[0009] Referring to the figures, wherein like reference numerals indicate like features throughout the several views, one example of a seating system having a seat-integrated restraint system includes a seat 14 having a backrest 22 and a seat bottom 24 extending in a seat-forward, seat-FD direction, from the backrest 22. A seat belt retractor 18 is mounted to the backrest 22, and an anchor 20 is supported by the seat bottom 24. The anchor 20 is movable rearwardly and forwardly with respect to the seat between a retracted position (i.e., a design position) and a deployed position. The seat belt webbing 32 may extend from the seat belt retractor 18 to the anchor 20.An actuator 50 / 70 is operatively coupled to the anchor 20 to move the anchor 20 between the retracted position and the extended position to present the belt webbing 32 to an occupant of the seat 14.

[0010] With reference to the Fig. 1, the vehicle 10 may be any suitable type of land vehicle, e.g., a passenger car or a commercial vehicle, such as a sedan, a coupe, a truck, an SUV, a crossover, a van, a minivan, a taxi, a bus, etc. The vehicle 10 may define a passenger compartment 12 for accommodating occupants of the vehicle 10, if any. The passenger compartment 12 may extend through the vehicle 10, e.g., from a left side of the vehicle 10 to a right side of the vehicle 10. The passenger compartment 12 includes a front end and a rear end, with the front end being in front of the rear end during forward movement of the vehicle 10.

[0011] One or more seat assemblies 14 may be supported within the passenger compartment 12, e.g., by a floor of the vehicle 10. It is contemplated that technology and the regulatory framework may evolve in the future to make the use of rotating seat assemblies safe and permissible, and in such circumstances, the seat assemblies 14 may be rotatably supported by the floor to be selectively rotated to face different directions of the passenger compartment 12, e.g., toward the front end, the rear end, the right side, the left side, etc.Only in those examples where future developments in regulations and technology enable safe and permissible use of seat assemblies 14 that are selectively rotatable to different facing positions, the safety belt assembly 16 may be an SIR in which the components of the safety belt assembly 16 are supported by the seat assembly 14. For example, the retractor 18 may be attached to the seatback 22 and the anchor 20 may be supported by the seat bottom 24 of the seat assembly 14 such that the retractor 18 and the anchor 20 rotate with the seatback 22 and the seat bottom 24 when the seat assembly 14 is selectively rotated relative to the ground to face in different directions.

[0012] The seat assembly 14 may be supported via a pivot assembly 23 or other suitable structure that allows rotation of the seat assembly 14, including conventional structures. Each seat assembly 14 includes the backrest 22 and the seat bottom 24, which can support the occupant of the seat assembly 14. For example, the occupant of the seat assembly 14 may sit on an upper surface of the seat bottom 24 and recline against the backrest 22.

[0013] The backrest 22 may include a backrest frame 26. The backrest frame 26 may include tubes, spars, etc. In particular, the backrest frame 26 may include a pair of upright frame members. The upright frame members are elongated and, in particular, are elongated in a generally upright direction (e.g., along the seat vertical axis A1) when the backrest 22 is in a generally upright position. The upright frame members are spaced apart from each other along the seat transverse axis A2. The backrest frame 26 may include one or more transverse members extending between the upright frame members.

[0014] The seat base 24 has a front end 25 and a rear end 27. The front end 25 is located in front of the rear end 27 with respect to the seat in the seat forward direction FD. The seat base 24 may include a seat base frame 28. The frame 28 may include tubes, spars, etc. In particular, the seat base frame 28 may include a pair of frame members that are elongated in the seat forward direction FD, e.g., between the front end 25 and the rear end 27 of the seat base 24. The frame members are spaced apart from each other along the seat transverse axis A2. The frame 28 may include cross members that extend between the frame members. The cross members may be elongated along the seat transverse axis A2. The frame may include a seat pan. The seat pan may be generally planar and extend from one of the frame members to the other of the frame members, e.g., along the seat transverse axis A2.The seat shell can be attached to the frame elements.

