantageously, a damper is provided to decelerate the translational movement of the slide induced by the spring assembly. In other words, a material is provided as a damper that decelerates the translational movement of the slide induced by the spring assembly. The damper can, for example, be located in the area of ​​the mandrel, which is arranged at least partially within the guide rail of the slide. Advantageously, the at least one spring of the spring assembly is arranged at one end of the mandrel, while the damper is arranged at the other end of the mandrel. Alternatively, the damper and the at least one spring of the spring assembly can be arranged at the same end of the mandrel. The translational movement of the slide can be influenced by the choice of damper. For example, the damper can be designed so that the slide moves only in one direction, particularly the first direction, along the mandrel located in the slide's guide rail. Alternatively, the damper can be designed, for example in combination with the spring, to allow an oscillating movement of the slide both in the first direction and in the opposite direction along the mandrel located in the guide rail. Furthermore, the invention comprises a method for testing at least one seat component for a motor vehicle using one of the embodiments of the device according to the invention described above. In this method according to the invention, the first seat component is arranged on the first receiving area of ​​the slide. Subsequently, the plunger is moved in the second direction towards the first seat component arranged on the first receiving area, and the sensor embedded in the elastomer is at least indirectly contacted with the first seat component. The slide is then moved translationally in the first direction by means of the spring device. At least during this movement, measurement data on the strain and / or pressure and / or shear within the detection device are generated by means of the sensor embedded in the elastomer. In other words, the first seat component is positioned on the slide at the first receiving area. For example, the first seat component is positioned at the receiving area such that it is fixed relative to the slide in the first direction. Subsequently, the plunger is moved towards the first seat component in the second direction. The plunger is moved towards the first seat component at least until the sensor embedded in the elastomer is in at least indirect contact with the first seat component. In particular, the plunger is moved towards the seat component until a defined limit pressure, for example in the sensing device, is measured. If, for example, the defined limit pressure is measured in the sensing device, the translational movement of the slide in the first direction can be triggered by the spring mechanism.The movement can be initiated, for example, by the pre-tensioned spring of the spring assembly. Meanwhile, individual sensors embedded in the elastomer generate measurement data regarding the strain, pressure, and / or shear occurring within the detection device. This method makes it possible, for example, to simulate and measure in the detection device the stresses caused by pressurization and simultaneous translational movement. This combined pressurization and translational movement is intended to simulate the human movement of a vehicle occupant sitting in a vehicle seat. The occupant's perception should be measured as objectively as possible using the detection device. The objective parameters of strain, pressure, and / or shear measured in the detection device enable particularly good comparability of measurements of different seat components. In an advantageous embodiment of the method, a second seat component is arranged above the first seat component on the device. Only then is the plunger moved in the second direction until the sensor embedded in the elastomer has made direct contact with the second seat component. Only then is the slide moved translationally in the first direction by means of the spring device, and at least during this movement, measurement data on strain and / or pressure and / or shear within the detection device are generated by means of the sensor embedded in the elastomer. In other words, the second seat component is secured in the fixing device and positioned above the first seat component. The second seat component is then adjusted vertically using the fixing device until it is, for example, at least substantially in contact with the first seat component. The plunger is then moved in the second direction towards both the first and second seat components. This movement continues at least until the sensor embedded in the elastomer is in direct contact with the second seat component. Specifically, the plunger moves in the second direction until the first and / or second seat component is compressed to such an extent that the limit pressure is measured in the detection device.If this limit pressure is measured in the detection device, the movement of the piston in the second direction can be stopped, for example, and the piston can be fixed in its position. The detection device generates measurement data throughout the entire movement of the piston. Once the piston has been fixed in its position, the translational movement of the slide can be triggered, for example, by means of the spring mechanism. During this translational movement of the slide, the detection device generates measurement data. This measurement data can include, for example, lateral forces occurring in the detection device due to the translational movement of the slide. Using this advantageous method according to the invention, combinations of different seating components can be tested with regard to defined parameters, which are intended to represent the human perception of comfort as objectively as possible, during simulated human movements. Further features of the invention will become apparent from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or on their own. The invention will now be explained in more detail with reference to a preferred embodiment and the drawings. The drawings