Description

INTRODUCTION

[0001] The information provided in this section serves the purpose of presenting the context of the disclosure in general. Works of the inventors currently named, insofar as they are described in this section, as well as aspects of the description that may not have been prior art at the time of filing, are neither expressly nor implicitly recognized as prior art with respect to the present disclosure.

[0002] The present disclosure relates generally to a seating arrangement for a vehicle and, in particular, to a seat base of the seating arrangement supported on a seat frame. Conventional seating arrangements include a seat base that rigidly conforms to the body shape of an average user, providing a more comfortable seating surface compared to a seat base without contouring. A conventional seat base may, for example, have a slight curve depending on the occupant's seat and thigh position. Although the contoured seating surface provides an ergonomically advantageous surface for many occupants, the seat base is typically attached to the seat frame, for example, by welding, threaded fasteners, snap-fit ​​connections, and the like. For this reason, the seat base offers no displacement movement or flexibility, thus limiting the damping experienced by an occupant when sitting on the seat base.This allows forces to be transferred directly from the seat to the occupant when the vehicle travels over bumps or uneven roads. SUMMARY

[0003] One aspect of the revelation provides a seating arrangement. The seating arrangement comprises a frame and a seat base connected to the frame. The seat base includes a rigid support structure and a spring extending between the frame and a circumferential region of the rigid support structure. In response to a user sitting on the seating arrangement, the spring between the rigid support structure and the frame flexes to allow movement of the rigid support structure relative to the frame.

[0004] Implementations of the disclosure may include one or more of the following optional features. In some implementations, the rigid support structure includes an ergonomic shape configured to conform to the contours of the user seated on the seating arrangement.

[0005] In some examples, the suspension comprises multiple springs. In other examples, the multiple springs extend between the frame and the rigid support structure along opposite sides of the rigid support structure's circumference. In still other examples, the multiple springs extend between the frame and the rigid support structure along four sides of the rigid support structure's circumference.

[0006] In some aspects, the suspension includes a flexible fabric. In some implementations, the suspension includes a flexible seal that surrounds the perimeter of the rigid support structure. In other implementations, the flexible seal is attached to a selected surface from the group consisting of: (i) an upper surface of the rigid support structure and (ii) a lower surface of the rigid support structure opposite the upper surface.

[0007] In some examples, the seat arrangement further includes a damper between a lower surface of the rigid support structure and a lower frame surface positioned beneath the seat base. The damper comprises a first magnet connected to the rigid support structure and a second magnet connected to the lower frame surface. The first and second magnets repel each other. In some aspects, the suspension allows movement of the rigid support structure relative to the frame along three axes.

[0008] Another aspect of the disclosure provides a seating arrangement. The seating arrangement comprises a frame and a seat base connected to the frame. The seat base includes a rigid support structure and a suspension extending between the frame and a circumferential region of the rigid support structure. The rigid support structure comprises an ergonomic shape configured to conform to the contours of a user seated on the seating arrangement. The suspension comprises a plurality of springs extending between the frame and the rigid support structure along opposite sides of the circumferential region of the rigid support structure. In response to a user seated on the seating arrangement, the suspension between the rigid support structure and the frame flexes to allow movement of the rigid support structure relative to the frame. This aspect may include one or more of the following optional features.

[0009] In some implementations, the springs of the majority of the springs extend between the frame and the rigid support structure along four sides of the rigid support structure's circumference. In some examples, the springs allow movement of the rigid support structure relative to the frame along three axes.

[0010] In some cases, the seat assembly further includes a damper between a lower surface of the rigid support structure and a lower frame surface positioned beneath the seat base. In other aspects, the damper comprises a first magnet connected to the rigid support structure and a second magnet connected to the lower frame surface. The first and second magnets repel each other.

[0011] Another aspect of the disclosure provides a motor vehicle. The vehicle includes a seating arrangement comprising a frame and a seat base connected to the frame. The seat base includes a rigid support structure and a suspension extending between the frame and a circumferential region of the rigid support structure. In response to a user seated on the seating arrangement, the suspension between the rigid support structure and the frame flexes to allow movement of the rigid support structure relative to the frame. This aspect may include one or more of the following optional features.

