Description

Technical Field

[0001] The present invention relates to an automotive seat and a spinal support device for an automotive seat. Background Art

[0002] Currently in this technical field, when the backrest of an automotive seat is in normal use, it can be adjusted according to the riding habits of the driver and passengers. However, in existing safety regulation tests, the seat backrest is adjusted to the designed position (generally about 25 degrees) to evaluate the injury to the crash dummy. In actual use, during a collision, the seat backrest of the driver and passengers may not be adjusted to the designed position. For example, during a collision, the occupant is lying or semi - lying on the seat, and at this time, the occupant's spine will be under great pressure, resulting in injury.

[0003] With the development of automotive intelligent, autonomous driving, or driverless technologies, the attention of the driver inside the vehicle will be partially or completely liberated. The drivers and especially the passengers on the co - driver side inside the vehicle will have more possible sitting postures. Generally, the sitting postures can be classified into three types: 1) normal driving sitting posture, 2) working sitting posture, and 3) leisure sitting posture. Specifically, the normal driving sitting posture means that the driver and passengers fully focus on the driving condition of the vehicle. Generally, the designed position for adjusting the seat backrest of the seat is about 25 degrees; for the working sitting posture, the driver and passengers do not focus on the driving condition of the vehicle and can work or entertain inside the vehicle, and the seat backrest is adjusted to about 45 degrees; for the leisure sitting posture, the driver and passengers completely do not focus on the driving of the vehicle and can close their eyes to rest, and the seat backrest is adjusted to 60 degrees or even a larger angle.

[0004] In the working sitting posture or leisure sitting posture (semi - lying or full - lying sitting posture), when a vehicle has a frontal collision, the torso of the driver and passengers will slide downward along the seat backrest due to inertia. The seat pan of the seat supports the occupant, and the seat belt waistband on the seat restrains the pelvis of the driver and passengers, resulting in the relative movement and extrusion between the upper torso and the pelvis of the driver and passengers. Existing research and tests show that such a situation will cause the spine to be compressed and is likely to form incurable or even life - threatening injuries.

[0005] However, in existing technical solutions, in addition to the seat pan of the automotive seat supporting the pelvis of the driver and passengers, the seat backrest only supports the torso of the driver and passengers, and there is no additional support structure for the torso along the direction of the seat backrest. The support mainly depends on the occupant's own spine. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defect that it is difficult to protect the occupant's spine during a collision in the existing automotive seats, and to provide an automotive seat and a spinal support device for an automotive seat.

[0007] The present invention solves the above technical problems through the following technical solutions:

[0008] A spinal support device for an automotive seat, characterized in that the spinal support device includes: a support body, one end of the support body is connected to the automotive seat, and the other end of the support body extends from the automotive seat to under the armpit of the occupant and is used to support under the armpit of the occupant.

[0009] In this solution, adopting the above structural form, the support body of the spinal support device can be lifted or turned up to support under the armpit of the occupant in a normal driving sitting posture to relieve the pressure on the spine; when the vehicle occupants are in a working sitting posture (semi-reclined) and a leisure sitting posture (fully reclined), the spinal support device makes up for the lack of restraint of the occupants along the seat back direction. Through the support under the armpit, the spinal pressure can be reduced and the driving and riding comfort can be improved; at the same time, when a frontal or side collision occurs, the spinal support device improves the movement posture of the occupants, relieves the spinal pressure, and improves the safety of the occupants.

[0010] Preferably, the spinal support device further includes an adjustment part, one side of the adjustment part is connected to the automotive seat, the other side of the adjustment part is connected with the support body, and the support body moves on the automotive seat through the adjustment part to be used for adjusting the distance between the support body and under the armpit of the occupant.

[0011] In this solution, adopting the above structural form is beneficial to enabling the occupant to obtain a more comfortable support effect, and at the same time is beneficial to enabling the spinal support device to meet the support requirements of occupants with different body types and different body sizes.

[0012] Preferably, the adjustment part further includes an adjustment body and an adjustment track, the adjustment track is connected to the backrest of the automotive seat, the adjustment body is slidably connected to the adjustment track, one end of the support body is fixedly connected to the adjustment body, and the other end of the support body extends from the automotive seat to under the armpit of the occupant.

