Description

[0001] A SEAT SYSTEM

[0002] Technical Field

[0003] The present invention relates to an intelligent and adaptive seat system which distributes the collision energy to different structures in the event of a rear-end collision and enables to reduce the risk of whiplash injury by reducing the impact load on the neck of the driver / passenger in a controlled manner.

[0004] Background of the Invention

[0005] Due to the complex structure of the neck, there are many different injury mechanisms. A neck injury that occurs when the backward movement of the neck is not properly limited, especially in rear-end collisions, is known as whiplash injury. Whiplash injury occurs particularly in the case of a rear-end collision of the vehicle wherein the person is located. It is therefore a different problem as it involves a sudden relative acceleration as opposed to a sudden relative deceleration as in other collisions. On the other hand, while forward movement of the neck in frontal collisions is limited by the thorax, there is no such anatomical limitation in backward movement. While the neck anatomy can tolerate forward movements, it has a weak characteristic against backward movements. In summary, a whiplash injury is a special type of injury caused by uncontrolled backward movement of the neck, the mechanism of which has not been fully identified.

[0006] Whiplash injury is one of the most common injuries in rear-end collisions in traffic accidents, which is generally characterized by neck pain due to the stress and strain on soft tissues. Although the sudden movements of the hips, waist and back parts of the passenger / driver are limited by being supported by the backrest of the seat at the moment of a rear-end collision, the neck freely continues its backward movement and the neck forms a so-called S -curve, which is an anatomically unnatural shape. Then, the head and neck hit the headrest of the seat, while the backrest of the seat tilts backwards, the body of the passenger / driver moves upwards, the neck support function of the seat is reduced, and the neck is bent backwards with respect to the body. In the later stage of the collision, the head and neck bounce forward again after hitting the headrest and this time a trauma occurs on the neck in the opposite direction of the initial movement. These harsh and sudden movements, which occur within an average of 100 - 200 milliseconds, cause neck injuries including paralysis, the effects of which can last a lifetime, and which are very difficult to heal and last for a long period by causing damage to the vertebrae and soft tissues in the neck.

[0007] Although whiplash injuries significantly reduce the quality of life, they may not be accurately included in accident statistics and do not attract much attention since they are usually not fatal and their effects may not appear immediately at the time of the accident but may appear some time after the accident. Despite this, the 2019 US Traffic Safety report states that rear-end collisions are the second highest cause of injury with 24.1% after frontal collisions. Economically, it is stated that within the European Union, the problems related to whiplash injuries, which have serious effects on insurance companies and individuals both in terms of workforce loss and health expenditures, are experienced by an average of 800000 people annually and cause an economic loss of 10 billion Euros.

[0008] A headrest was added to the upper part of the seat in the 1960s for protection against whiplash injuries. The headrest, which is standard in most vehicles today, is a passive mechanical part that tries to reduce the risk of whiplash injury by limiting the backward movement of the neck. The serious decrease in the performance of the fixed headrest depending on the seating position has led to the search for different solutions since the late 90s. In order to increase the performance of the headrest, a reactive headrest that moves forward with the pressure of the back on the backrest of the seat in the event of a collision was designed. This mechanical design, which uses a 4-bar mechanism, aims to limit the movement of the neck by bringing the headrest closer to the occupant in the event of a collision. The success rate of the system named SAHR (SAAB - Active Head Restraints), developed under the leadership of SAAB, is stated as 43%.

[0009] Another mechanical design is a system called WHIPS (Whiplash Protection System), developed by Volvo. In this design, the seat moves slightly backwards under the collision load and the backrest can recline up to 15 degrees due to deformed fasteners. WHIPS is designed for impact loads with a speed difference of 10-20 km / h and is stated to have a success rate of up to 49%.

[0010] The designs against whiplash injuries in the literature are substantially based on the designs of SAAB and Volvo. While a significant number of these designs aim to keep the headrest in an appropriate position in a similar way to the design of SAAB, a small number of them try to reduce the impact load with the movement of the seat in a similar way to the design of Volvo.

[0011] In the mid-2000s, Mercedes and BMW designed systems in which the headrest part is integrated into the seat with pre-tensioned springs. In these systems, which focus on the headrest, the springs are released during a collision above a certain severity, pushing the headrest rapidly and bringing it closer to the head and neck area of the driver / passenger.