[0012] In some implementations, the rigid support structure incorporates an ergonomic shape configured to conform to the contours of the user seated on the seating arrangement. In some examples, the suspension comprises multiple springs extending between the frame and the rigid support structure along opposite sides of the rigid support structure's perimeter.

[0013] In some aspects, the suspension includes a flexible seal that surrounds the circumference of the rigid support structure. In other aspects, the flexible seal is attached to a selected surface from the group consisting of: (i) an upper surface of the rigid support structure and (ii) a lower surface of the rigid support structure opposite the upper surface.

[0017] Example configurations are now described in more detail with reference to the accompanying drawings. These example configurations are provided to ensure that this disclosure is thorough and fully conveys its scope to those skilled in the art. Specific details, such as examples of particular components, devices, and processes, are presented to facilitate a comprehensive understanding of the configurations described in this disclosure. It is obvious to those skilled in the art that specific details need not be used, that exemplary configurations can be implemented in many different forms, and that the specific details and exemplary configurations should not be interpreted as limiting the scope of this disclosure.

[0018] The terminology used herein serves only to describe certain exemplary configurations and is not to be understood as restrictive. The singular articles "a" and "the" used herein also include the plural forms unless the context clearly indicates otherwise. The terms "comprises," "comprehensive," "including / include," and "shows / show" are inclusive and therefore specify the presence of features, steps, processes, numbers, elements, and / or components, but do not exclude the presence or addition of one or more other features, numbers, steps, processes, elements, components, and / or groups thereof.The procedural steps, processes, and procedures described herein are not to be interpreted as necessarily requiring them to be carried out in the specific order explained or illustrated, unless they are expressly designated as the order of execution. Additional or alternative steps may be applied.

[0019] When an element or layer is described as being "on" or "interacting with" another element or layer, or as being "connected" or "coupled" or "attached" to the same, it may be directly on or interacting with, connected with, coupled to, or attached to the other element or layer, or there may be intervening elements or layers. However, when an element is described as being "directly on" or "directly interacting with" another element or layer, or as being "directly connected" or "directly coupled" or "attached" to the same, there must be no intervening elements or layers. Other words used to describe the relationship between elements should be interpreted similarly (e.g.,“Between” as opposed to “directly between”, “neighboring” or “adjacent” as opposed to “directly adjacent” or “directly bordering”, etc.). As used herein, the term “and / or” includes all combinations of one or more of the related listed items.

[0020] The terms first, second, third, etc., may be used here to describe different elements, components, regions, layers, and / or sections. These elements, components, regions, layers, and / or sections should not be restricted by these terms. These terms may only be used to distinguish one element, component, region, layer, or section from another. Terms such as "first," "second," and other numerical terms do not imply any sequence or order unless the context clearly indicates otherwise.Thus, a first element, a first component, a first area, a first layer or a first section discussed below could be referred to as a second element, second component, second area, second layer or second section, without deviating from the lessons of the exemplary configurations.

[0021] In this application, which includes the following definitions, the term "module" may be replaced by the term "circuit".

The term "group processor" includes a processor that, in combination with additional processors, executes code from one or more modules, either sectionally or as a whole. The term "shared memory" includes a single memory that stores code from multiple modules, either sectionally or as a whole. The term "group memory" includes memory that, in combination with additional memory, stores code from one or more modules, either sectionally or as a whole. The term "memory" may be a subset of the term "computer-readable medium."The term "computer-readable medium" excludes transitory electrical and electromagnetic signals propagating through a medium and can therefore be considered tangible, non-transient storage. Non-restrictive examples of non-transient storage include tangible, computer-readable media, including non-volatile memory, magnetic storage, and optical storage.

[0023] The devices and methods described in this application can be implemented in part or in their entirety by one or more computer programs executed by one or more processors. The computer programs comprise processor-executable instructions stored on at least one non-transient, concrete, computer-readable medium. The computer programs may also include or be based on stored data.

