Description

Technical Field

[0001] The invention relates to a decoupling module for two components which are releasably connected to one another, and to a vehicle seat having such a decoupling module. Background Art

[0002] DE 10 2009 033 721 B4 and DE 10 2011 014 869 A1 are known fastening devices for releasably fixing an element on a vehicle component. Summary of the invention

[0003] Technical issues

[0004] The problem to be solved by the present invention is to improve a decoupling module of the type mentioned above, in particular to enable decoupling also under load, and to provide a corresponding vehicle seat having an improved decoupling module.

[0005] Solution

[0006] According to the invention, the first problem is solved by a decoupling module having the features of claim 1. According to the invention, the second problem is solved by a vehicle seat having the features of claim 15 .

[0007] Advantageous embodiments which can be implemented individually or in combination with one another are the subject matter of the dependent claims.

[0008] The decoupling module according to the invention for two releasably interconnected components comprises at least a module housing, in particular with an external first coupling interface, in particular for coupling to one of the components, and a hollow space, a locking unit, which is on the one hand axially movably mounted in the module housing and, in an initial state, in particular in a locking position or a blocking position for locking the connection between the two components, at least partially protrudes from the module housing, in particular for releasably locking or coupling the two components relative to each other, and a drive unit, which is on the other hand arranged in a positionally fixed manner in the module housing, wherein the locking unit and the drive unit are designed to interact with each other so that when the drive unit is triggered or ignited, the locking unit can be subjected to a pressure shock propagating in the hollow space or suddenly and directly subjected to this pressure shock and move into the module housing. The locking unit can be axially displaced along a linear axis and moved linearly into the module housing. In other words: the decoupling module is designed as a linear locking release device, in particular a linear bolt release device or a linear lever release device, with the locking unit and the drive unit interacting with each other.

[0009] The propagating pressure surge or the overall pressure build-up can be generated, for example, by the gas or gas mixture of the drive unit being introduced into the hollow space. The hollow space is also referred to as the gas space. Since the pressure surge acts directly on the locking unit, a particularly compact decoupling module with high operating forces and high operating pressures can be achieved.

[0010] In addition, the module housing, the locking unit and the drive unit can be arranged coaxially with respect to each other, for example. Preferably, the module housing, the locking unit and the drive unit can be oriented and arranged coaxially with respect to their longitudinal axis. In particular, the module housing has a beaker-shaped hollow space, in which the locking unit and the drive unit are arranged coaxially with respect to each other. In addition, the module housing, the locking unit and the drive unit can each, for example, at least partially overlap and be arranged coaxially with respect to each other. The coaxial arrangement of the components of the decoupling module allows for simple manufacture of the decoupling module as well as a simple, modular and, in particular, compact structure.

[0011] The drive unit can be designed, for example, as a pyrotechnic device. The drive unit can in particular be supported on the module housing on the one hand and on the locking unit via its front end on the other hand.

[0012] The decoupling module, in particular a module housing, for example a module cover, can additionally have a second (for example external) coupling interface.

[0013] The first coupling interface of the module housing can be designed as an external thread. The second coupling interface of the module housing can be designed, for example, as a nut, in particular a hexagonal profile or a hexagonal nut. In this way, the decoupling module can be easily fastened to one of the two components to be connected without using tools in the case of only one coupling interface or using a wrench in the case of two coupling interfaces.

[0014] For example, one axial end of the drive unit can be designed as a module cover, which is connected to the module housing by a form fit and / or force fit in the assembled state of the decoupling module. For example, the module cover can be assembled to the module housing by crimping, screwing or the like.

[0015] For example, the module housing and the drive unit can be connected to each other so that in the assembled state they are sealed off from the outside in a gas-tight manner. The module housing can be sealed off from the outside in a gas-tight manner in particular so that when the drive unit is triggered, the locking unit is at least temporarily held in the retracted position. Alternatively, the locking unit can be designed to be lockable in the retracted position.

[0016] In addition, the module cover can be arranged to partially overlap the module housing. For example, the module housing and the module cover can be telescopically assembled one inside and one outside. For example, the module cover can at least partially slide over the outer wall of the module housing. Alternatively, the outer wall of the module housing can partially slide over the module cover. Such a design allows variable adjustment of the module housing of the decoupling module, thereby achieving different module sizes and module dimensions.

[0017] The locking unit can, for example, comprise a locking part and a pressure-effecting part, which, when the drive unit is triggered or ignited, can be subjected to a pressure shock, so that the locking unit moves into the module housing under acceleration and the two parts are decoupled from each other. The location at which the force acts on the locking unit can be designed in a variety of ways, in particular in relation to the geometric design, orientation and arrangement of the locking unit relative to the drive unit and can be influenced by these parameters.

