Description

Technical Field

[0001] This invention relates to a vehicle seat for motor vehicles (especially autonomous motor vehicles). Furthermore, the invention includes motor vehicles (e.g., autonomous motor vehicles) having such a vehicle seat. Background Technology

[0002] The term "autonomous motor vehicle" (and sometimes "autonomous land vehicle") refers to passenger cars or other motor vehicles that can drive, park, and control without the influence of a human driver (highly automated or autonomous driving). The term "robotic vehicle" is also used if the driver does not require any manual control at all. The driver's seat may remain empty; there may be no steering wheel, brake pedal, or accelerator pedal. The term "autonomous motor vehicle" also includes trucks, agricultural tractors, and military vehicles that are not affected by a driver or have no driver at all.

[0003] The term "car seat" is used to refer to the vehicle seat installed in the passenger compartment of a motor vehicle for the purpose of occupants. Depending on the type of vehicle used, the distinction between driver and passenger seats, and the level of equipment, the vehicle seats installed in a motor vehicle can, in principle, differ from one another.

[0004] Most passenger vehicle models feature a pair of individual seats in the front. The driver's seat is typically located on the side facing oncoming traffic, with steering and control instruments facing that side. Additional features, such as seat heating, air conditioning, and ventilation, are often provided for the driver's seat and, in some cases, the front seats. In top-of-the-line vehicles, screens can be mounted on the rearward side of the front seatbacks, allowing rear passengers to watch television, videos, etc. Models with even more comfortable features include armrests.

[0005] However, due to the transition to highly automated or autonomous driving, traditional interior space design for passengers is increasingly seen as limiting. In particular, the driver may be able to adopt alternative seating positions. Summary of the Invention

[0006] Therefore, the object of this invention is to find a method that can help in this regard.

[0007] The object of the present invention is achieved by a motor vehicle, particularly an autonomous driving motor vehicle, having at least one vehicle seat configured to be positioned in a selected location among a plurality of locations in the passenger compartment of the motor vehicle.

[0008] Therefore, vehicle seats can be positioned in alternative locations within the passenger compartment, and known vehicle seats are configured to be adjustable from a single position. This allows the driver and other passengers to select alternative seating positions in a surprisingly simple way.

[0009] According to one embodiment, the vehicle seat has a connection means for connecting the vehicle seat components to motor vehicle components at a selected location. Therefore, the vehicle seat can be easily connected to motor vehicle components (such as, for example, the vehicle's onboard network) at a selected location to provide electrical operating power for operating the vehicle seat components.

[0010] According to another embodiment, the vehicle seat component is a seat ventilation device and the motor vehicle component is an air supply device having at least one air outlet at each of a plurality of locations. Thus, the seat ventilation device can be supplied with air, and the air guiding system is at least partially disposed in the area under the floor of the motor vehicle.

[0011] According to another embodiment, a sealing device for closing the corresponding air outlet is associated with each air outlet. Therefore, unused air outlets, that is, air outlets not connected to the inlet nozzles of the seat ventilation system, can be closed.

[0012] According to another embodiment, the seat ventilation device has a bayonet closure for connection to one of the air outlets. This allows for tool-less connection between the air outlet and the inlet nozzle.

[0013] According to another embodiment, the vehicle seat has a heating element. Therefore, for example, a portion of the vehicle seat can be heated directly, or air can be heated for the seat ventilation system, wherein, due to the association of the heating element with the vehicle seat, air that does not need to be heated must be delivered through the vehicle's long guiding system and lose heat again.

[0014] According to another embodiment, the vehicle seat has an interface for connecting to an HMI (Human Machine Interface). Therefore, a handheld device (such as a tablet computer) can be connected to the vehicle seat, through which the vehicle's entertainment and / or infotainment components can be controlled. Additionally or alternatively, a command panel and / or joystick can also be connected via the HMI, through which the vehicle can be controlled when necessary.

[0015] According to another embodiment, the vehicle seat can be positioned at least in one of a plurality of locations to its maximum extent of extension. The vehicle seat 6 provides a full sleeping function, meaning that components of the vehicle seat (such as the seat surface and backrest) can be moved to a position where the vehicle seat provides a flat, reclining surface like a bed. In this position, the vehicle seat has its maximum extent of extension in the direction of the longitudinal axis of the motor vehicle.

[0016] According to another embodiment, the vehicle seat is configured to be adjustable for drive force compensation. For example, the vehicle seat may have an actuator that allows the horizontal tilt of the vehicle seat to be changed in four directions (upper left / lower, upper right / lower, upper front / lower, upper rear / lower). A control device controls the actuator, for example, based on the vehicle's bending radius and actual speed, to at least partially compensate for forces acting on the driver or other passengers.

[0017] The invention also includes vehicle seats for such motor vehicles, particularly vehicle seats for autonomous motor vehicles. Attached Figure Description

[0018] The invention will now be explained with reference to the accompanying drawings, in which:

[0019] Figure 1 It is a diagram of a motor vehicle.