[0013] In this solution, adopting the above structural form, the spinal support device slides the adjustment body on the adjustment track to change the distance between the support body and under the armpit of the occupant. The adjustment part adopting such a design has a simple structure and is easy to manufacture, and can meet the actual adjustment requirements of the occupants.

[0014] Preferably, the adjustment part further includes a locking mechanism. When the support body supports under the armpit of the occupant, the locking mechanism is used to fix the support body at a corresponding position on the adjustment part.

[0015] In this solution, with the above structural form, the positioning function of the locking mechanism on the support body makes it difficult for the support body to slip when it is in a supported state under a certain load, enabling the occupant to obtain a certain amount of support force during use.

[0016] Preferably, the locking mechanism fixes the support body. When the pressure value received by the support body is greater than its set value, the support body slides or deforms, and the support body continues to support under the occupant's armpit along with the sliding or deformation.

[0017] In this solution, with the above structural form, such a design of the support body can provide sufficient support force for the occupant while also having a certain energy absorption effect. The support body absorbs the excessive pressure on the occupant's spine through sliding or deformation to protect the occupant's spine.

[0018] Preferably, the spinal support device further includes a damping component or a deformable mechanism, which acts on the support body. When the pressure value received by the support body is greater than the set value, the support body slides or deforms on the vehicle seat.

[0019] In other embodiments with the above structural form, during the process of the support body sliding downward or deforming, the damping component or the deformable mechanism provides a certain resistance to the support body, playing an energy absorption role to absorb the pressure on the occupant's spine during downward movement and protecting the occupant's spine.

[0020] Preferably, the number of the support bodies is two. The two support bodies are respectively a first support body and a second support body. The first support body is connected to one side of the vehicle seat, and the second support body is connected to the other side of the vehicle seat. The first support body and the second support body respectively extend to under the occupant's armpits and support under the occupant's armpits.

[0021] In this solution, with the above structural form, the support body is of a split design, set as a first support body and a second support body. During use, the first support body and the second support body can move on the corresponding adjustment parts respectively to meet the different support requirements under the occupant's two armpits. Such a split design of the support body enables the occupant to adjust the support bodies under the two armpits separately, which is beneficial to meeting the different support requirements under the two armpits of different occupants.

[0022] Preferably, the support body is movably connected to the vehicle seat and has a first state and a second state. In the first state, the extended end of the support body extends from the vehicle seat to under the occupant's armpit and supports under the occupant's armpit. In the second state, the extended end of the support body retracts from under the occupant's armpit.

[0023] In the present scheme, the above-mentioned structural form is adopted, and the occupant can switch the state of the support body according to the actual situation. When the angle between the seat back of the car seat and the vertical direction is too large, the occupant will flip up the support body according to his or her actual situation, so that the support body is supported on both sides of the occupant, that is, the support body enters the first state at this time; when the angle between the seat back of the car seat and the vertical direction is small, the occupant can choose to flip up the support body to put the support body into the first state, or choose to fold the support body on both sides of the car seat to put it in the second state. The support body can switch the state according to the actual situation. Such a design makes the use of the support body more convenient and flexible.

[0024] Preferably, the support body is made of plastic material or elastic material.

[0025] In this solution, the above-mentioned structural form is adopted. When the car collides sideways and the pressure on the occupants exceeds the force that the human body can withstand, the support body will absorb the kinetic energy of the driver and passengers through plastic deformation or elastic deformation of the material, improve the restraint posture of the driver and passengers, and cooperate with the side airbags, distal airbags, and air curtains to further reduce the injuries to the driver and passengers.

[0026] Preferably, the spinal support device further comprises a soft package, and the soft package is coated on the support body.

[0027] In the present solution, the above-mentioned structural form is adopted, and the soft package not only provides a better support experience for the occupant's armpits, but also the soft package can be fully deformed when subjected to force, so that it has a better fit with the occupant's armpits, and can provide better protection for the occupant during a collision.

[0028] A car seat is characterized in that the car seat adopts the above-mentioned spine supporting device for car seats.