[0015] The backrest frame 26 and the seat base frame 28 may be constructed of any suitable plastic material, e.g., carbon fiber reinforced plastic (CFRP), glass fiber reinforced thermoplastic composite (organic sheet), etc. As another example, some or all of the components of the backrest frame 26 and the seat base frame 28 may be formed of a suitable metal, e.g., steel, aluminum, etc. The backrest 22 and the seat base 24 may include suitable coverings. The coverings may include a trim and padding. The trim may be fabric, leather, synthetic leather, or any other suitable material. The trim may be sewn in panels around the frames. The padding may be located between the trim and the frames. The padding may be foam or any other suitable material.

[0016] The backrest 22 is supported by the seat surface 24 at the rear end 27. The seat surface 24 extends from the backrest 22 in the seat-forward direction FD of the seat assembly 14. The rear end 27 is proximal to the backrest 22 and the front end 25 is distal to the backrest 22. The backrest 22 can be stationary or movable relative to the seat surface 24. The backrest 22 and the seat surface 24 can be adjustable in several degrees of freedom. In particular, the backrest 22 and the seat surface 24 can themselves be adjustable, in other words, can be adjustable components within the backrest 22 and / or the seat surface 24, and / or can be adjustable relative to one another.

[0017] The seat assembly 14 may include a headrest 30. The headrest 30 may be supported by the backrest 22. The headrest 30 may be located at an upper end of the backrest 22. The headrest 30 may be stationary or movable, pulled onto the backrest 22. The seatback 22 and the headrest 30 may be adjustable in multiple degrees of freedom. In particular, the backrest 22 and / or the headrest 30 may be adjustable themselves and / or may be adjustable relative to one another.

[0018] Each seat assembly 14 may include a safety belt assembly 16. As stated above, it is contemplated that future regulatory and technical developments may enable safe and permissible use of seat assemblies 14 that are selectively rotatable to different facing positions, and only in such examples may the safety belt assembly 16 be an SIR in which various components of the safety belt assembly 16, e.g., the retractor 18 and the anchor 20, are supported by the seat assembly 14.

[0019] The seat belt assembly 16 includes the retractor 18 and a webbing 32. The webbing 32 is retractably retractable from the retractor 18. The seat belt assembly 16 may include the anchor 20 attached to the webbing 32 and a buckle tongue 34 that engages a buckle 36. The webbing 32 may extend continuously from the retractor 18 to the anchor 20. The buckle tongue 34 may slide freely along the webbing 32 and divide the webbing 32 into a lap belt and a shoulder belt when it engages the buckle 36. The webbing 32 may be made of a fabric, such as polyester.

[0020] In examples where the safety belt assembly 16 is an SIR for a seat assembly 14 that is selectively rotatable to face in different directions in examples where contemplated future regulatory and technical development enables such use, as described above, the retractor 18 may be supported by the seatback 22. In other words, in such examples, the weight of the retractor 18 is borne by the seatback 22, and more particularly, the seatback frame 26. For example, the frame of the retractor 18 may be attached to the frame 26 of the seatback 22 via a weld, fastener, or other suitable structure. The retractor 18 may be supported by the seatback 22 at the upper end, as shown.

[0021] In the example where the seat belt assembly 16 is an SIR, as described above, the anchor 20 may be supported by a seat belt anchor mechanism 40, which is attached, for example, to the seat bottom frame 28. The seat belt anchor mechanism 40 may assist the occupant of the seat assembly 14 in donning the seat belt assembly 16 by moving the anchor 20 in the seat-forward direction FD from a retracted position ( Fig. 1A) into an extended position ( Fig. 1B). When the anchor 20 is in the extended position, the webbing 32 and latch plate 34 are moved away from the seatback 22 (forward relative to the seat) to a location that is more easily grasped by the occupant. Once the latch plate 34 is inserted into the buckle 36, the seat belt anchor mechanism 40 returns the anchor 20 to the retracted position. The retracted position refers to the design position of the anchor 20.

[0022] With reference to Fig. 2, an exemplary seat belt anchor mechanism 40 incorporates a rack and pinion design. The seat belt anchor mechanism 40 may include a C-shaped anchor track 44. The anchor track 44 is elongated forward and rearward of the seat and is mounted to the seat bottom frame 28. The seat belt anchor 20 is mounted to an anchor bracket 42 and movably engages the track 44 between the retracted position and the extended position. In the illustrated example, the anchor track 44 includes a rack 46 extending along a length of the track 44. A pinion 48 is disposed within the track 44 and engages the rack 46. The pinion 48 is mounted to the anchor bracket 42.

