Description

Technical Field

[0001] This invention relates to a seat, specifically a vehicle seat. Background Technology

[0002] Vehicle seat testing is well-known in existing technology. For example, test dummies (also known as crash test dummies) are used to test vehicle seats. In the test, the test dummies are used to simulate the effects of an accident on the human body. In addition, according to UN Regulation 14 (Uniform Regulation on the Approval of Seatbelt Anchorages in Vehicles, EU Notification of 12 13 2019, L324 / 14-L324 / 46, [2019 / 2141]; hereinafter referred to as UN Regulation 14; English version: UNECE: UN-R14 / 09, Suppl.3, 2 July 2024), static testing is performed using a traction device to simulate the effects on the seatbelt anchorage point.

[0003] In addition, existing technologies, such as US2001 / 0011810A1, EP1362737A1, WO02 / 066285A1, US11091120B2 and US2023 / 365098A1, disclose seats, such as vehicle seats or bus seats, which can be adjusted between different positions, specifically between different seat positions, reclining positions, bed positions, etc.

[0004] At this point, this type of seat must be strong enough to absorb the force of the seat belt and ensure that there is no excessive forward or downward displacement of the pelvis (the pelvis "diving" under the seat belt) caused by an accident. Summary of the Invention

[0005] question The problem to be solved by the present invention is to provide a seat of the type described at the beginning, which in particular ensures the reduction or even avoidance of anterior pelvic displacement and subsidence caused by accidents.

[0006] Solution According to the present invention, this problem is solved by a seat having the features of claim 1.

[0007] Advantageous improvements that can be used alone or in combination with each other are the subject of the dependent claims.

[0008] The seat according to the invention is configured as a vehicle seat, for example for one of vehicle classes M1 / M1G / M2 / M3 or N1 / N2 / N3 as exemplified in Annex 6 or point 5.4.2.1 of UN Regulation 14, and includes at least a seat portion, a backrest connected to the seat portion, and a seat belt including a seat belt strap for restraining an occupant seated in the seat or a dummy arranged in the seat, wherein the seat belt strap extends between two lower seat belt anchor points and an upper seat belt anchor point, and wherein, during the application of increased force on the seat, the two lower seat belt anchor points are configured to be movable forward and / or backward in a forward manner.

[0009] Specifically, the two lower seatbelt anchor points are designed to move forward and / or backward from the predetermined starting position of the lower effective seatbelt anchor (also known as the lower effective seatbelt anchor position) to a predetermined control area (specifically, the control position) during the application of increased force (specifically, the force induced by control). In other words, in response to the application of force (specifically, the test force), the lower seatbelt anchor points can move out of their effective position (i.e., the lower effective seatbelt anchor position).

[0010] By controlling the movement of the seatbelt system, the load acting on the occupant's body can be reduced. Furthermore, the seatbelt can be tested under experimental loads. This controlled movement can absorb and redistribute impact energy, thereby reducing the peak force transmitted to the occupant and improving occupant safety in the event of a collision.

[0011] The additional force application specifically refers to the force application caused by control (also known as the force application caused by testing), where the test load is applied to the seat, specifically the seat belt, for example, by tension. The force exerted on the seat, specifically by means of a traction device, is higher than the seat's normal operating load. The additional force application is carried out in accordance with UN Regulation 14, points 6 "Testing" to 7 "Inspection during and after static testing of seat belt anchorage," pp. L324 / 23 to L324 / 28, point 7.4, the contents of which are incorporated herein by reference.

[0012] The lower safety belt anchorage point specifically refers to point 5.4.2.5 on pages L324 / 20 to L324 / 21, “Location of Safety Belt Anchorage,” of UN Regulation No. 14 and Annex 3. Figures 1 to 2 The lower effective seat belt anchors are specified as L1 and L2. The lower seat belt anchor points can be fixed to the vehicle structure, seat structure, or other parts of the vehicle, or they can be distributed across these different attachment points.

[0013] Here, each lower seat belt anchor point can be set and configured to secure the ends of two adjacent seat belts for two seats arranged adjacent to each other.

[0014] The increased force specifically refers to the test load, such as tension, acting on the seat belt.

[0015] The forward movement of the lower seatbelt anchor point is specifically understood as a combination of forward pivoting motion and forward and / or backward linear motion, or simply pivoting motion or simply forward and / or backward linear motion.