[0029] In this solution, the above-mentioned structural form is adopted, and a spine support device is installed on the car seat. When the vehicle has a frontal collision, especially when the seat back angle is relatively large, such as when sitting for work or leisure, the occupant will slide down along the seat back under the action of inertia, and the support body under the armpit plays a supporting role in the occupant's sliding process. When the pressure on the support body exceeds the set value, the support body will plastically deform or elastically deform to absorb the inertia force on the occupant's torso, relieving the pressure on the occupant's spine. Similarly, when the vehicle has a side collision, the support body will also plastically or elastically deform to maintain the posture of the upper torso, and work together with the side airbag, distal airbag and air curtain to reduce the damage caused by secondary collision.

[0030] On the basis of being in accordance with the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present invention.

[0031] The positive and progressive effects of the present invention are as follows:

[0032] In the spinal support device of the vehicle seat in the present invention, in the normal driving sitting posture, the support body of the spinal support device can be lifted or turned up to support under the armpit of the occupant, so as to reduce the pressure on the spine; when the vehicle occupant is in the working sitting posture (semi-reclined) and the leisure sitting posture (fully reclined), the spinal support device makes up for the lack of restraint of the occupant along the seat back direction. Through the support under the armpit, the spinal pressure can be reduced and the driving and riding comfort can be improved; at the same time, when a frontal or side collision occurs, the spinal support device improves the movement posture of the occupant, relieves the spinal pressure, and improves the safety of the occupant.

[0044] The present invention will be more clearly and completely described below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0045] An embodiment of the present invention provides a spinal support device for a vehicle seat 4. As Figures 1-3 shown, the spinal support device includes: a support body 1, one end of the support body 1 is connected to the vehicle seat 4, and the other end of the support body 1 extends from the vehicle seat 4 to under the armpit of the occupant and is used to support under the armpit of the occupant.

[0046] With the above structural form, the spinal support device is installed on the frame of the backrest of the vehicle seat 4. The spinal support device is provided with a rod-shaped support body 1. One end of the support body 1 is a fixed end, and the support body 1 is fixedly connected to the vehicle seat 4. The other end of the support body 1 is a moving end, enabling the support body 1 to move relative to the vehicle seat 4. When the spinal support device is in a non-working state, the support body 1 folds on both sides of the vehicle seat 4, so as not to affect the activities of the vehicle occupants; when the spinal support device is in a working state, the occupant extends the support body 1 from both sides of the vehicle seat 4 to both sides of the armpits of the occupant by adjusting the moving end of the support body 1, and its position can be adjusted according to the body shape of the driver and passengers. In the normal driving posture, the support body 1 of the spinal support device can be lifted or turned up to support under the armpits of the occupant, so as to relieve the pressure on the spine; when the vehicle occupants are in the working sitting posture (semi-reclined) and the leisure sitting posture (fully reclined), the spinal support device makes up for the lack of restraint of the driver and passengers along the direction of the seat backrest. Through the support under the armpits, the spinal pressure can be reduced and the driving and riding comfort can be improved; at the same time, when a frontal or side collision occurs, the spinal support device improves the movement posture of the driver and passengers, relieves the spinal pressure, and improves the safety of the driver and passengers.

[0047] As a preferred embodiment, as Figures 1-3 shown, the spinal support device further includes an adjustment part 2. One side of the adjustment part 2 is connected to the vehicle seat 4, and the other side of the adjustment part 2 is connected with the support body 1. And the support body 1 moves on the vehicle seat 4 through the adjustment part 2 to adjust the distance between the support body 1 and the armpits of the occupant.

[0048] With the above structural form, one side of the adjustment part 2 on the spinal support device is fixedly connected to the frame of the backrest of the vehicle seat 4, and the other side of the adjustment part 2 is installed with the support body 1. When the spinal support device enters the working state, the occupant passes one end of the support body 1 through the armpits on both sides, so that the support body 1 abuts against the armpits of the occupant. At the same time, the other end of the support body 1 can slide on the adjustment part 2 to adjust the distance between the support body 1 and the armpits of the occupant, which is beneficial to enabling the occupant to obtain a more comfortable support effect, and is also beneficial to enabling the spinal support device to meet the support requirements of occupants with different body types and different body sizes.

[0049] As a preferred embodiment, as Figures 1-3 shown, the adjustment part 2 further includes an adjustment body and an adjustment track 21. The adjustment track 21 is connected to the backrest of the vehicle seat 4, the adjustment body is slidably connected to the adjustment track 21, one end of the support body 1 is fixedly connected to the adjustment body, and the other end of the support body 1 extends from the vehicle seat 4 to the armpits of the occupant.