[0023] An actuator, such as an electric motor 50, may be positioned, for example, in the pinion gear 48, as shown, or in the anchor bracket 42. The electric motor 50 is operable to rotate the pinion gear 48 such that it translates along the rack gear 46 to move the anchor 20 rearwardly and forwardly relative to the seat between the retracted position and the extended position. The anchor bracket 42 may, for example, have a rectangular cross-section to mate with a slot 45 formed along the length of the C-shaped anchor rail 44. The rectangular cross-section slidably mates with the slot 45 to prevent the anchor bracket 42 from rotating relative to the rail 44 and the pinion gear 48.

[0024] The seat belt anchor mechanism 40 may include a latch 52 operable to selectively retain or lock the anchor 20 in the retracted position. The latch 52 may be an electromagnetically actuated pin mechanism including a pin 54 actuated by an electromagnet 56. The electromagnet 56 is operable to selectively extend and retract the pin 54. The electromagnet 56 may be mounted to the rail 44, with the pin 54 extendable into the path of the pinion gear 48. When the anchor 20 is in the retracted position, the electromagnet 56 may be activated to extend the pin 54, thereby locking the anchor 20 in the retracted position.

[0025] Fig. 3 illustrates another exemplary seat belt anchor mechanism 60. The seat belt anchor mechanism 60 incorporates a lead screw configuration. The seat belt anchor mechanism 60 may include a C-shaped anchor rail 64. The anchor rail 64 is elongated forward and rearward of the seat and is mounted to the seat bottom frame 28. The seat belt anchor 20 is mounted to an anchor bracket 62 and movably engages the rail 64 between the retracted position and the extended position. In the illustrated example, the anchor rail 64 receives a lead screw 66 extending along a length of the rail 64. The anchor bracket 62 includes a threaded nut portion 68 configured to threadably engage the lead screw 66.

[0026] An actuator, such as an electric motor 70, may be supported by the anchor rail 64. The electric motor 70 is operable to rotate the lead screw 66 such that the anchor bracket 62 is translated along the lead screw 66 to move the anchor 20 rearwardly and forwardly relative to the seat between the retracted position and the extended position. The seat belt anchor mechanism 60 may include a suitable locking mechanism, such as the lock 52 described above with respect to the Fig. 2 shown seat belt anchoring mechanism 40.

[0027] With reference to Fig.4, a seating system may include the seat assembly 14, the seat belt assembly 16 (including the seat belt anchor mechanism 40 / 60), as well as a computer 80, a network 86, and various sensors, including an occupancy sensor 82 and a buckle sensor 84. The vehicle 10 may include an occupancy sensor 82 configured to detect occupancy of the seat assembly 14. The occupancy sensor 82 may include visible light or infrared cameras directed toward the seat, weight sensors supported by the seat bottom 24, or other suitable structure, including those conventionally known. The occupancy sensor 82 provides data to the computer 80 indicating whether the seat assembly 14 is occupied or unoccupied.

[0028] The vehicle 10 may include a buckle sensor 84 that detects engagement of the buckle tongue 34 of the seat belt assembly 16 with the buckle 36. The buckle sensor 84 may include a switch, a contact sensor, a Hall effect sensor, or any other suitable structure for detecting engagement of the buckle tongue 34 with the buckle 36, including conventional structures. The buckle sensor 84 provides data to the computer 80 indicating whether the buckle tongue 34 is engaged or disengaged from the buckle 36.

[0029] The vehicle 10 may include a communications network 86. The communications network 86 includes hardware, such as a communications bus, to enable communication between components of the vehicle 10, e.g., the computer 80, the occupancy sensor 82, the buckle sensor 84, the anchor actuator 50 / 70, the locking mechanism 52, etc. The communications network 86 may enable wired or wireless communication between the components of the vehicle 10 in accordance with a number of communication protocols, such as a Controller Area Network (CAN), Ethernet, Wi-Fi, Local Interconnect Network (LIN), and / or other wired or wireless mechanisms. Alternatively or additionally, in cases where the computer 80 includes a plurality of devices, the communications network 86 may be used for communication between devices, which are illustrated in this disclosure as the computer 80.