[0016] This invention is based on the following considerations: In accordance with Article 5.1.3 of UN Regulation 14, the lower effective seatbelt anchors L1 and L2 are located within the angle ranges α1 and α2 defined by the respective seat variant, and these angle ranges comply with Article 5.1.5 of UN Regulation 14, and they must not deviate from these angle ranges in all conventional use positions. During testing, specifically in inspection tests simulating accidents (collisions), the location of the lower seatbelt anchor points is not restricted in accordance with Article 14 of UN Regulation 14.

[0017] The advantage of this invention lies in applying real occupant loads to the seat and seatbelt using a dummy (also known as a test dummy or crash test dummy). The propulsive movement of the lower seatbelt anchor point, specifically forward and / or backward, ensures that pelvic thrust and / or dummy / crash test dummy sinking do not occur as a result of the test. Therefore, it ensures that the seatbelt is fully tested to accommodate the applied test loads.

[0018] During normal force application, such as when the seat is in the use position, the lower seatbelt anchor point is positioned and held stationary. Only under increased force application caused by testing will the lower seatbelt anchor point move forward.

[0019] Furthermore, during the application of increased force, the lower anchor point of the seatbelt can move downwards. This allows for greater tension in the seatbelt. Consequently, the seatbelt can fit more tightly against the dummy, ensuring its safety and preventing it from "slipping" off.

[0020] For example, during the application of increased force, the lower seatbelt anchor point can be mechanically moved forward in a forward-moving manner. Specifically, during the application of increased force, the lower seatbelt anchor point can be moved forward by means of a pyrotechnic unit.

[0021] The pyrotechnic unit may include, for example, a triggering device and an airbag, wherein activation of the triggering device activates a mechanism that moves the two seatbelt anchor points forward and / or downward.

[0022] Alternatively, during the application of increased force, the lower seatbelt anchor points can be moved forward via at least one preload element. For example, when increased force (specifically due to tension) is applied to the seatbelt strap, the preload element can be activated by means of the seatbelt strap, whereby the preload element can engage with the seatbelt anchor points, thereby moving the latter forward. Alternatively, the preload element can be directly coupled to the lower seatbelt anchor points so that they can be moved forward directly after activation by the seatbelt strap. For example, a separate preload element can be provided for each lower seatbelt anchor point.

[0023] For example, the corresponding lower seatbelt anchor point may be moved forward and / or downward from the legally defined area during the application of increased force, specifically by pivoting, for example, by more than 0.5° and / or more than 2 mm, respectively, relative to the predetermined starting position of the seat, before the application of the test load. The starting position of the corresponding lower seatbelt anchor point here corresponds to the position of the effective lower seatbelt anchor as defined in section 5.4.2 and efface of UN Regulation No. 14, specifically the angles α1 and α2 listed in the Annex Table on page L324 / 43 and further defined in section 5.1.5. The contents of UN Regulation No. 14 according to sections 5.1.5 and 5.4.2.1 to 5.4.2.4 of the Table on page L324 / 43 are incorporated herein by reference. Here, these angles α1, α2 vary depending on the vehicle type and / or seat type, and therefore may vary, as illustrated by example in sections 5.4.2.1 to 5.4.2.4 of UN Regulation No. 14.

[0024] Specifically, the lower seatbelt anchor points are configured such that they are movable in a forward manner only during force applied by inspection or testing (specifically, increased force applied under predetermined test loads), as illustrated in the example in point 6.4 of UN Regulation 14, “Special test requirements for seatbelt anchorages.”

[0025] For example, the two lower seatbelt anchor points can be configured to move forward simultaneously or synchronously. Alternatively, they can also move forward differentially via event control.

[0026] In summary, and in other words, the present invention provides a seat in which the lower effective seat belt anchorage moves via a mechanism during the application of increased forces caused by a collision (accident) or test, such that: 1) Moving forward and / or backward in the direction of travel, deviating from the predetermined area, specifically the predetermined legal area; 2) From the predetermined area, specifically the predetermined legal area, move forward and / or backward in the direction of travel, while simultaneously moving downward; or 3) Pivot forward and / or downward from the designated area (specifically, the designated legal area) in the direction of travel; In order to additionally achieve seat belt tension and / or improve seat belt wiring.

