Description
Technical Field
The present invention relates to a vehicle headrest system, which includes: a headrest body having a first support portion; at least one second support portion located on at least one of the sides of the headrest body in a stowed position and not beyond the headrest body; the connecting structure is used for connecting the second supporting part with the headrest body in a telescopic and rotatable mode, and the second supporting part can leave the folding position through the rotating motion and the telescopic motion of the connecting structure so as to meet the requirements of lateral support and backward support of the head of a passenger. The invention also relates to a method for controlling the headrest system, wherein the second support part is adjusted to the side of the headrest body by a rotational movement of the connecting structure out of the stowed position, such that it passes beyond the headrest body, and/or wherein the second support part is extended laterally at the headrest body by a telescopic movement of the connecting structure out of the stowed position.
Background
A headrest is a comfort configuration item that, in existing automotive headrests, generally provides the occupant with either a rearward support requirement or a lateral support requirement so that the occupant can support the head and neck to relieve fatigue, particularly during long distance travel. In addition, the head rest is also a device for protecting the neck of a human body and reducing relative movement of the head, and particularly, when a vehicle is in a rear-end collision, the human body falls backward due to inertia, and the performance of the head rest is directly related to the protection effect on the neck and the head of the human body.
With the continuous pursuit of riding comfort, the existing headrest can be adjusted up and down and back and forth. Most headrests on the current general market do not have a side wing adjusting function, and only have a function of adjusting the front and rear angles of the side wings configured on headrests of part of high-end vehicle types. The headrest does not satisfy the need for the passenger to lean on the side of the head or to support the head while it is being fixed, particularly when the passenger on the back is tired and needs to have a nap, when the carsickness needs to keep the head stable, and so on. Furthermore, existing headrests only provide back or side support for the head and do not address the different needs of one headrest with different orientations.
Disclosure of Invention
The invention aims at the problems and provides a vehicle headrest system, in particular to a headrest system for rear seats of double-row passenger vehicles, which can meet the requirements of leaning against the side surfaces of the heads of passengers or supporting and fixing the heads and can also realize the function of meeting different requirements in different positions.
The headrest system according to the present invention includes:
-a headrest body having a first support portion for rearward support of a passenger's head;
-at least one second support portion located in a stowed position on at least one of the two sides of the headrest body and not beyond the headrest body;
-a connecting structure, in particular a connecting rod, for connecting the second support portion telescopically and rotatably with the headrest body,
the second support part can leave the folding position through the rotating motion and the telescopic motion of the connecting structure, so that the requirements of lateral support and backward support of the head of a passenger are met.
According to a preferred aspect of the invention, the second support portion of the headrest system is adjustable to the side of the headrest body beyond the headrest body by rotational movement of the connecting structure away from the stowed position, such that a generally L-shape is formed between one second support portion and the headrest body to meet the lateral support requirements of the occupant's head. In the case of a headrest system having two second support portions, i.e. one second support portion on each side of the headrest body, the second support portions are adjusted out of the stowed position to the side of the headrest body beyond the headrest body by rotational movement of the connecting structure, so that a substantially U-shape is formed between the two second support portions and the headrest body. Furthermore, when it is desired to meet the need for rearward support of the head of a passenger, in particular a middle rear-row passenger, the at least one second support portion can be moved out of the stowed position by telescopic movement of the connecting structure, extending laterally of the headrest body, in particular in line with the headrest body, to meet the need for rearward support of the head of a passenger, in particular a middle rear-row passenger.
Naturally, the first support part of the headrest system according to the invention can also perform a rotary movement, for example, to change the support angle for the passenger's head.
According to a preferred aspect of the present invention, the headrest system further includes at least a motor capable of driving the link structure under the control of the controller, and a controller for changing the posture of the second support portion by movement of the link structure. The headrest system can thus be adjusted automatically if necessary. The motor can be arranged in particular inside the headrest body, which can be connected to the connecting structure by means of, for example, a gear, worm or hydraulic drive. The controller can refer to a suitable control device or a set of multiple control devices configured to perform at least a portion of the control tasks of the headrest system according to the invention, including, for example, an application specific integrated circuit, one or more processors, non-transitory memory having instructions stored therein. The controller is, for example, an Electronic Control Unit (ECU), which is also called a "driving computer", an "onboard computer", or the like.
Naturally, the motor can also drive the first support portion to undergo a change in phase.