[0012] The studies carried out in the past 15 years are as follows: an electromechanical design in which electric motors are used in order to enable the headrest to continuously remain at an optimum distance from the head of the driver / passenger. In another study, it was aimed to reduce the impact load with an element placed between the seat and the vehicle floor, which deforms due to the severity of the collision as the seat slides. The system included in the prior art literature with the highest success rate in reducing the risk of whiplash injury is a design wherein a sliding mechanism having a spring and damper that is placed between the seat and the vehicle floor and reduces the impact load as the seat slides is used together with a damper having a non-linear spring constant in the mechanism that reclines the backrest.

[0013] A significant proportion of previous solutions developed against the risk of whiplash injury have focused solely on headrest design. However, it is known that the positioning adjustment of the headrest with respect to the head of the driver / passenger can significantly change the success rate of whiplash injury prevention, and that an incorrectly adjusted headrest may increase whiplash injury risk instead of decreasing it. On the other hand, there are publications indicating that the headrest alone may not provide adequate protection against whiplash injury even when optimum positioning is provided, and that the movement of the neck should be limited by reducing the energy transferred to the seat and neck due to the collision in the whole seat.

[0014] Prior art designs included in the literature, which do not only focus on headrest design but also aim to reduce the whiplash injury risk by seat movement, have a passive mechanism or a specific set of parameters that are predetermined offline. These systems with fixed stiffness and damping characteristics are adjusted according to an average occupant weight and the most probable collision impact. Therefore, these prior art mechanisms developed against whiplash injuries are designed based on a fixed weight and a fixed collision severity. Although the said mechanisms demonstrate an acceptable success rate under impact loads close to the most probable collision severity for a driver / passenger with a weight close to the average, which is their design point, the performance decreases as the variables move away from the design point. In the case of a heavier driver / passenger or a more severe collision, the prior art system quickly reaches the end of its movement range and may stop suddenly since it cannot provide enough resistance to absorb the energy from the collision as it is designed for an average weight person and average collision severity. Similarly, when encountered with a lighter driver / passenger or a collision of lower severity, the prior art mechanism may cause the driver / passenger to be subjected to excessive forces by acting more aggressive than necessary. Therefore, the performance of the prior art decreases significantly as you move away from the design points. Even in some cases, it is known that prior art designs may cause additional harm rather than benefit.

[0015] The Great Britain patent document no. GB2570689A, an application included in the state of the art, discloses a vehicle seat mounting system.

[0016] Summary of the Invention

[0017] An object of the present invention is to realize an intelligent and adaptive seat system which distributes the collision energy to different structures in the event of a rear-end collision and enables to reduce the risk of whiplash injury by reducing the impact load on the neck of the driver / passenger in a controlled manner.

[0018] Another object of the present invention is to realize a system which enables the acceleration and amplitude of movement of the neck caused by the energy transferred to the neck during a collision to be maintained at a level tolerable by the anatomy of the neck by being reduced compared to the prior art by means of the design developed to reduce the risk of whiplash injury.

[0019] A further object of the present invention is to realize a system which helps to reduce the risk of whiplash injury by enabling the loads on the neck to be adaptively reduced under varying collision severities.

[0020] A further object of the present invention is to realize a system which makes it possible to manage the energy by controlling the distribution optimization of the energy resulting from the collision in real time with the semi-active damper working together with the backrest part of the seat and the reclining element, and to reduce the negative effects of the forces that may cause whiplash injury, especially the shear force in the rear direction acting on the neck, by enabling the seat to accelerate in a controlled manner relative to the vehicle with this energy.

[0021] A further object of the present invention is to realize a system which increases the protection capability of the headrest without changing the standard headrest design, thus making it easily applicable to current vehicles.

[0037] In a preferred embodiment, the vehicle floor (2) included in the inventive seat system (1) has a radar / lidar sensor that is located at the rear of the vehicle and enables the approach speed and vehicle size / mass of the vehicle approaching and colliding the vehicle from behind to be estimated and the collision dynamics to be calculated.

[0038] In a preferred embodiment, the seat (3) included in the inventive seat system (1) has a position measuring device that measures amount and rate of the instantaneous displacement of the passenger / driver sitting thereon with respect to the vehicle floor (2). In a preferred embodiment, the seat (3) has a weight sensor that enables the weight of the passenger / driver sitting thereon to be detected. The seat (3) is connected to the vehicle floor (2) by means of the sliding element (7) and the damper (8).