[0024] A software application (i.e., a software resource) can refer to computer software that causes a computer device to perform a task. In some examples, a software application may be called an "application," "app," or "program." Examples of applications include, but are not limited to, system diagnostic applications, system administration applications, system maintenance applications, word processing applications, spreadsheet applications, messaging applications, media streaming applications, social networking applications, and gaming applications.

[0025] Non-transient memory can refer to physical devices used for the temporary or permanent storage of programs (e.g., sequences of instructions) or data (e.g., program status information) for use by a computer device. Non-transient memory can be volatile and / or non-volatile addressable semiconductor memory. Examples of non-volatile memory include, but are not limited to, flash memory and read-only memory (ROM) / programmable read-only memory (PROM) / erasable programmable read-only memory (EPROM) / electronically erasable programmable read-only memory (EEPROM) (e.g., typically used for firmware, such as boot programs).Examples of volatile storage include, but are not limited to, random access memory (RAM), dynamic random access memory (DRAM), static random access memory (SRAM), phase change memory (PCM), and floppy disks or tapes.

[0026] These computer programs (also known as programs, software, software applications, or code) comprise machine instructions for a programmable processor and may be implemented in a procedural and / or object-oriented high-level language and / or in assembly / machine language. The terms "machine-readable medium" and "computer-readable medium" as used herein refer to any computer program product, non-transient computer-readable medium, device, and / or apparatus (e.g., magnetic disks, optical disks, memory, programmable logic devices (PLDs)) used to provide machine instructions and / or data to a programmable processor, including a machine-readable medium that receives machine instructions as a machine-readable signal. The term "machine-readable signal" refers to any signal used to provide machine instructions and / or data to a programmable processor.

[0027] Various implementations of the systems and techniques described herein may be realized in digital electronic and / or optical circuits, integrated circuits, specially designed ASICs (application-specific integrated circuits), computer hardware, firmware, software, and / or combinations thereof.

[0028] The processes and logic flows described in this description can be executed by one or more programmable processors, also known as data processing hardware, which run one or more computer programs to perform functions by responding to input data and producing outputs. The processes and logic flows can also be executed by specialized logic circuits, such as an FPGA (Field Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit). Processors suitable for executing a computer program include, for example, both general-purpose and specialized microprocessors, as well as one or more processors in all types of digital computers. Generally, a processor receives instructions and data from read-only memory, random-access memory, or both.The essential elements of a computer are a processor for executing instructions and one or more memory devices for storing instructions and data. Generally, a computer also includes one or more mass storage devices for storing data, such as magnetic, magneto-optical, or optical disks, or is operationally coupled to them to receive data from or transmit data to them, or both. However, a computer does not necessarily have to have such devices. Computer-readable media suitable for storing computer program instructions and data include all forms of non-volatile memory, media, and storage devices, such as semiconductor memory devices (e.g., EPROM, EEPROM, and flash memory devices), magnetic disks (e.g., internal hard disks or removable disks), magneto-optical disks, and CD-ROM and DVD-ROM disks.The processor and memory can be supplemented by special logic circuits or integrated into them.

[0029] To enable interaction with a user, one or more aspects of the revelation can be implemented on a computer that has a display device, such as a CRT (cathode ray tube), LCD (liquid crystal display) monitor, or touchscreen, for showing information to the user, and optionally a keyboard and pointing device, such as a mouse or trackball, with which the user can input information into the computer. Other types of devices can also be used to enable interaction with the user; for example, the user can receive any form of sensory feedback, such as visual, auditory, or tactile feedback, and user input can be received in any form, including acoustic, verbal, or tactile input.Additionally, a computer can interact with a user by sending and receiving documents to and from a device used by the user, for example, by sending web pages to a web browser on a user's client device in response to requests received from the web browser.

[0030] With reference to Fig. 1 and Fig. 2. A vehicle 10 comprises an interior cabin 14 that accommodates one or more seating arrangements 12 at corresponding seating positions within the interior cabin 14 of the vehicle 10, for example, a driver's seat 12, 12a at a driver's seat position and a passenger seat 12, 12b at a passenger seat position. It can be understood that the seating arrangement 12 can be positioned at any passenger position in a vehicle without departing from the context of this disclosure.