According to a preferred aspect of the present invention, the headrest system further includes a control interface. The passenger can control the actuation of the connection structure through the control interface to change the position of the second support portion when necessary. For example, when the passenger wants to support the head laterally, a command can be given to the controller via the control interface, via which the motor is operated to drive the connection structure, i.e. to drive the second support part. The control interface can in particular be a touch screen arranged in the interior of the vehicle, but other input devices than a touch screen, such as microphones, knobs, keys, etc., can also be envisaged. If necessary, the control interface can also be an application on the passenger's mobile device (e.g. a mobile phone, a tablet, etc.) which can transmit the instructions entered by the passenger to the controller, in particular via a wireless connection (e.g. a bluetooth connection).
Naturally, the passenger can also change the position of the first support part in the control interface.
According to a preferred embodiment of the present invention, the controller of the headrest system is capable of automatically controlling the driving of the link structure according to image information collected by the camera in the vehicle to automatically change the posture of the second support portion. For example, the controller can analyze the head posture and/or eye movement of the occupant based on the image information, and automatically control the driving of the connection structure in conjunction with a predetermined determination condition stored in the controller to automatically change the posture of the second support portion. The headrest system according to the invention can automatically adjust the position of the headrest system without human intervention in order to meet the use requirements of passengers.
Naturally, the controller is also capable of automatically changing the bit state of the first support part in dependence on, for example, the image information.
According to a preferred aspect of the present invention, the headrest system further includes a first airbag and a second airbag, wherein the first airbag is disposed at a periphery of the second support portion to at least partially wrap the second support portion, and the second airbag is disposed at a periphery of the connecting structure to at least partially wrap the connecting structure. In particular, the headrest system further includes an inflator that is controllable by the controller according to the position of the second support portion to inflate and deflate the first and second air cells, respectively. For example, in the stowed position of the second support portion, the first and second air-bags are in a deflated condition, thereby enabling the second support portion and connecting structure to be stored in a reduced volume; in either the laterally-supported or the rearwardly-supported state of the second support portion, the first and second air bags are desirably inflated to meet the occupant's head support requirements.
The invention also relates to a method for controlling the headrest system described above, wherein the second support portion is adjusted to the side of the headrest body and beyond the headrest body by rotational movement of the connecting structure out of the stowed position, such that a substantially L-shape is formed between one second support portion and the headrest body to meet the lateral support requirements of the occupant's head; and/or the second supporting part is moved away from the folded position through the telescopic movement of the connecting structure and is laterally extended on the headrest body, and particularly the second supporting part and the headrest body are aligned to meet the requirement of backward support of the head of a passenger.
According to a preferred version of the method of the present invention, the actuation of the connection structure is controlled via an input at said control interface to change the state of the second support portion; or the drive of the connection structure can be automatically controlled according to image information acquired by a camera in the vehicle to automatically change the position of the second support part, wherein the head posture and/or eye movement of the passenger is preferably analyzed according to the image information, and the drive of the connection structure is automatically controlled in combination with a predetermined determination condition stored in the controller.
The judgment condition is stored in a non-temporary memory of the controller, the controller can compare image information collected by the camera in the vehicle with the stored judgment condition, and sends a control signal to the motor to drive the connecting structure to move under the condition that a certain condition is met, so that the state of the second supporting part is changed as required.

Detailed Description
In an exemplary embodiment, the application of the headrest system according to the present invention to a rear seat is shown. As seen in fig. 1 to 3, a headrest system according to an embodiment of the present invention includes, for example: two headrest bodies 1 corresponding to the two seats in the rear row, respectively, the headrest bodies having a first support portion for rearward support of the head of a passenger (the first support portion being the headrest body itself in this embodiment); two second support portions 2, said second support portions 2 being located, in the stowed position (see fig. 1), at the side of the headrest body and not beyond the headrest body (see the plan view of the second row of fig. 1); a connecting structure 4, such as a connecting rod 4 (see fig. 3), for connecting the second support portion 2 with the headrest body 1 in a telescopic, rotatable manner, wherein the second support portion 2 can be moved out of the stowed position by the rotational movement and the telescopic movement of the connecting rod 4 to meet the requirements of lateral support (see fig. 2) and rearward support (see fig. 3) of the head of the passenger.
According to the embodiment of the present invention, one second support portion 2 is provided on both sides for each headrest of two seats in the rear row, respectively, so that support can be given on both sides of the head of the passenger when the head of the passenger is laterally supported.