[0027] For example, this movement can be achieved using the following different mechanisms: a) The mechanism can be moved directly by means of a pyrotechnic unit or by means of a deflection device. b) The device is propelled by means of pyrotechnic elements, such as airbags used during flight. c) Release by means of preloaded elements, for example, release by seatbelt force during a collision (accident), and / or d) By means of direct mechanisms, such as tensioning mechanisms, spring mechanisms, etc., for example, by releasing the force of the seat belt in a collision (accident). Attached Figure Description

[0028] The present invention will now be described in more detail with reference to the preferred embodiments shown in the accompanying drawings. However, the present invention is not limited to these embodiments. In the accompanying drawings: Figure 1 A schematic diagram of a seat is shown, specifically a vehicle seat with longitudinal adjustment. Figure 2 A schematic diagram of a seat according to the invention, with two lower seatbelt anchor points and an upper seatbelt anchor point, is shown. The lower seatbelt anchor points are movable in a forward-moving manner. Figure 3 The diagram shows the basis for the two lower safety belt anchor points. Figure 2 The diagram shows the seat, with the lower seatbelt anchor point movable in a forward-moving manner.

[0029] All corresponding parts in the diagrams have the same label. Detailed Implementation

[0030] The following text will describe the vehicle seat 100 using three spatial directions that are perpendicular to each other (e.g., Figure 1 (Illustrative illustration, representing prior art). For a vehicle seat 100 installed in a vehicle, the longitudinal direction x extends substantially horizontally and is preferably parallel to the longitudinal direction of the vehicle, which corresponds to the vehicle's usual direction of travel. The lateral direction y is perpendicular to the longitudinal direction x, also extends horizontally in the vehicle, and is parallel to the lateral direction of the vehicle. The vertical direction z is perpendicular to the longitudinal direction x and perpendicular to the lateral direction y. For a vehicle seat 100 installed in a vehicle, the vertical direction z is preferably parallel to the vehicle's vertical axis.

[0031] The positional and directional specifications (e.g., front, rear, up, down) used refer to the line of sight of an occupant seated in the normal seating position on the vehicle seat 100. The vehicle seat 100 is mounted on the vehicle with its upright backrest 104 positioned in a suitable position for passenger transport and generally facing the direction of travel. The vehicle seat 100 specifically refers to seat 200, such as a single seat or part of a bench seat, as defined in point 2.6 of United Nations Regulation No. 14, which is incorporated herein by reference. However, the vehicle seat 100 may also be mounted or moved in different orientations, for example, as a rear-facing seat 200. Unless otherwise stated, the vehicle seat 100 may be designed to be mirror-symmetrical, for example, with respect to a plane perpendicular to the lateral direction y. Benches or narrow vehicle seats 100 or other suitable vehicle seats 100 may also be provided as vehicle seats 100.

[0032] The backrest 104 can be pivotally mounted on the seat portion 102 of the vehicle seat 100. For this purpose, the vehicle seat 100 may optionally include accessories 106, specifically adjustment accessories, rotation accessories, latching accessories, or folding accessories.

[0033] The positional and orientation specifications (e.g., radial, axial, and circumferential) used are related to the axis of rotation 108 of fitting 106. Radial refers to being perpendicular to the axis of rotation 108. Axial refers to being along or parallel to the axis of rotation 108.

[0034] The vehicle seat 100 optionally includes a longitudinal adjustment device 110. The longitudinal adjustment device 110 includes, for example, a guide rail arrangement 112 having a first guide rail element 114 and a second guide rail element 116. The first guide rail element 114 is adjustable relative to the second guide rail element 116 in the longitudinal direction x. The first guide rail element 114 is fixed to the seat portion 102. The second guide rail element 116 is fixed to a structural element of the vehicle, such as the vehicle floor.

[0035] For clarity, the first guide rail element 114 will be referred to as the upper guide rail 114 in the following text. The upper guide rail 114 (also referred to as the running rail or slide rail) is assigned to the vehicle seat 100 and is used to support the vehicle seat 100. The second guide rail element 116 will be referred to as the lower guide rail 116 in the following text. The lower guide rail 116 is fixedly connected to, for example, the floor of a vehicle.

[0036] Vehicle seat 100 can be configured as, for example, a conventional seat 200 with seat belt 204 (e.g.) Figure 2 (as shown) or a seat with an integrated seatbelt 202.

[0037] Figure 2Seat 200 is shown, specifically configured as vehicle seat 100. Seat 200 can be a vehicle seat with an integrated seat belt 202. Alternatively, seat 200 can also be equipped with a conventional seat belt 204, which is fastened to the vehicle structure or other vehicle components, as shown by the dashed line.

[0038] Seat 200 can be, for example, a vehicle seat 100 conforming to one of vehicle classes M1 / M1G / M2 / M3 or N1 / N2 / N3, as defined in Annex 6 or point 5.4.2.1 of UN Regulation No. 14. Seat 200 can be, in particular, a bus seat, a van seat, a truck seat, etc.

[0039] Similar to vehicle seat 100, seat 200 includes at least seat portion 102 and backrest 104 connected to seat portion 102.