[0039] In a preferred embodiment, the reclining element (6) included in the inventive seat system (1) has an angle meter that enables the angular change of the backrest (4) to be detected in the event of a rear-end collision of the vehicle.

[0040] The sliding element (7) included in the inventive seat system (1) may have a position measuring device for measuring the instantaneous sliding amount of the seat (3). The sliding element (7) comprises a groove or rail in order to enable the seat (3) to move horizontally on the vehicle floor (2).

[0041] The damper (8) included in the inventive seat system (1) is configured to enable the collision impact applied to the seat to be dampened by being released from the effect of the breakable element (9) when the breakable element (9) breaks above a certain collision severity. The damper (8) may be used in combination with spring-dampers or with materials and systems that can absorb energy by being deformed. In one embodiment of the invention, the damper (8) is a magnetorheological (MR) damper. A magnetorheological fluid is a dampener liquid and is a semi-active energy absorbing element. MR dampers comprise a carrier fluid similar to mineral oil comprising particles that can be polarized under a magnetic field. The rheological properties of this fluid can be controlled by changing the potential difference on the electronic device (10), thus the desired reaction force can be obtained. The management of the energy resulting from the collision can be adaptively performed with this control capability, thus the risk of whiplash injury is reduced. The fact that the MR fluid has a low time constant allows this control to be performed in real time.

[0042] In a preferred embodiment of the invention, the breakable element (9) included in the seat system (1) is located between the seat (3) and the vehicle floor (2) and is configured to allow horizontal movement of the seat (3) under the influence of the damper (8) by breaking above a certain collision severity. The breakable element (9) is located between the backrest (4) and the seat (3) and is configured to allow rotational movement of the backrest (4) by breaking above a certain collision severity. The breakable element (9) prevents the movement of the seat (3) and the activation of the damper (8) up to a certain collision severity. The breakable element (9) is configured to prevent the movement of the backrest (4) up to a certain collision severity. The breakable element (9) has a connection place or shape in such a way as to prevent the movement of the seat (3). In the event that the breakable element (9) is not deformed by the severity of the collision, i.e. does not break, the energy absorption resulting from the collision is not mitigated by the damper (8) and is transferred to the seat (3) and the reclining element (6). The breakable element (9) is used in order to enable the damper (8) to be activated in high severity collisions and the seat (3) to remain stable in low severity collisions. The breakable element (9) is configured to enable the seat (3) to move in the opposite direction relative to the movement of the vehicle under the effect of the collision impact relative to the ground and the damper (8) in the event that it breaks upon being subjected to a high severity collision. The electronic device (10) included in the inventive seat system (1) is a device in the form of an in-vehicle computer. The electronic device (10) is configured to enable driver / passenger weight data to be inputted manually or automatically by means of sensors. The electronic device (10) is configured to enable the weight of the passenger / driver sitting on the seat (3) to be retrieved from the weight sensor. In a preferred embodiment, the electronic device (10) is configured to enable data regarding the estimation of the approach speed and vehicle size / mass of the vehicle that collides into the vehicle from behind and collision dynamics to be retrieved from the radar / lidar sensor. The electronic device (10) is configured to enable data regarding the amount and rate of instantaneous displacement of the seat with respect to the vehicle floor (2) to be retrieved from the position measuring device. The electronic device (10) is configured to enable the angular data regarding the angular change of the backrest (4) in the event of a rear-end collision of the vehicle to be retrieved from the angle meter. The electronic device (10) is configured to transmit the obtained data regarding the vehicle to the processor (11). The electronic device (10) is configured to enable the potential difference or current values that should be applied to the damper (8) in order to manipulate the impact load that will be applied to the neck of the passenger / passenger due to the collision according to the driver / passenger weight, collision severity, angular change of the backrest (4) and position change of the seat (3) to be inputted automatically as parameter sets or by being calculated by the processor (11).