According to the present embodiment, the second support part 2 of the headrest system is adjustable to the side of the headrest body and beyond the headrest body by rotational movement of the connecting rod 4 away from the stowed position (i.e. from the position of fig. 1 to the position of fig. 2), such that in top view one second support part 2 forms a substantially L-shape with the headrest body 1 (see top view of the second row of fig. 2) to meet the lateral support requirements of the passenger's head. In the case of a headrest system having two second support portions 2, i.e. one second support portion 2 on each side of the headrest body 1, the second support portions 2 are adjusted out of the stowed position to the side of and beyond the headrest body by rotational movement of the connecting rods 4, so that the two second support portions form a substantially U-shape (not shown in the drawings) with the headrest body in plan view.
According to the present embodiment, when it is required to meet the requirement of rearward support of the head of the middle passenger in the rear row, the two second support portions 2 in the rear row can be moved away from the stowed position by the telescopic movement of the connecting rod 4, and herein, particularly, the two second support portions 2 are moved together toward each other, extending laterally of the headrest body 1 so as to be in line with the headrest body 1 (see fig. 3).
According to an embodiment of the invention, in the rear support position of fig. 3, the first airbags 3 of the two second support portions 2 and the second airbags 5 of the two connecting bars 4 can be inflated so as to improve the support comfort of said second support portions 2 and the comfort and aesthetic appearance of the connecting bars 4. Optionally, in the lateral support configuration of fig. 2, the first bladders 3 of the two second support portions 2 are inflated to enhance the comfort of lateral support. Alternatively, the first bladder 3 has different inflation states in the lateral support position and the rearward support position of the second support portion 2, respectively.
The first and second air bags 3 and 5 of the headrest system according to the embodiment of the invention may be inflated by respective or common inflators (not shown) that the controller can control according to the posture of the second support portion 2 to inflate and deflate the first and second air bags 3 and 5, respectively. For example, in fig. 1, in the stowed position of the second support portion 2, the first air bag 3 and the second air bag 5 are in a deflated state, whereby the second support portion 2 and the connecting rod 4 can be stored in a reduced volume (at this time the connecting rod 4 is received in the headrest body 1); whereas in fig. 2 and 3 the second support section 2 is in a laterally supported condition and a rearwardly supported condition respectively, the first and second air bags 3 and 5 are desirably in an inflated condition to meet the head support requirements of the occupant.
In an embodiment of the present invention, the headrest system may further include a motor and a controller (not shown in the drawings), the motor being capable of driving the connecting rod 4 under the control of the controller, and changing the posture of the second support portion 2 by the movement of the connecting rod 4. The headrest system can thus be adjusted automatically if necessary.
The motor, which can be connected to the connecting rod, for example, by means of a gear, worm gear or hydraulic drive, can be arranged, for example, inside the headrest body 1.
In an embodiment of the present invention, the headrest system may further include a control interface, so that the occupant can control the driving of the connecting rod 4 through the control interface to change the posture of the second support portion 2. For example, when the passenger wants to support the head laterally, it is possible to give an instruction to the controller via the control interface, via which the motor is operated to drive the connecting rod 4, i.e. to drive the second support part 2. The control interface may be, for example, a touch screen disposed inside the vehicle, or may be other input devices besides the touch screen, such as voice interaction devices (e.g., microphones), knobs, keys, and so forth. The control interface may also be an application on the passenger's mobile device (e.g., cell phone, tablet, etc.) that can communicate the instructions entered by the passenger to the controller via, for example, a wireless connection (e.g., bluetooth connection).
An exemplary method for controlling the headrest system according to the present invention is explained below according to the above-described embodiment, in which the method for controlling the headrest system according to the present invention is explained with an embodiment in which the driving of the connecting rod 4 is automatically controlled according to the image information collected by the in-vehicle camera to automatically change the posture of the second support portion 2, for example. However, the present invention is not limited to this embodiment, and includes a control method in which, for example, a passenger inputs at a control interface to control the driving of the connecting rod 4 to change the posture of the second support portion 2.
In the control interface, for example, a switch interface may be provided, and when the switch interface is in an on state, the headrest system according to the invention can automatically change the posture of the second support portion 2 to meet the head support demand of the occupant; when the switch interface is in the off state, the headrest system according to the present invention can change the posture of the second support portion 2 only when the occupant inputs a corresponding command.