[0018] The pressure effect part can be designed, for example, as a cylindrical hollow cavity or a beaker-shaped hollow cavity with at least one recess or with at least one gas channel. The at least one recess or the at least one gas channel can be designed, for example, as a gas passage, a through-flow opening, an overflow opening, an overflow channel, etc. For example, the pressure effect part can include a plurality of recesses or a plurality of gas channels that are symmetrically distributed (particularly symmetrically distributed on the pressure effect part).

[0019] The at least one recess or the at least one gas channel extends in an axial longitudinal direction and in a transverse direction continuing perpendicularly to the axial longitudinal direction. For example, the extension in the axial longitudinal direction is greater than the extension in the transverse direction. In this way, when the drive unit is triggered, the propagation pressure impact of the gas guided into the hollow space is optimized. In particular, the pressure can act on a larger surface area.

[0020] The locking part can be designed, for example, as an axle end, a rod, a pin or other suitable locking element. In the connected state of the two components, the locking unit (in particular the locking element) can be mounted in a pre-tensioned manner by means of a force storage unit (in particular a spring element, in particular a pre-tensioning spring) for the locked connection of the two components. The pre-tensioning spring is particularly designed to pre-tension the locking unit in the initial state, in particular in the locked state (also referred to as the locked position) or the blocked state (also referred to as the blocked position). In particular, the force storage unit and the sealing ring are configured so that in particular the sealing force of the sealing ring is greater than the pre-tensioning force of the force storage unit. In this way, when the drive unit is triggered, the decoupling module is sufficiently sealed against pressure shocks and is locked sufficiently firmly in the initial state so that the locking unit remains in its position, in particular in its blocked position or locked position.

[0021] The energy storage device can carry or support itself on the one hand on the pressure-effective part and on the other hand on the module cover, on the module housing or directly on a drive unit connected to the module housing in a fixed manner.

[0022] The module housing can additionally have an opening, for example on the housing base, for an axial end of the locking unit, through which the axial end projects at least partially from the module housing in the connected state in order to connect or hold the two components to one another by locking.

[0023] The vehicle seat according to the invention comprises the above-described decoupling module.

[0024] In summary, in other words, the invention provides an axisymmetric decoupling module which has, on the one hand, a first coupling interface of a module housing designed as a thread with an opening for a locking unit designed as a pin or an axle end, and, on the other hand, a second coupling interface designed, for example, as a hexagon or a nut.

[0025] By means of such a decoupling module having at least one of the coupling interfaces, the decoupling module can be easily screwed onto one of the components. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] exist Figure 1 The vehicle seat 100 schematically shown in the figure will be described below based on three mutually perpendicular spatial directions. When the vehicle seat 100 is 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 normal driving direction of the vehicle. The transverse direction y extending perpendicularly to the longitudinal direction x is similarly oriented horizontally in the vehicle and extends parallel to the transverse direction of the vehicle. The vertical direction z extends perpendicularly to the longitudinal direction x and perpendicularly to the transverse direction y. When the vehicle seat 100 is installed in a vehicle, the vertical direction z preferably extends parallel to the longitudinal axis of the vehicle.

[0042] The positional terms and directional terms used, such as front, rear, upper and lower, relate to the direction of sight of an occupant sitting in a normal sitting position on the vehicle seat 100, which is installed in a vehicle in a use position suitable for transporting passengers, with an upright backrest 104, and oriented in the direction of travel in a conventional manner. However, the vehicle seat 100 can also be installed or moved to other orientations, such as transverse to the direction of travel. Unless otherwise specified, the vehicle seat 100 is configured to be mirror-symmetrical to a plane extending perpendicular to the transverse direction y.

[0043] The backrest 104 can be arranged pivotably on the seat part 102 of the vehicle seat 100. To this end, the vehicle seat 100 can optionally include a fitting 106, in particular an adjustment fitting, a swivel fitting, a latch fitting or a flip fitting.

[0044] Positional and directional terms used, such as radial, axial, and circumferential, are relative to the rotational axis 108 of the assembly 106. Radial refers to perpendicular to the rotational axis 108. Axial refers to the direction of or parallel to the rotational axis 108.

[0045] The vehicle seat 100 may optionally include a longitudinal adjustment device 110. The longitudinal adjustment device 110 comprises, for example, a rail arrangement 112 with a first rail element 114 and a second rail element 116. The first rail element 114 is adjustable in the longitudinal direction x relative to the second rail element 116. The first rail element 114 is fastened to the seat part 102. The second rail element 116 is fastened to a structural element of the vehicle, for example a vehicle floor.