[0043] The processor (11) included in the inventive seat system (1) is configured to keep a record of the data obtained by the electronic device (10) regarding the vehicle and the data inputted via the electronic device (10). The processor (10) is configured to enable the data received regarding the vehicle in the event of a severe collision and the potential difference and current values that should be applied to the damper (8) to be determined automatically by using instantaneous and real-time parameter sets. The processor (10) is configured to enable the calculated potential difference value to be transmitted to the damper (8) and to be applied. Industrial Application of the Invention

[0044] In a first preferred embodiment of the inventive system (1), the driver / passenger weight is manually inputted into the electronic device (10). The collision severity is manually inputted into the electronic device (10) in advance, depending on the expected traffic situation and statistics. The pre-calibrated potential difference according to the respective weight and collision severity is applied to the damper (8). The impact load resulting from the collision is manipulated by the damper (8) applying a certain amount of force to the seat (3) under the applied potential difference, the amount of force and moment acting on the neck of the driver / passenger is reduced, and therefore the risk of whiplash injury is reduced. Since the potential difference applied to the damper (8) is the input of the electronic device (10), the system (1) can be adjusted offline accordingly for any collision severity and driver / passenger weight, and the system (1) is enabled to be easily adapted to the new driver / passenger or expected collision severity without changing the design.

[0045] In a second preferred embodiment of the inventive system (1), the weight of the driver / passenger is automatically detected with the help of a sensor that can be placed on the seat (3) and fed to the electronic device (10). The severity of the collision is fed to the electronic device (10) by being automatically determined by an estimated collision dynamics calculation after the detection of approach speed and vehicle size / mass by a sensor similar to a radar / lidar at the rear of the vehicle. A pre-calibrated potential difference / current according to the respective weight and collision severity is applied to the damper (8). The impact load resulting from the collision is manipulated by the damper (8) applying a certain amount of force to the seat (3) based on the applied potential difference, the amount of force and moment acting on the neck of the driver / passenger is reduced, and therefore the risk of whiplash injury is reduced. An appropriate damping force that will be applied to the seat (3) is adaptively determined by feeding the automatically determined driver / passenger weight and collision severity to the electronic device (10). Thus, in the case of different collision severities or persons with different driver / passenger weights, the success rate of reducing the risk of whiplash injury is adaptively ensured.

[0046] In a third preferred embodiment of the inventive system (1), a position measuring device is used in order to measure the amount and rate of instantaneous displacement of the seat (3) with respect to the vehicle floor (2). The force applied by the damper (8) to the seat (3) is adjusted by the processor (11) in real time and automatically calculating the potential difference that will be applied on the damper (8) according to the desired acceleration profile fed to the electronic device (10) depending on the amount and rate of displacement of the seat (3) at the moment of collision, the impact load resulting from the collision is manipulated, the amount of force and moment acting on the neck of the driver / passenger is reduced, and therefore the risk of whiplash injury is reduced. Thus, in the case of different collision severities or persons with different driver / passenger weights, the success rate of reducing the risk of whiplash injury is adaptively maintained at the optimum level.

[0047] In a fourth preferred embodiment of the inventive system (1), a sensor suitable for measuring the amount and rate of instantaneous displacement of the seat (3) with respect to the vehicle floor (2) and a sensor suitable for detecting the angular change of the backrest (4) are used. The force applied by the damper (8) to the seat (3) is adjusted by the processor (11) in real time and automatically calculating the potential difference that will be applied on the damper (8) depending on the amount and rate of displacement of the seat (3) at the moment of collision together with the amount of angular displacement of the reclining element (6) and backrest (4), the impact load resulting from the collision is manipulated, the amount of force and moment acting on the neck of the driver / passenger is reduced, and therefore the risk of whiplash injury is reduced. Since the reclining amount of the backrest (4) provides the possibility to simulate the equivalent mass of the driver / passenger and the seat (3) as a whole under varying impact load, the calculation of the amount of force desired to be applied to the seat (3) by the damper (8) can be performed adaptively.

[0048] The said system (1), which is introduced to reduce the risk of whiplash injury, is in an integrated structure and enables the optimal distribution and management of the energy resulting from the collision by working together with the semi-active / active damper (8), which is a part of the adaptive system, the backrest (4) part of the seat (3) and the reclining element (6), which are the other parts of the system (1). With the energy generated by the collision, it is enabled to accelerate the seat (3) in a controlled manner in the opposite direction relative to the movement of the vehicle. In this regard, the system (1), which solves an acceleration problem, has freedom of movement in the backward direction on the horizontal axis in order to enable the backward movement of the seat (3).

[0049] The above-mentioned different uses of the present invention may be used in combination with each other or separately or in any combination of these forms and may be used in new uses not expressly mentioned herein but which are a natural consequence of such uses.

[0050] Within these basic concepts; it is possible to develop various embodiments of the inventive “A Seat System (1)”; the invention cannot be limited to examples disclosed herein and it is essentially according to claims.