[0031] With reference to Fig. 3 The seat assembly 12 comprises a support structure or frame 16 configured to support the upholstery or padding of the seat assembly 12. The frame 16 and the upholstery may be covered with a covering, such as fabric, vinyl, leather, or another suitable material, to provide a Class A surface for the seat assembly 12. Furthermore, the frame 16 may include one or more floor fixings or rails 18 on a lower section of the frame 16 configured to secure the seat assembly 12 within the interior cabin 14 of the vehicle 10, such as to the floor of the interior cabin 14. The frame 16 also includes a rear frame section 20 configured to support the backrest of the seat assembly 12 and a lower frame section 22 configured to support the seat cushion of the seat assembly 12.In the illustrated example, the lower frame section 22 is generally positioned above the floor supports 18 of the frame 16 and defines a lower cavity or seat cushion receiving section 24 of the frame 16. That is, the lower frame section 22 can generally provide a perimeter frame structure, with the lower cavity 24 extending between or within the lower frame section 22. Thus, the lower cavity 24 is enclosed by the lower frame section 22 and is configured to receive a seat base or cushion assembly 26 of the seating arrangement 12. Fig. 4) As discussed below, the seat base 26 may include padding, and the seat base 26 and the lower frame section 22 may be covered with the seat assembly 12.

[0032] With reference to Fig. 4. The seat base 26 comprises a rigid support structure 28 that is connected to or supported by the lower frame section 22 of the frame 16. Although not shown, the rigid support structure 28 of the seat base 26 may support and / or encase cushions or upholstery material. The rigid support structure 28 may be formed from any suitable material that provides rigid support to the user when seated in the seating arrangement 12, such as wood, composite material, metal, or the like. Furthermore, the rigid support structure 28 comprises an ergonomic shape or contour, such as a shape based on an average user of the seating arrangement 12.By incorporating a contoured shape into the rigid support structure 28, even when the rigid support structure 28 is ultimately covered with foam, leather, fabric, and / or other materials, the contoured shape contributes to a more comfortable and tailored seating experience for the user, particularly when the user sits on the seating arrangement 12 for extended periods. As further explained below, the rigid support structure 28 is supported on the lower frame section 22 of the frame 16 by a flexible suspension 36 that extends between a circumferential or edge region 30 of the support structure 28 and the lower frame section 22.

[0033] The seat base 26 comprises a first or upper surface 32 and a second or lower surface 34 opposite the upper surface 32. The upper surface 32 can face the interior 14 of the vehicle 10 and includes the contoured shape of the rigid support structure 28, such that the upper surface 32 is configured to accommodate the user seated on the seat assembly 12. The lower surface 34 can face away from the interior cabin 14, for example, towards the floor of the interior cabin 14.

[0034] The suspension 36 extends between the circumferential edge region 30 of the support structure 28 and the lower frame section 22, and flexes between the support structure 28 and the lower frame section 22 to allow movement of the seat base 26 and the user relative to the frame 16. When the vehicle is traveling on the road, the suspension 36 can, for example, flex or deflect to allow movement of the support structure 28 relative to the frame 16 and to at least partially dampen or absorb forces, thereby preventing the forces from acting on the user through the seat assembly 12.

[0035] This means that by attaching the seat base 26 to the frame 16 with the suspension 36, the seat base 26 is able to provide the user with flex while seated on the seat assembly 12. This occupant flex provides the user with an additional degree of suspension, which offers greater comfort, especially when the vehicle 10 travels over bumpy and / or uneven roads. The suspension 36 can, for example, allow movement of the seat base 26 along three axes of movement relative to the frame 16. In other words, and as described in Fig. As shown in Figure 4, the suspension 36 allows movement of the seat base 26 in the X direction (e.g., along a longitudinal axis of the vehicle), in the Y direction (e.g., along a transverse axis of the vehicle), and in the Z direction (along a vertical axis). When the suspension 36 is combined with the contoured shape of the rigid support structure 28, the user is provided with a seat base 26 that not only adapts to the user's contours but also provides enhanced suspension to increase the level of user comfort, especially when the vehicle 10 is in motion. Furthermore, the suspension 36 can respond to the user seated on the seat assembly 12 and provide a more comfortable feel on the seat base 26, even when the vehicle 10 is stationary.