[0046] For greater clarity, the first rail element 14 is referred to in the following description as a top rail 114. This top rail 114 (also referred to as a continuation rail or a slide rail) is assigned to the vehicle seat 100 and is configured to carry the vehicle seat 100. The second rail element 116 is referred to in the following as a bottom rail 116. The bottom rail 116 is, for example, fixedly connected to the floor of the vehicle.

[0047] A decoupling module 200 may be provided in order to allow, for example, immediate decoupling of components of the vehicle seat 100 , in particular components of the longitudinal adjustment device 110 , in the event of a crash.

[0048] Figure 2 An exploded view of a decoupling module 200 according to the invention is shown in a first exemplary embodiment.

[0049] The decoupling module 200 includes at least one module housing 202. The module housing 202 is designed as a hollow body. The module housing 202 has a hollow space 204. The hollow space 204 is in particular hollow cylindrical or beaker-shaped. The module housing 202 can be modularly designed. The module housing 202 can include a module body 202.1 and a module cover 202.2. The module housing 202 additionally includes a first coupling interface 202.3.

[0050] The first coupling interface 202.3 is designed as an external interface for coupling to one of the two components, which are releasably lockable to each other or locked to each other by means of the decoupling module 200. The first coupling interface 202.3 is designed, for example, as an external thread. The first coupling interface 202.3 is designed, for example, as an external thread on the outside of the first front end 202.4. The decoupling module 200 can thus be easily screwed into or onto one of the two components.

[0051] The decoupling module 200 additionally comprises a locking unit 206 and a drive unit 208. The locking unit 206 is on the one hand axially movably mounted in the module housing 202. In an initial state, the locking unit 206 at least partially protrudes from the module housing 202, in particular in order to releasably lock or couple the two components to each other, such as Figure 4 shown.

[0052] The drive unit 208 is, on the other hand, arranged in a stationary manner in the module housing 202 .

[0053] The locking unit 206 and the drive unit 208 are designed to interact with each other so that when the drive unit 208 is triggered or ignited, the locking unit 206 can be affected by the pressure shock propagating or accumulating in the hollow space 204 or suddenly and directly affected by the pressure shock and move into the module housing 202.

[0054] The locking unit 206 is axially movable along the linear axis 210 and linearly moves into the module housing 202 after the drive unit 208 is triggered. In other words: the decoupling module 200 is designed to utilize the locking unit 206 and the drive unit 208 that interact with each other as a linear locking release device, in particular a linear bolt release device or a linear rod release device.

[0055] The drive unit 208 can be designed as a pyrotechnic device, such as a gas generator with a pyrotechnic initiator. The drive unit 208 can be supported on the module housing 202, in particular on the module cover 202.2, and on the locking unit 206 via its front end.

[0056] The module housing 202 can be additionally designed with a second coupling interface 202.5. For example, the second coupling interface 202.5 is an external interface, for example, designed as a nut or a hexagonal interface.

[0057] The module cover 202.2 can be arranged, for example, on a second front end 202.6 of the module body 202.1 opposite the first front end 202.4 and can be connected to the module body 202.1 by a form fit and / or force fit engagement in the assembled state of the decoupling module 200. For example, the module cover 202.2 can be assembled to the module body 202.1 by crimping, screwing or the like.

[0058] The module cover 202.2 may have a bracket 202.9 for the drive unit 208, which bracket 202.9 extends in the direction of the module body 202.1.

[0059] Furthermore, the module housing 202 and the drive unit 208 can be connected to each other so that in the assembled state they are sealed off from the outside in a gas-tight manner. For example, at least one seal 212 can be provided. The seal 212 comprises, for example, two first sealing rings 212.1, which are arranged between the locking unit 206 and the module housing 202. For example, the seal 212 can additionally or alternatively be designed as a second sealing ring 212.2, which is arranged outside the drive unit 208 and closes the module cover 202.2 from the outside.

[0060] The module housing 202 can be sealed from the outside in a gas-tight manner, in particular by means of sealing rings 212.1 and 212.2, so that the locking unit 206 is at least temporarily held in the retracted position when the drive unit 208 is triggered. Alternatively, the locking unit 206 can be designed to be lockable in the retracted position.

[0061] The locking unit 206 may, for example, include a locking portion 206.1 and a pressure effect portion 206.2, which, when the drive unit 208 is triggered or ignited, may be subjected to a pressure shock, so that the locking unit 206 moves into the module housing 202 under acceleration and the two components are decoupled from each other. The position where the force acts on the locking unit 206 (particularly the pressure effect portion 206.2) may be designed differently according to the geometric design, direction and arrangement of the locking unit 206 relative to the drive unit 208 and is affected by these parameters.