The controller of the headrest system according to the embodiment of the present invention can also receive a signal of, for example, a pressure sensor located in the seat to determine whether or not there is a passenger in the seat, and performs image information analysis to automatically control the connecting rod 4 (i.e., the second support portion 2) when there is a passenger in the seat; or the controller can receive facial features of the driver (when the headrest system is installed in the driver's seat) and/or the passenger captured by the in-vehicle camera to automatically adjust the headrest system into a preset configuration for the particular driver and/or passenger to achieve personalized adjustments.
The controller of the headrest system according to the embodiment of the invention can also receive signals from the vehicle power system to obtain information such as whether the vehicle is in a start state, a brake state or about the vehicle speed, so that the headrest system can be adaptively adjusted into a proper position according to the information.
The headrest system according to the embodiment of the invention is brought into an operating state, for example, after the vehicle is started. In the operating state, the controller may automatically control the driving of the connecting rod 4 according to image information collected by the in-vehicle camera, and preferably may automatically control the driving of the connecting rod 4 in conjunction with predetermined determination conditions stored in the controller by analyzing the head posture and/or eye movement of the occupant according to the image information. The determination conditions are stored in a non-transitory memory of the controller, for example, and the controller can compare image information collected by the camera in the vehicle with the stored determination conditions, and send a control signal to the motor to drive the connecting rod 4 to move if a certain condition is met, so as to change the state of the second supporting portion 2 as required.
In one embodiment of the method of the present invention, when the in-vehicle camera signal received by the controller observes that the head posture of the occupant is changed to the roll or the sway state for a continuous period of time (e.g., 2 seconds) while the eye-closed/slow-moving eye-moving state is determined as the eye-movement condition (the number of blinks) when the headrest system is installed in the rear row of the vehicle, it is determined that the left/right side support is expected and/or the first support portion is expected to change the support angle, for example, the head is supported obliquely upward at an angle not perpendicular to the ground.
The shaking of the head posture means in particular that the head of the passenger swings left and right on the basis of the central axis for two rounds; the roll state of the head posture means, in particular, that the head of the passenger maintains the left or right inclined state.
The eye-closing/jogging eye activity state may be determined, for example, by:
definition e ═ max {1-d/d _ i; 0},
wherein d is the maximum vertical distance between the arcs of the upper eyelid and the lower eyelid of the eyes of the passenger,
d _ i is the diameter of the iris,
and when e is less than or equal to 0.5, judging the eye closing/slow moving eye moving state.
When the controller determines that the passenger desires left/right side support and/or desires the first support part to change the support angle, the controller drives the connecting bar 4 to rotate by the motor so that the second support part 2 protrudes laterally from the headrest body 1, and/or drives the first support part to rotate by the motor so that the support angle to the passenger's head is changed.
Further, in the method of the embodiment of the present invention, after the controller has adjusted the first supporting portion and/or the second supporting portion 2 to the supporting posture satisfying the head shake and the closed-eye/slow-eye movement state, if the controller detects again that the head posture and the eye movement condition of the passenger no longer satisfy the above determination through the in-vehicle camera, the first supporting portion and/or the second supporting portion 2 may be brought back into the initial posture by the motor. In this case, the occupant can interrupt the movement of the first support part and/or the second support part 2 back into the initial position via the control interface, so that the headrest system remains in the support position.
In another embodiment of the method of the present invention, the passenger can move the second support portion 2 (by the telescopic movement of the connecting rod) out of the stowed position through the control interface and extend laterally of the headrest body so that the second support portion is in line with the headrest body to meet the need for rearward support of the passenger's head. In this case, particularly in the case of three persons riding in the rear row, the passenger located in the middle can have a rearward support of the head.
In an embodiment of the invention, the controller of the headrest system may automatically control the second support portion 2 by means of an in-vehicle camera upon observing a passenger in the middle of the rear row for a continuous period of time (e.g. 2 seconds). Here, it is possible, for example, for two second support parts 2 to be moved together towards one another to form a further, rear-supporting headrest.
In a preferred embodiment of the method of the invention, the controller is able to inflate the second airbag 5 surrounding the connecting rod 4 and/or the first airbag 3 surrounding the second support part 2 by means of an inflator when controlling the first and second support parts 2 out of the stowed position for a more comfortable support.
It should be understood that the above-described embodiments of the present invention are intended to be illustrative, but not limiting, of exemplary implementations of headrest systems according to the present invention. Rather, in addition to the embodiments described above, a large number of variants which are obvious to the person skilled in the art and which are produced by combining the individual features of the invention are likewise possible.