[0040] Seat 200 is a seat with an integrated seat belt 202, including a seat belt 204 integrated on seat 200. Seat belt 204 includes at least one seat belt strap 206 for restraining an occupant (not shown in detail) sitting on seat 200 or a dummy (not shown in detail) arranged on seat 200.

[0041] The seatbelt strap 206 extends between the two lower seatbelt anchor points 208 and the upper seatbelt anchor point 210. The seatbelt strap 206 may extend within the seat 200 (shown in dashed lines) and partially extend onto the seat 200 (shown in solid lines), and may deflect at the two seatbelt anchor points 208, 210, and may be securely held at the remaining lower seatbelt anchor point 208 by means of a seatbelt tongue 212 releasably engaged with the seatbelt buckle 214.

[0042] The upper seatbelt anchor point 210 is integrated, for example, into the seat 200. Alternatively, the upper seatbelt anchor point 210 can also be fixed to the side wall of the vehicle structure, specifically the B-pillar or C-pillar, or other suitable locations, such as the roof, rear bulkhead, etc. The lower seatbelt anchor point 208 is located on the side of the seat 200, on the seat structure of the seat portion 102. Alternatively, the lower seatbelt anchor point 208 can be fixed to the vehicle structure or other components of the vehicle.

[0043] Figure 3 The side of seat 200 is shown, as well as a first permissible attachment area 400 according to UN Regulation 14, which is used to determine the position of the lower effective anchorages L1, L2 of the lower seat belt anchorage point 208 on the corresponding side of the seat, and a second permissible attachment area 402, which is used to determine the position of the upper effective anchorage B of the upper seat belt anchorage 210.

[0044] Specifically, during the application of an increased force (specifically, a test-induced force), the two lower seatbelt anchor points 208 can be moved forward and / or backward from the initial position 304 of the predetermined lower effective seatbelt anchor 36 (also known as the lower effective seatbelt anchor position) in a forward-moving manner into a predetermined control area 406, specifically to any control position 408 within the control area 406. In other words, in response to the application of a force (specifically, a test force), the lower seatbelt anchor points 208 can be moved beyond their effective position (=lower effective seatbelt anchor position=lower effective seatbelt anchor 306).

[0045] Therefore, the controlled movement of the seatbelt 204 (also known as the seatbelt system) can reduce the load acting on the occupant's body. Furthermore, the seatbelt 204 can be subjected to test loads. This controlled movement can absorb and redistribute impact energy, thereby reducing the peak force transmitted to the occupant and improving occupant safety in a collision.

[0046] Here, further permissible attachment areas 404 can be pre-defined for the additional upper harness anchorage point 210. The definitions of these permissible attachment areas 400, 402, and 404 for the attachment areas of the effective harness anchorages L1, L2, and B are described on pages L324 / 35 to L324 / 36 of Annex 3 to UN Regulation 14, the contents of which are incorporated herein by reference.

[0047] According to UN Regulation No. 14, point 5.1.3 and Annex 3 Figure 1 These lower effective seatbelt anchors L1, L2 for the corresponding seat variants are located within the defined angle ranges α1, α2, depending on the corresponding vehicle type and / or seat type (Annex 3 to UN Regulation No. 14). Figure 1 (and the tables on pages L324 / 43 of the appendix), for example, within a range of 20° to 80° of the predetermined first attachment area 400 located in the usual use position of seat 200.

[0048] The upper effective seat belt anchorage B may be located within the predetermined permissible attachment areas 404 and 402 of the seat 200 in its usual use position, as per Annex 3 of UN Regulation No. 14. Figure 1 As shown.

[0049] Seat 200 has reference points R for determining these permissible attachment areas 400, 402, 404.

[0050] The present invention provides that, during inspection and testing, while an increased force is applied to the seat 200, the corresponding side underbelly anchor point 208 is movable in a forward manner according to the direction of arrows 300, 302, specifically moving forward and / or backward into a predetermined control area 406.

[0051] For example, the two lower seat belt anchor points 208 are movable in a forward manner under the action of an increased force, specifically under the action of a test-induced force (also known as an inspection-induced force), wherein they move forward and / or backward under a test load (e.g., a tensile force) acting on the seat 200, specifically on the seat belt 204.

[0052] The increased force is described in accordance with the provisions of point 7.4 on pages L324 / 23 to L324 / 28 of United Nations Regulation 14, "Tests" to "Inspections during and after static tests of seat belt anchorages", which is incorporated herein by reference.