[0062] The pressure effect part 206.2 can be designed, for example, as a cylindrical cavity or a beaker-shaped cavity with at least one recess 206.3. The at least one recess 206.3 can be designed, for example, as a gas passage 206.4. Alternatively, the recess 206.3 can be designed as a through-flow opening, an overflow opening, etc. For example, the pressure effect part 206.2 can include a plurality of recesses 206.3 distributed symmetrically.

[0063] The locking part 206.1 can be designed, for example, as an axle end 206.5. Alternatively, the locking part 206.1 can be designed as a rod, a pin or another suitable locking element. In the connected state of the two components, therefore in the initial state, the locking part 206.1 can be mounted in a pre-tensioned manner by means of a force storage 214, in particular a spring element, in particular a helical spring or a pre-tensioned spring, for the locked connection of the two components.

[0064] The module housing 202 can additionally have an opening 202.8, for example in a housing base 202.7 for an axial end 206.5 of the locking unit 206 (in particular for a bolt-shaped or pin-shaped axial end 206.5), through which, in the connected state, the axial end 206.5 protrudes at least partially from the module housing 202 so as to connect or fix the two components to each other by locking.

[0065] Figure 3 A perspective view and a partial cross-sectional view of a decoupling module 200 according to a first exemplary embodiment are shown in an assembled state.

[0066] The module cover 202.2 may be arranged to partially overlap the module body 202.1. For example, the module body 202.1 and the module cover 202.2 may be telescopically assembled one inside and one outside. For example, the outer wall of the module body 202.1 may partially slide over the module cover 202.2.

[0067] The bracket 202.9 of the module cover 202.2 is designed internally to correspond to the external shape and / or external dimensions of the drive unit 208. Externally, the bracket 202.9 is designed so that the power storage device 214 can support itself thereon. For example, the bracket 202.9 has at least one shoulder 202.10 externally. Internally, the bracket 202.9 can have a groove 202.11 for the second sealing ring 212.2. In addition, the module cover 202.2 can have a fastening flange 202.12, which is arranged in a fastening groove 202.13 of the module body 202.1 using a form fit and / or force fit engagement.

[0068] Upon ignition of the drive unit 208, the latter generates a pressure surge or overall pressure by means of the gas 216 or gas mixture which is guided into the hollow space 204. The hollow space 204 is also referred to as the gas space. The gas 216 acts on the pressure-effective part 206.2 of the locking unit 206. The fact that the pressure surge acts directly on the locking unit 206 allows a particularly compact decoupling module 200 with high operating forces and with high operating pressures.

[0069] Due to the pressure shock acting thereon, the locking unit 206 moves linearly into the module housing 202, resulting in a linear bolt release or a linear lever release.

[0070] For compact design, the module housing 202, the locking unit 206 and the drive unit 208 may be arranged coaxially with each other. Preferably, the module housing 202, the locking unit 206 and the drive unit 208 may be oriented and arranged coaxially with each other with respect to their longitudinal axis and the linear axis 210.

[0071] Furthermore, the module housing 202 , the locking unit 206 , and the driving unit 208 may, for example, each be arranged to at least partially overlap and be coaxial with each other.

[0072] Figure 4 A perspective view of a decoupling module 200 according to a first exemplary embodiment is shown in an assembled state.

[0073] The force storage device 214 is supported on the one hand on the shoulder 202 . 10 of the module cover 202 . 2 and on the other hand on the front end of the pressure-effective part 206 . 2 of the locking unit 206 .

[0074] The fastening flange 202.12 of the module cover 202.2 can be additionally equipped with an anti-rotation member 202.14. The anti-rotation member 202.14 can be formed, for example, by at least one radially protruding rib and a corresponding groove on the inner side of the module body 202.1. In the installed state, the rib is engaged in the groove in a non-rotatable manner. This can assist in screwing the decoupling module 200 into one of the components (particularly the internal thread) via the first coupling interface 202.3 (particularly the external thread) by means of a tool (particularly a hexagonal or nut element) engaged in the second coupling interface 202.5.

[0075] Figure 5 A perspective view of the module cover 202 . 2 with the drive unit 208 is shown, which are preassembled together.

[0076] At its front end, the module cover 202.2 has an attachment opening 202.15 for the drive unit 208. An attachment unit 208.1 for the attachment of electrical wires and / or transmission wires protrudes into the attachment opening 202.15. The attachment unit 208.1 is arranged in the attachment opening 202.15 which is freely accessible from the outside.