[0036] In some examples, the suspension 36 comprises a plurality of springs 38 extending between at least one section of the circumferential edge region 30 of the rigid support structure 28 and the lower frame section 22. For example, the springs 38 between the rigid support structure 28 and the lower frame section 22 can extend along opposite sides of the rigid support structure 28, such as along a first side 30a of the circumferential edge region 30 and along an opposite second side 30b of the circumferential edge region 30. Optionally, the springs 38 between the rigid support structure 28 and the lower frame section 22 can extend substantially around the circumferential edge region 30, for example along the first side 30a, the second side 30b, a third or front side 30c, and a fourth or rear side 30d.

[0037] A plurality of mounting holes 40 can be formed around the circumferential edge region 30 of the support structure 28 to allow the attachment of the plurality of springs 38. In one configuration, the springs 38 are coil springs that are movable between a relaxed state and an extended or extended state. Thus, each spring 38 comprises a first end 42 that is attached to the circumferential edge region 30 of the rigid support structure 28, such as in a corresponding mounting hole 40, and a second end 44 that is attached to the lower frame section 22 in a corresponding mounting hole (not shown). Thus, the seat base 26 cannot directly contact any section of the frame 16, but rather the seat base 26 is connected to the frame 16 via the plurality of springs 38. This provides the seat base 26 with three-dimensional movement relative to the frame 16.This means that as the support structure 28 and the attached padding move with the user relative to the lower frame section 22, the springs 38 extend and contract to support the user and absorb forces, thereby limiting the transmission of forces from the seat assembly 12 to the user. Furthermore, the suspension 36 can push the support structure 28 into a centered or preset position to keep the user in a desired seating position when traveling on uneven or bumpy roads.

[0038] Optionally, the suspension 36 can include a flexible fabric extending between the support structure 28 and the lower frame section 22. For example, and with reference to Fig. 5. The suspension 36 can comprise a flexible fabric 46 attached to the circumferential edge region 30 of the rigid support structure 28 and enclosing the seat base 26. The flexible fabric 46 comprises a seat edge 48 attached to the seat base 26 and a frame edge 50 attached to the lower frame section 22. The flexible fabric 46 can be attached to the seat base 26 and the lower frame section 22 by any suitable means, such as adhesive, screws, and the like. Furthermore, the type of flexible fabric 46 used for the suspension 36 can be a woven fabric, a metal mesh, a rubber sheet, or another suitable material to support the user seated on the seating arrangement 12 and to allow three-dimensional movement of the seat base 26 relative to the frame 16.As the support structure 28 and the attached padding move with the user relative to the lower frame section 22, the flexible fabric 46 can bend and / or stretch to support the user and absorb forces. In this way, the forces experienced by the lower frame section 22 when the vehicle 10 travels over rough or uneven road surfaces are absorbed by the suspension 36 and not transmitted to the user.