[0030] The computer 80 may be a microprocessor-based computer implemented via circuits, chips, or other electronic components. The computer 80 includes a processor, memory, etc. The memory of the computer 80 may include memory for storing programming instructions executable by the processor, as well as for electronically storing data and / or databases. For example, the computer 80 may be a generic computer with a processor and memory, as described above, and / or may include an electronic control unit (ECU) or a controller for a specific function or set of functions and / or dedicated electronic circuitry, including an ASIC manufactured for a specific operation, e.g., an ASIC for processing sensor data and / or communicating the sensor data.As another example, computer 80 may be a restraint control module. In another example, computer 80 may include an FPGA (field-programmable gate array), which is an integrated circuit fabricated to be user-configurable. Typically, a hardware description language such as VHDL (very high-speed integrated circuit hardware description language) is used in electronic design automation to describe digital and mixed-signal systems, such as FPGAs and ASICs. For example, an ASIC is fabricated using VHDL programming provided prior to fabrication, whereas logical components within an FPGA may be configured based on VHDL programming stored, for example, on memory electrically connected to the FPGA circuitry.In some examples, a combination of processor(s), ASIC(s), and / or FPGA circuitry may be included in computer 80. The storage may be of any type, such as hard disk drives, solid-state drives, servers, or any volatile or non-volatile media. The storage may store the collected data sent by the sensors.

[0031] The computer 80 is programmed, ie, the memory stores instructions executable by the processor, to command the anchor actuator 50 / 70 to move the anchor 20 from the retracted position to the extended position and to move the anchor 20 from the extended position to the retracted position. The computer 80 can move the anchor 20 by transmitting a command to the anchor actuator 50 / 70 via the communications network 86. The command can specify the retracted position or the extended position.

[0032] The computer 80 may be programmed to move the anchor 20 to the extended position in response to detecting that the seat assembly 14 is occupied. The computer 80 may determine that the seat assembly 14 is occupied based on information received from the occupancy sensor 82 via the communications network 86. For example, upon receiving information from the occupancy sensor 82 indicating that the seat assembly 14 has changed from unoccupied to occupied, the computer 80 may transmit a command to the anchor actuator 50 / 70 specifying movement of the anchor 20 to the extended position. The computer 80 may transmit a command to the locking mechanism 52 to retract the locking pin 54 before commanding movement of the anchor 20.

[0033] The computer 80 may be programmed to move the anchor 20 to the retracted position in response to detecting that the buckle tongue 34 engages the buckle 36 of the seat assembly 14. The computer 80 may determine that the buckle tongue 34 is engaged with the buckle 36 based on information received from the buckle sensor 84 via the communication network 86. For example, upon receiving information from the buckle sensor 84 indicating that the buckle tongue 34 has transitioned from engaged with the buckle 36 to disengaged from the buckle 36, the computer 80 may transmit a command to the anchor actuator 50 / 70 specifying movement of the anchor 20 to the retracted position. Once the anchor 20 is moved to the retracted position, the computer 80 may transmit a command to the locking mechanism 52 to extend the locking pin 54.The computer 80 may be programmed to confirm that the anchor 20 is in the retracted position (i.e., the design position). In the event that the computer 80 determines that the anchor 20 is not in the retracted position, the computer 80 may, for example, activate audible and / or visual indicators.

[0034] Computing devices, such as computers, generally include computer-executable instructions, where the instructions may be executable by one or more computing devices, such as those listed above. Computer-executable instructions may be compiled or evaluated by computer programs created using a variety of programming languages ​​and / or technologies. In general, a processor (e.g., a microprocessor) receives instructions, e.g., from memory, a computer-readable medium, etc., and executes those instructions, thereby performing one or more processes that include one or more of the processes described in this document. Such instructions and other data may be stored and transmitted using a variety of computer-readable media.

[0035] A computer-readable medium (also called a processor-readable medium) includes any non-transitory (e.g., physical) medium that participates in providing data (e.g., instructions) that can be read by a computer (e.g., by a computer's processor). Such a medium can take many forms, including, but not limited to, non-volatile media and volatile media. Non-volatile media can include, for example, optical or magnetic disks and other persistent storage. Volatile media can include, for example, dynamic random-access memory (DRAM), which is typically main memory.