[0077] The anti-rotation member 202.14 may have a plurality of ribs symmetrically arranged below the fastening flange 202.12.

[0078] Figure 6 A perspective view of the locking unit 206 is shown.

[0079] The locking unit 206 has a locking portion 206.1 with an axial end 206.5 for lockingly connecting the two components to each other (not shown) and a pressure effect portion 206.2 with a recess 206.3 designed as a gas passage 206.4.

[0080] The pressure effect portion 206.2 has a beaker-shaped design and comprises a number of alternately arranged separation webs 206.6 and recesses 206.3.

[0081] Figure 7 An exploded view of a decoupling module 300 according to the invention is shown in a second exemplary embodiment.

[0082] The decoupling module 300 differs from the decoupling module 200 only in the form of the locking unit 306 and the module housing 302. All other structural features and functions of the decoupling module 300 are similar to those of the decoupling module 200 described above.

[0083] Instead of the decoupling module 200 having the recess 206.3 designed as the gas passage 206.4, the decoupling module 300 has a gas passage 306.4 as the recess 306.3. For example, the gas passage 306.4 may be arranged on the outside of the inwardly protruding bracket 302.9 of the module housing 302. Alternatively or additionally, the gas passage 306.4 may be formed on the inside of the hollow cylindrical pressure effect portion 306.2 of the locking unit 306.

[0084] The locking portion 306.1 protrudes from the pressure effect portion 306.2 in the direction of the module body 302.1.

[0085] The decoupling module 300 is closed in a gas-tight manner from the outside by means of a seal 312 designed as a sealing ring 312 . 1 .

[0086] The drive unit 308 is similarly arranged and held in a positionally fixed manner in the module cover 302 . 2 , in particular by means of a positive and / or force-fitting connection.

[0087] Figure 8 shows an exploded view of a decoupling module according to the invention in a third exemplary embodiment, and Fig. 9 Shown in assembled state according to Figure 8 Decoupling module 400.

[0088] The decoupling module 400 differs from the decoupling module 200 or 300 only in the structure of the locking unit 306. All other structural features and functions of the decoupling module 400 are similar to those of the decoupling module 200 or 300 described above.

[0089] The locking unit 406 of the decoupling module 400 has a multi-piece design. The locking unit 406 comprises a separate locking part 406.1, which is designed as a separate pin. The pressure effect part 406.2 is also designed as a separate one. The pressure effect part 406.2 is designed as an inner hollow cylinder or an inner cylindrical shell.

[0090] The pin-shaped locking portion 406.1 can be fitted into the pressure effect portion 406.2. The shape and / or size of the locking portion 406.1 is such that when fitted into the pressure effect portion 406.2, it protrudes through the opening 406.3 in the direction of the module body 402.1 of the module housing 402, extends through the housing opening 402.3 flush with the opening 406.3, and protrudes outward from the module body 402.1.

[0091] The module body 402.1 is a hollow cylinder and forms an outer part of the module housing 402. The module body 402.1 may be closed by a module cover 402.2 on a side opposite to the housing opening 402.3.

[0092] Two seals 412 designed as sealing rings 412.1 are provided for sealing the module housing 402. By means of the seals 412 designed as sealing rings 412.1, the decoupling module 400 is closed from the outside in a gas-tight manner.

[0093] The drive unit 408 is similarly arranged and held in the module cover 402 . 2 in a positionally fixed manner, in particular by means of a form-fitting and / or force-fitting connection.

[0094] In the connected state of the two components, the locking part 406.1 can be mounted in a pre-tensioned manner in the module body 402.1 by means of a force storage device 414, in particular a spring element, in particular a helical spring, for the locking connection of the two components, such as Fig.11 and Fig.12 shown.

[0095] Furthermore, the decoupling module 400 may, for example, include an elongated attachment element 416. The attachment element 416 is designed as an interface or adapter for attaching a pipeline or cable to the drive unit 408. The attachment element 416 is a cylindrical element, in particular made of a flexible material. The attachment element 416 (also referred to as an elongated diverter ring) has a longitudinal gap 416.1. The longitudinal gap 416.1 is particularly used for compensation of tolerances.

[0096] Fig. 9 Show according to Figure 8A perspective view of a decoupling module 400 in the assembled state with an outer module cover 402.2 and an attachment element 416 protruding from the latter, and with an outer module body 402.1 and a pin-shaped locking portion 406.1 of a locking unit 406 protruding from the latter.

[0097] Fig.10 406. The multi-piece locking unit 406 comprises a pin-shaped locking portion 406.1 and a cylindrical pressure effect portion 406.2.