[0053] The lower seat belt anchor point 208 moves in a forward manner (e.g.) Figure 2 (As shown) Specifically, it should be understood as a combination of pivoting motion forward according to arrow 300 and linear motion downward according to arrow 302, or simply pivoting motion or simply linear motion forward and / or downward.

[0054] The present invention is based on the following considerations: In accordance with Article 14, point 5.1.3 of the United Nations Regulation, for each seat variant, the lower effective seat belt anchors L1, L2 are located within the angle range α1, α2 defined in accordance with Article 14, point 5.1.5 of the United Nations Regulation and the table in the Annex on page L324 / 43, and they must not deviate from this angle range in all commonly used positions.

[0055] During the testing, specifically the inspection test simulating an accident (collision), there were no prior restrictions on the positions of the lower effective seat belt anchors L1 and L2, in accordance with Article 14 of the United Nations Regulations.

[0056] The advantage of this invention lies in the fact that a real human load is applied to the seat 200 and seat belt 204 by means of a dummy (also known as a test dummy or inspection dummy (not shown)), wherein the forward movement of the lower seat belt anchor point 208 to a predetermined control area 406 ensures that forward pelvic movement and / or dummy sinking occur as a result of the test. This ensures that the seat belt 204 can be fully tested under the applied test load.

[0057] During normal force application, such as when seat 200 is in the use position, the lower seat belt anchor point 208 is arranged and held in a fixed manner. The lower seat belt anchor point 208 will only move forward in the event of increased force application caused by testing or release through one of the aforementioned mechanisms (e.g., pyrotechnic unit 216, preload element, tensioning mechanism, spring mechanism, etc.).

[0058] Furthermore, during the application of increased force, the lower seatbelt anchor point 208 can move downwards along arrow 302. This causes the seatbelt 204 to be tightened to a more pronounced degree. Consequently, the seatbelt 204 can fit more tightly against and secure the dummy, preventing the dummy from "slipping" off the seatbelt 204.

[0059] For example, during the application of increased force, the lower seatbelt anchor point 208 can be mechanically moved downward and / or forward in a forward manner. Specifically, during the application of increased force, the lower seatbelt anchor point 208 can be moved forward by means of the pyrotechnic unit 216.

[0060] The pyrotechnic unit 216 may include, for example, a triggering device 216.1 and an airbag 216.2. By means of the activation of the triggering device 216.1, the airbag 216.2 activates a mechanism 216.3, which causes the two lower seatbelt anchor points 208 to move forward and / or downward in accordance with arrows 300, 302.

[0061] Alternatively, during the application of increased force, the lower seatbelt anchor point 208 can be moved forward and / or downward in a forward manner via at least one preload element 218. For example, the preload element 218 can be activated by means of the seatbelt strap 206 when an increased force (specifically due to tension) is applied to the seatbelt strap 206.

[0062] The preload element 218 may engage, for example, with the lower seatbelt anchor point 208 to allow it to move forward. Alternatively, the preload element 218 may be directly coupled to the lower seatbelt anchor point 208 to allow the latter (lower seatbelt anchor point) to move forward directly when activated by the seatbelt strap 206. For example, a preload element 218 may be provided individually for each lower seatbelt anchor point 208.

[0063] For example, each lower seatbelt anchor point 208 is movable in a forward manner, specifically pivotable, moving forward and / or downward into a predetermined control area 406 compared to a predetermined starting position (specifically, the starting position of the lower effective seatbelt anchors L1 and L2 under no test load), and in each case the movement angle is greater than 1°.

[0064] In other words, the starting position of the corresponding lower safety belt anchor point 208 corresponds to the position of the lower effective safety belt anchor L1, L2 as defined in accordance with clause 5.4.2 and below of UN Regulation 14.

[0065] Alternatively, the lower seatbelt anchor point 208 can be configured to move forward and / or downward from the legally defined area into a predetermined control area 406 during the application of increased force, for example, moving more than 2 mm or 0.5 mm relative to the predetermined starting position in each case.

[0066] Specifically, the lower seat belt anchor point 208 is configured to move forward and / or downward only during force applied by the test or inspection (specifically, during the application of increased force under a predetermined test load).

[0067] For example, the two lower seatbelt anchor points 208 can be configured to move forward and / or downward simultaneously or synchronously by means of at least one pyrotechnic unit 216 and / or by means of at least one preload element 218. Alternatively, they can move forward and / or downward in a differentiated, event-driven manner.

[0068] Here, each lower seat belt anchor point 208 can be set and configured to secure the ends of two adjacent seat belts 204 of two adjacently arranged seats 200.