[0020] Figure 2 This is a schematic exploded view of a vehicle seat, which can be placed... Figure 1 The interior space of the motor vehicle shown. Detailed Implementation

[0021] First refer to Figure 1 .

[0022] Motor vehicle 2 is shown, which in this embodiment is a passenger vehicle. In contrast to this embodiment, the motor vehicle could also be a truck or a bus.

[0023] Furthermore, the motor vehicle 2 in this embodiment is configured as an automated driving motor vehicle for highly automated or autonomous driving. That is, the motor vehicle 2 can also be referred to as a robotic vehicle, which meets at least Level 3 (high level of automation) of the autonomous driving classification.

[0024] The motor vehicle 2 has an interior passenger compartment 4, in which at least one vehicle seat 6 is disposed.

[0025] Now refer to another source Figure 2 Explain vehicle seat 6.

[0026] In this embodiment, the vehicle seat 6 has a seat surface 8, a backrest 10, a headrest 12, a seat sidewall 14, and a footrest 16.

[0027] In this embodiment, the positions of the seat surface 8, backrest 10, headrest 12, seat sidewall 14, and footrest 16 can be electrically changed.

[0028] In addition, the driver's seat 6 has a seat heating unit, seat air conditioning and ventilation device, as will be described in detail below.

[0029] In addition, the vehicle seat 6 can be installed at selected positions P1, P2, P3 among multiple positions P1, P2, P3 in the passenger compartment 4 of the motor vehicle 2.

[0030] Therefore, in the base area of ​​the passenger compartment 4 on the vehicle side, an air supply device 18, which is a component of the motor vehicle and has at least one air outlet 20, is provided at different locations P1, P2, and P3. For example, the air supply device 18 is provided in the area under the floor of the motor vehicle 2.

[0031] For each air outlet 20, the inlet nozzle 22 of the seat ventilation device can be connected to the vehicle seat component of the vehicle seat 6 to provide air to the seat ventilation device. For this purpose, the vehicle seat 6 is provided at selected positions P1, P2, P3 among a plurality of positions P1, P2, P3, which are defined by the corresponding positions P1, P2, P3 of the corresponding air outlet 20.

[0032] In order to securely connect the air outlet 20 to the inlet nozzle 22, in this embodiment, the inlet nozzle 22 has a bayonet closure 24 with a longitudinal groove, while the air outlet 20 has a bolt engaged in the longitudinal groove.

[0033] Since the vehicle seats 6 are arranged in selected positions P1, P2, P3, one of the air outlets 20 is connected to the inlet nozzle 22. Each of the remaining free air outlets 20, in contrast, has a closing device 26 for closing the corresponding air outlet 20. The closing device 26 can be automatically closed by creating a connection with the inlet nozzle 22, that is, the respective closing device 26 is open.

[0034] In this embodiment, the sealing device 26 is configured as a variable diaphragm. In this case, a variable diaphragm is understood to be a diaphragm with a variable opening range, wherein the opening with a fixed center point can be changed in a manner that maintains a substantially circular shape.

[0035] Furthermore, in this embodiment, the vehicle seat 6 has a heating element 28, which may be an electric heating element, such as, for example, a PTC element. The heating element 28 may be configured, for example, to directly heat the seat surface 8 and / or the backrest 10. In addition, the heating element 28 may also be configured to heat air for a seat ventilation device, which flows through an outlet 20 and an inlet nozzle 22 into the vehicle seat 6.

[0036] Furthermore, in this embodiment, the vehicle seat 6 has an interface 30 for connecting to an HMI 32 (Human Machine Interface). Thus, a handheld device (such as a tablet computer) can be connected to the vehicle seat 6, through which the entertainment and / or infotainment components of the vehicle 2 can be controlled. Additionally, a command panel and / or joystick can also be connected to the HMI 32, through which the vehicle 2 can be controlled if needed.

[0037] In this embodiment, the multiple positions P1, P2, and P3 include a front position P1, a center position P2, and a rear position P3. In this embodiment, the vehicle seat 6 is configured such that when it is positioned at the center position P2, it provides a fully reclining function, meaning that components of the vehicle seat 6 (such as the seat surface 8 and backrest 10) can be moved to a position where the vehicle seat 6 provides a flat, reclining surface in a bed-like manner. In this position, the vehicle seat 4 has its maximum extension along the longitudinal axis of the motor vehicle 2.

[0038] Finally, in this embodiment, the vehicle seat 4 has a seat control console configured to be adjustable for ride dynamics compensation. The seat control console has actuators by which the horizontal tilt of the vehicle seat 4 can be changed in four directions (upper left / lower, upper right / lower, upper front / lower, upper rear / lower). In this case, a control device (not shown) controls the actuators, for example, based on the bending radius and actual speed of the motor vehicle 2, to at least partially compensate for the forces acting on the driver or other passengers.

[0039] Furthermore, the control device can be configured to associate the actuator with the axis of motion of the corresponding seat position. For example, the vehicle seat 6 can be configured to move to a so-called panoramic position, in which, for example, the left front seat is rotated 90° to the left.

[0040] Therefore, vehicle seat 4 allows the driver and other passengers to take different alternative seating positions.