[0050] With the above-mentioned structural form, an adjustment track 21 is provided in the adjustment part 2, and the adjustment track 21 is connected to the backrest of the car seat 4. An adjustment body is installed on the adjustment track 21, and the adjustment body can slide on the adjustment track 21. The adjustment body is fixedly connected to one end of the support body 1, and the other end of the support body 1 extends to the armpit of the occupant. The spinal support device changes the distance between the support body 1 and the armpit of the occupant by sliding the adjustment body on the adjustment track 21. The adjustment part 2 adopts such a design structure, which is simple and easy to manufacture, and can meet the actual adjustment needs of the occupants.

[0051] As a preferred implementation, Figures 1-3 As shown, the adjustment part 2 further includes a locking mechanism. When the support body 1 supports the armpit of the occupant, the locking mechanism is used to fix the support body 1 at a corresponding position on the adjustment part 2.

[0052] With the above-mentioned structural form, a locking structure is also provided on the adjustment part 2. When the occupant places the support body 1 against the armpit and adjusts it to a suitable position, the adjustment body fixedly connected to one end of the support body 1 also moves to a suitable position on the adjustment track 21. The locking mechanism positions the adjustment body so that the adjustment body is fixed on the adjustment track 21, thereby realizing that the locking mechanism fixes the support body 1 at a specific position on the adjustment part 2. The positioning effect of the locking mechanism on the support body 1 makes it difficult for the support body 1 to slip when it is under a certain load and in a supporting state, so that the occupant can obtain a certain supporting force during use.

[0053] As a preferred implementation, Figures 1-3 As shown, the locking mechanism fixes the support body 1. When the pressure value on the support body 1 is greater than the set value, the support body 1 slides or deforms, and the support body 1 continues to support the armpit of the occupant as it slides or deforms.

[0054] With the above structural form, when the occupant presses the support body 1 against the armpit and adjusts it to a proper position, the spinal support device positions the adjusting body through the locking mechanism, so that the locking mechanism fixes the support body 1 at a specific position on the adjusting part 2. At the same time, due to the structural form and material selection of the support body 1, the pressure bearing value of the support body 1 can be set. When the pressure received by the support body 1 is less than the set pressure bearing value, the support body 1 can provide sufficient support force for the occupant. However, when a vehicle collision occurs, to prevent the support force provided by the support body 1 to the occupant from exceeding the range that the occupant can bear, when the pressure value received by the support body 1 exceeds the set pressure bearing value, the support body 1 will slide downward or deform to absorb the pressure on the spine of the occupant during the downward movement, playing a protective role for the spine of the occupant. Such a design of the support body 1 can provide sufficient support force for the occupant and also has a certain energy absorption effect. The support body 1 absorbs the excessive pressure on the spine of the occupant by sliding or deforming to protect the spine of the occupant.

[0055] As a preferred embodiment, as Figures 1-3 shown, the spinal support device further includes a damping component or a deformable mechanism, which acts on the support body 1. When the pressure value received by the support body 1 is greater than the set value, the support body 1 slides or deforms on the vehicle seat 4.

[0056] In other embodiments, a damping component is provided inside the spinal support device. The damping component or the deformable mechanism is fixedly connected to the adjusting body and is positioned on the adjusting track 21 through the damping component or the deformable mechanism after the support body 1 is adjusted to a specific position. When a vehicle collision occurs and the pressure value received by the support body 1 is greater than the set value, the support body 1 slides downward or deforms on the vehicle seat 4 under the action of the pressure. During the process of the support body 1 sliding downward or deforming, the damping component or the deformable mechanism provides a certain resistance for the support body 1, playing an energy absorption role to absorb the pressure on the spine of the occupant during the downward movement, playing a protective role for the spine of the occupant.

[0057] As a preferred embodiment, as Figures 1-3 shown, the number of the support bodies 1 is two. The two support bodies 1 are respectively a first support body 11 and a second support body 12. The first support body 11 is connected to one side of the vehicle seat 4, and the second support body 12 is connected to the other side of the vehicle seat 4. The first support body 11 and the second support body 12 respectively extend to the armpits of the occupant and support the armpits of the occupant.