show: Fig. 1, a schematic side view of a device for testing at least one seat component for a motor vehicle; Fig. 2, a schematic side view of a section of a first advantageous embodiment of the device; Fig. 3, a schematic side view of a clamping device and a second seat component; Fig. 4, a schematic sectional view of a punch with a detection device; Fig. 5, a perspective view of a section of a second advantageous embodiment of the device; Fig. 6, a top view of the section of the second advantageous embodiment of the device; and Fig. 7, a side view of a section of the second advantageous embodiment of the device. In the figures, identical or functionally equivalent elements are provided with the same reference symbols. Fig. 1 shows a schematic side view of a device 1 for testing at least one first seat component 2 for a motor vehicle. This seat component 2 can, for example, be part of the circumference of a vehicle seat. The first seat component 2 can, for example, be a foam. The device 1 for testing the first seat component 2 can, for example, serve to record objective parameters relating to loads caused by human movements, simulated by the device, on a vehicle occupant sitting in a vehicle seat. The device 1 for testing the at least one first seat component 2 comprises a frame 3, which in turn has a guide device designed as a mandrel 4. This mandrel 4 is supported, for example, at one end 5 and at its other end 6 in or on the frame 3. The mandrel 4 can be aligned at different angles relative to the frame. Furthermore, the device 1 comprises, for example, a slide 7 which has at least one guide sleeve 8. The mandrel 4 is, for example, guided through the guide sleeve 8. The slide 7 is, for example, slidably mounted along the mandrel 4 extending through the guide sleeve 8. By virtue of this mounting, the slide 7 is, for example, translationally movable along a first direction 9 along a direction of extension of the mandrel 4. Thus, the first direction 9 is defined by the direction of extension of the mandrel 4. The slide 7 is translationally movable along the mandrel 4 in the first direction 9 within a first plane. The translational movement in the first direction 9 can, for example, be triggered by a spring assembly 10. The spring assembly 10 comprises, for example, at least one spring 11 which can be pre-tensioned. The spring assembly 10 is arranged, for example, at one end 6 of the mandrel 4 and on the slide 7. At the other end 5 of the mandrel 4, for example, a damper 12 is provided, for example, in contact with the slide 7. The damper 12 is designed, for example, to decelerate a translational movement of the slide 7 in the first direction 9. The slide 7 has a first receiving area 14 in which the first seat component 2 can be received. Advantageously, the receiving area 14 is designed such that the first seat component 2 is fixed relative to the slide 7 at least in the first direction 9. For example, this fixation can be achieved by positive locking. The receiving area 14, which forms a second plane, can be oriented at different angles relative to the first plane. In the figures, the receiving area 14 is oriented at least substantially parallel to the first plane. Furthermore, the device 1 has a punch 13 movable in one direction 20. This punch 13 has a detection device 16 on its side 15 facing the first receiving area 14. The detection device 16 in turn comprises a sensor array 18 embedded in an elastomer 17, which includes individual sensors 19. Measurement data on strain and / or pressure and / or shear can be acquired by means of the detection device 16. Figure 2 shows a schematic side view of a first advantageous embodiment of the device 1. In this first advantageous embodiment of the device 1, two rails 21, visible in Figure 2, are arranged on the slide 7. For example, the device 1 can have further rails, which are not shown in Figure 2. A fixing device 22 is arranged on these rails 21. The fixing device 22 is connected to the rails in such a way that it can be arranged above and at different distances from the first receiving area 14. Thus, the fixing device 22 is adjustable along the extension direction 25 of the rails 21 relative to the first receiving area 14. The fixing device 22 has a second receiving area 23, which is designed to receive a second seat component 24. This second seat component 24 can, for example, be a seat cover of a vehicle seat. As can be seen in Fig. 2, the second receiving area 23 is arranged above the first receiving area 14. Consequently, the second seat component 24 is also arranged above the first seat component 2, which is located on the first receiving area 14. A third plane formed by the second recording area 23 can be aligned at different angles to the first plane and to the second plane formed by the first recording area 14. In the representations shown in the Fig., the second recording area 23 is arranged at least substantially parallel to the first and the second plane. For example, additional seat components not shown in the figure may be arranged above the second seat component, below the first seat component, or between the first and second seat components. The fixing device 22 further comprises a clamping device 26, which is shown separately in a schematic side view in Fig. 3. The clamping device 26 includes a fastening device 27 by means of which the second seat component 24 is attached at one end 28 to the second receiving area 23. At its other end 29, the second seat component 24 is connected to a clamping element 30. This clamping element 30 can, for example, be designed as a ratchet. Clamping of the second seat component 24 can, for example, be effected by a rotational movement 31 of the clamping element 30. Figure 4 shows a schematic sectional view of the exemplary punch 13. The punch 13 has, for example, the detection device 16 on its side 15 facing the first receiving area 14. The detection device 16 comprises the sensor assembly 18, which includes individual sensors 19, and the elastomer 17 in which the sensor assembly 18 is embedded. The sensors 19 are configured, for example, to detect strain and / or pressure and / or shear. Figure 5 shows a perspective view of a section of a second advantageous embodiment of the device 1. In this second advantageous embodiment of the device 1, the slide 7 is mounted so as to be movable translationally along the first direction 9 and against this first direction 9 via the mandrel 4 arranged in the guide sleeve 8. In the second advantageous embodiment of the device 1 shown in Figure 5, four rails 21 are arranged on the slide 7. The fixing device 22 is adjustably mounted on these rails 21 along and against the second direction 20. The second seating component 24, which is arranged on the second receiving area 23 and can be clamped by means of the clamping device 26, is also adjustable relative to the slide 7 due to the adjustability of the fixing device 22 relative to the slide 7.The fixing device 22 can be adjusted so that the second seat component 24 can be arranged adjacent to the first seat component 2. A top view of the section of the second advantageous embodiment of the device 1 is shown in Fig. 6. This view shows that in the second advantageous embodiment of the device 1, the slide 7 has two sliding guide sleeves 8, each of which receives a mandrel 4. Furthermore, this top view shows that the spring assembly 10 in this embodiment comprises two springs 11, each wound around a mandrel 4 and bearing against a guide sleeve 8 at one end. In addition, each mandrel 4 is enclosed at its end 5 by a damper 12. This top view also shows that the second seat component 24 is arranged above the first seat component 2. Fig. 7 shows a side view of a further detail of the second advantageous embodiment of the device 1. This side view shows that the second seat component 24 is arranged along the second direction 20 above the seat component 2. Thus, the detection device 16 on the side 15 of the punch 13 facing the first receiving area 14 can make direct contact with the second seat component 24 when the punch 13 moves in the second direction 20. The detection device 16 can only make indirect contact with the first seat component 2 when the punch 13 moves in the second direction 20. This is due to the arrangement of the second seat component 24 above the first seat component 2 and of the punch 13 above the second seat component 24. The device 1 shown in Fig. 1 can, for example, be used to perform an independent test of the first seat component 2. In a test procedure, or the method for testing the first seat component 2, the first seat component 2 is positioned on the first receiving area 14 of the slide 7. Furthermore, the at least one spring 11 of the spring assembly 10 is pre-tensioned. The plunger 13 is then moved in the second direction 20 towards the first seat component 2 located at the first receiving area 14. The plunger 13 moves in the second direction 20 at least until the detection device 16, located on the side 15 of the plunger 13 facing the first receiving area 14, makes contact with the first seat component 2. For example, the plunger 13 moves in the second direction 20 until a defined limit pressure is measured in the detection device 16. Alternatively, the plunger 13 can be moved in the second direction 20 until it has penetrated a defined distance into the first seat component 2 or until the plunger 13 has pressed the first seat component 2 in by a defined height.If the stamp 13 is not moved further in the second direction 20, for example because the defined limit pressure is measured in the detection device 16, then the corresponding position of the stamp 13 can be fixed. The preload of the spring 11 of the spring assembly 10 is then released, causing the slide 7 to accelerate along the first direction 9. Depending on the type of spring 11 and damper 12, the slide moves along the first direction 9 until it is decelerated by the damper 12. Alternatively, the slide 7 can, for example, move in an oscillating motion, alternating between the first direction 9 and the opposite direction. Measurement data can be recorded in the acquisition device 16 both during the movement of the piston 13 in the second direction 20 and during the translational movement of the slide 7 along the first direction 9 and / or along and opposite the first direction 9. Using the side view of the second advantageous embodiment of the device 1 shown in Fig. 7, and using the first advantageous embodiment of the device 1 shown in Fig. 2, a dependent investigation of at least two seat components can be carried out, for example. For this purpose, the first seat component 2 is arranged in the first receiving area 14 of the slide 7, as described in connection with the method for the independent investigation of the first seat component 2. The spring assembly 10 is also pre-tensioned according to the method for the independent testing of the first seat component 2. The fixing device 22 is attached to the carriage 7 by means of rails 21 arranged on the carriage 7. The second seat component 24 is fixed by means of this fixing device 22 and positioned above the first receiving area 14. The fixing device 22 is adjusted, for example, along the extension direction 25 of the rails 21 until the second seat component 24 is at least partially in contact with the first seat component 2. The piston 13 is then moved in the second direction 20 at least until the detection device 16 is in direct contact with the second seat component 24. For example, the detection device 16 is then also indirectly in contact with the first seat component 2. The piston 13 is moved in the second direction 20 until the limit pressure is measured in the detection device 16. The piston 13 is then fixed in its position. Preferably, measurement data is generated by the detection device 16 during the entire movement of the piston 13. Once the punch 13 has been fixed in its position, the pre-tensioned spring device 10 can initiate the translational movement of the slide 7 in the first direction 9. During this time, measurement data is acquired by means of the sensor 18 of the detection device 16, which is embedded in the elastomer 17. For example, the measurement data can be transferred to a computing unit and evaluated there.