[0039] Optionally, the suspension 36 can include a flexible seal or a rubberized material that surrounds the circumferential edge region 30 of the rigid support structure 28. For example, and with reference to Fig. 6. The suspension 36 can comprise a flexible seal 52, which is attached to the circumferential edge region 30 of the rigid support structure 28 and encloses the seat base 26. The flexible seal 52 comprises a sealing seat edge 54, which is attached to the seat base 26, and a sealing frame edge 56, which is attached to the lower frame section 22. The sealing seat edge 54 can be attached to at least one upper edge section of a circumferential edge 58 of the support structure 28 (i.e., at a connection point between the circumferential edge 58 and the upper surface 32 of the support structure 28) and one lower edge section of the circumferential edge 58 (i.e., at a connection point between the circumferential edge 58 and the lower surface 34 of the support structure 28). The flexible seal 52 can be attached to the seat base 26 and the lower frame section 22 by any suitable means, such as adhesive, screws, and the like.Furthermore, the flexible seal 52 used for the suspension 36 can be a rubber or silicone seal, a foam material, or another suitable flexible and durable material to support the user seated on the seat assembly 12 and to allow three-dimensional movement of the seat base 26 relative to the frame 16. Thus, as the support structure and the attached padding move with the user relative to the lower frame section 22, the flexible seal 52 can flex and / or stretch to support the user and absorb forces. In this way, the forces experienced by the lower frame section 22 when the vehicle 10 travels over rough or uneven road surfaces are absorbed by the suspension 36 and not transmitted to the user.

[0040] With further reference to Fig. 6 The seat arrangement 12 includes one or more dampers 62 which provide a damping effect to resist movement of the seat base 26 when the user is seated on the seat arrangement 12. Although Fig.Figure 6, which is shown as containing the flexible seal 52 of the suspension 36 and the one or more dampers 62, the seat assembly 12 can include one or more of the suspension components discussed herein and / or one or more dampers 62. That is, the dampers 62 can be attached to the seat assembly 12 in conjunction with the suspension 36, including one or more of the plurality of springs 38, the flexible fabric 46, and the flexible seal 52. As further explained below, the one or more dampers 62 are arranged between the rigid support structure 28 and a surface or structure below the seat base 26 to resist movement of the seat base 26 at least in the vertical Z-direction.The dampers 62 can provide less rigid support than the frame 16 of the seating assembly 12 in order to at least partially dampen or absorb forces and thereby prevent them from being perceived by the user. One or more lashing elements or straps 64 can extend between the seat base 26 and the frame 16 to restrict the movement of the seat base 26 within a range of motion. That is, the fastening elements 64 can prevent evasive movement of the seat base 26 and ensure smooth three-dimensional movement.

[0041] In the illustrated example, each damper 62 comprises a first magnet 66 located on the lower surface 34 of the rigid support structure 28 and a corresponding second magnet 68 on a lower frame surface 70 located below the seat base 26, such as at or near the base supports 18 of the frame 16. The first magnet 66 and the second magnet 68 repel each other to provide the damping force between the lower frame surface 70 and the support structure 28. For example, the first magnet 66 may have a north pole opposite the north pole of the second magnet 68. The fasteners 64 generally hold the first magnet 66 positioned above the second magnet 68 to maintain the mutual repulsive action of the first magnet 66 and the second magnet 68.While the suspension 36 absorbs the three-dimensional movement of the seat base 26, the damper 62 can at least partially prevent movement along the vertical Z-direction and reduce the transmission of vibrations to the user through the seat assembly 12. In some examples, the magnets of the damper 62 can be electromagnets, allowing the damper to be selectively activated, for example, based on user input or the determination that the vehicle is traveling over a particularly bumpy section of road.

[0042] By connecting the seat base 26 to the frame 16 via the suspension 36, in combination with the rigid support structure 28 of the seat base 26, which has a shape specifically contoured to the user, the seat arrangement 12 provides the user with ergonomic comfort and support. The configurations described in this disclosure can be individually tailored to different seating arrangements in different vehicles and adapted to different passenger positions in different vehicles based on manufacturer preference. The differences in the configurations may include, but are not limited to, the exact placement and orientation of the suspension, the stiffness of the suspension, whether dampers are incorporated, and the exact shape of the contoured seat base.

[0043] Several implementations have been described. It is understood, however, that various modifications can be made without deviating from the spirit and scope of the disclosure. Accordingly, other embodiments also fall within the scope of the following claims.

[0044] The foregoing description is provided for illustrative and descriptive purposes only. It makes no claim to be exhaustive or to limit the disclosure. Individual elements or features of a particular configuration are generally not restricted to that particular configuration but are optionally interchangeable and may be used in a selected configuration even if not specifically shown or described. They may also be modified in many ways.