[0058] With the above structural form, the support body 1 is a split design, which is set as the first support body 11 and the second support body 12. The first support body 11 and the second support body 12 are respectively arranged on both sides of the vehicle seat 4. One ends of the first support body 11 and the second support body 12 are fixedly connected to the vehicle seat 4. The other ends of the first support body 11 and the second support body 12 respectively extend to the armpits on the corresponding side of the occupant, and support the armpits of the corresponding side of the occupant. At the same time, during use, the first support body 11 and the second support body 12 can respectively move on the corresponding adjustment parts 2 to meet the different support requirements for the armpits on both sides of the occupant. Such a split design of the support body 1 enables the occupant to adjust the support bodies 1 on both sides of the armpits independently, which is beneficial to meeting the different support requirements for the armpits on both sides of different occupants.

[0059] As a preferred embodiment, as Figures 1-3 shown, the support body 1 is movably connected to the vehicle seat 4 and has a first state and a second state; in the first state, the extended end of the support body 1 extends from the vehicle seat 4 to the armpit of the occupant and supports the armpit of the occupant; in the second state, the extended end of the support body 1 retracts from the armpit of the occupant.

[0060] With the above structural form, the support body 1 has a first state and a second state. When the angle between the seat back of the vehicle seat 4 and the vertical direction changes, the occupant can switch the state of the support body 1 according to the actual situation. For example, when the angle between the seat back of the vehicle seat 4 and the vertical direction is greater than 40 degrees, the occupant can turn up the support body 1 according to his own actual situation, and the support body 1 will extend from both sides of the vehicle seat 4 to the armpits of both sides of the occupant to support the armpits of the occupant, that is, at this time the support body 1 enters the first state; when the angle between the seat back of the vehicle seat 4 and the vertical direction is less than 40 degrees, the occupant can choose to turn up the support body 1 to make the support body 1 enter the first state, or can choose to fold the support body 1 on both sides of the vehicle seat 4 to make it in the second state. The support body 1 can switch the state according to the actual situation, and such a design makes the use of the support body 1 more convenient and flexible.

[0061] As a preferred embodiment, as Figures 1-3 shown, the material of the support body 1 is a plastic material or an elastic material.

[0062] With the above-mentioned structural form, the support body 1 is made of plastic material or elastic material, which not only makes the support body 1 structure lighter, but also when the vehicle has a side collision, the spine support device can effectively restrain the driver and passengers to avoid lateral impact in the vehicle. Similarly, when restrained on the side, the spine support device can also have an energy-absorbing effect. When the lateral force exceeds the force that the human body can withstand, the support body 1 will absorb the kinetic energy of the driver and passengers through plastic deformation or elastic deformation of the material, improve the restraint posture of the driver and passengers, and cooperate with the side airbags, distal airbags, and air curtains to further reduce the injuries to the driver and passengers.

[0063] As a preferred implementation, Figures 1-3 As shown, the spinal support device further includes a soft package, which is coated on the support body 1.

[0064] With the above-mentioned structural form, a soft package is covered on the outside of the support body 1. When the support body 1 is against the armpit of the occupant, the soft package on the support body 1 is in contact with the armpit of the occupant. The soft package not only provides a better support experience for the armpit of the occupant, but also the soft package can be fully deformed when subjected to force, so that it has a better fit effect with the armpit of the occupant, and can provide better protection for the occupant during a collision.

[0065] An embodiment of the present invention provides a vehicle seat 4, such as Figures 1-3 As shown, the vehicle seat 4 adopts the above-mentioned spine supporting device for the vehicle seat 4 .

[0066] With the above-mentioned structural form, a spinal support device is installed on the car seat 4. When the vehicle has a frontal collision, especially when the seat back angle is relatively large, such as when sitting for work or leisure, the occupant will slide down along the seat back under the action of inertia, and the support body 1 under the armpit will support the occupant in the process of sliding down. When the pressure on the support body 1 exceeds the set value, the support body 1 will plastically or elastically deform to absorb the inertia force on the occupant's torso, relieving the pressure on the occupant's spine. Similarly, when the vehicle has a side collision, the support body 1 will also plastically or elastically deform to maintain the posture of the upper torso, and work together with the side airbag, distal airbag and air curtain to reduce the damage caused by secondary collision.

[0067] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
