Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings.

The use of the terms "first," "second," and the like in one or more embodiments of the present description does not denote any order, quantity, or importance, but rather the terms "first," "second," and the like are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.

In order to facilitate understanding of the automobile provided by the embodiment of the application, an application scene of the automobile is first described. The automobile seat provided by the embodiment of the application is applied to vehicles, and particularly can be used as a rear seat of a passenger car. When an accident such as a rear-end collision occurs, the automobile instantaneously obtains a large forward acceleration, and the seat back generates a large impact on the passenger under the action of the acceleration, so that the seat back plays a critical role in protecting the passenger, in particular to protecting the waist and back of the passenger. Therefore, the application provides the automobile seat, which is used for improving the safety performance of the automobile seat and improving the riding comfort.

In this embodiment, the rear seats of the automobile are taken as an example for unfolding and describing, and the side pillars of the automobile in this embodiment may be the C pillars of the automobile; in some large vehicles, such as a common seven-seat vehicle, the side pillar of the vehicle in this embodiment may also be a D pillar of the vehicle.

In order to describe the automobile seat provided by the embodiment of the application conveniently, the main body structure of some automobile seats is introduced. Referring to fig. 1, the car seat includes a seat back i, a headrest ii, a seat cushion iii, and the like. The seat back I is mainly used for supporting the waist and back of an occupant and comprises a seat back framework and a foaming assembly wrapped on the seat framework. In relation to the safety performance of a car seat, the main component involved is the seat back i, and thus, the seat back i provided by the embodiments of the present application will be described in detail below.

For convenience in description of the structure of the seatback i, a width direction and a height direction of a seatback frame are defined, wherein the width direction of the seatback frame refers to a direction parallel to a vehicle body width direction; the height direction of the seat back framework refers to the direction that one end of the seat back I connected with the seat cushion III points to the headrest II.

Referring to fig. 2, fig. 2 is a schematic diagram of a foaming assembly according to an embodiment of the present application. The foaming assembly 1 of the seat backrest I covers the seat backrest framework 2. Specifically, the foam assembly 1 is fixed to the seat back frame 2 on the side facing the occupant. The automobile seat back frame 2 is typically a metal frame that provides excellent rigid support for the lumbar backs of the occupants while they are seated. The foam assembly 1 provides protection for the occupant while also compromising the comfort of the seat back.

The seat foam assembly 1 may be molded from a variety of materials such as foamed polyurethane (PUR foam), foamed polypropylene (EPP foam), etc., and may be adhered, snapped, etc., to cover the seat back frame 2.

According to the automobile seat provided by the embodiment of the application, one end of the foaming assembly 1, which is close to the automobile side column, extends towards the automobile side column and abuts against the automobile side column. The end of the foaming assembly 1 extending toward the side pillar of the automobile is named as an extension end 11, and as shown in fig. 2, the extension end 11 of the foaming assembly 1 fully utilizes the space between the conventional seat back and the side pillar of the automobile, and the width of the seat back is increased as much as possible in a limited space. In the event of an accident, a wider car seat can provide a larger support area for the occupants; especially, the extension end 11 greatly improves the protection of shoulder blades and arm parts on one side of the passenger, and greatly improves the safety performance of the automobile seat. Meanwhile, the wider seat backrest also gives consideration to the comfort of the automobile seat during normal leaning and sitting.

In order to give consideration to the tipping performance of the seat back, the extending end 11 does not cover the whole side edge of the automobile seat facing the automobile side column, and a notch 111 avoiding the rotating shaft of the seat back frame 2 is arranged at the extending end 11 at a position close to the rotating shaft of the seat frame, namely, a position of the foaming assembly 1 close to the seat cushion, so that the seat back I tips smoothly. As in fig. 1, the position where the extended end 11 interferes with the seat cushion of the car seat when the seat back is tipped over, the car seat cushion is also reserved with grooves, the sharp angle below the extension end 11 of the foaming assembly 1 can extend into the groove, so that the overturning of the seat back is not interfered, and the overturning flexibility of the seat back is improved.

Referring to fig. 3, fig. 3 is a schematic side view of a foaming assembly according to an embodiment of the present application. In order to match the shape of the automobile side column, the problem that the automobile side column cannot be installed due to interference when the foaming assembly 1 is assembled is avoided, the extending end 11 is wedge-shaped at the lower end of the automobile seat frame in the height direction, and the thickness of the extending end 11 gradually decreases in a specific wedge-shaped mode along the direction of the foaming assembly 1 pointing to the automobile side column. And for the extension end 11 having a wedge shape, the automobile side column also has a supporting effect on the extension end 11 to better support the occupant at the time of accident, thereby reducing injury to the occupant.

As an alternative embodiment, a foam reinforcement is embedded inside the extension 11. Since the back of the extension end 11 of the foam assembly 1 is not supported by the seat back frame 2 and the extension end 11 is wedge-shaped, the extension end 11 may be excessively crushed due to insufficient rigid support during an accident, thereby affecting the safety of the occupant. The foam reinforcement is buried, so that the supporting rigidity of the extension end 11 can be improved from the inside of the extension end 11, and the extension end 11 is not easy to collapse while the passenger gets softer contact experience when leaning against the seat, so that the riding comfort of the passenger is improved. The concrete foam reinforcement may be in the form of reinforcing plates, reinforcing wires, etc.

As an alternative embodiment, the foam reinforcement embedded inside the extension 11 is an L-shaped steel wire (not shown in the figures). It will be appreciated that, for the extending end 11 made of soft foam, the edge and corner positions thereof are more prone to collapse when sitting, so that the steel wire is L-shaped along the extending arrangement of the extending end 11 near the edge of one side of the automobile side post, thereby effectively enhancing the rigid supporting strength of the extending end 11 and ensuring that the extending end 11 is not prone to excessively collapse. And the foaming reinforcement adopts steel wires, and has the characteristics of simple preparation and light structure.

Of course, the foam reinforcement may be a metal plate or other shaped steel wire, etc., without affecting the support strength and comfort. Meanwhile, in order to strengthen the whole extension end 11, more reinforcing members may be provided inside the extension end 11, for example, a plurality of reinforcing steel wires may be provided at intervals in the height direction of the seat back frame 2.

The extension end 11 and the reinforcement structure which may be provided therein, the supporting area of the seat back is increased by increasing the width of the seat back, so that the seat back can cover the occupant with a larger area when an accident occurs, and the safety performance of the car seat is improved.

Referring to fig. 4, fig. 4 is a schematic view of a weakening groove according to an embodiment of the present application. The foaming assembly 1 comprises a back support area 12 and a lumbar support area 13, wherein the back support area 12 and the lumbar support area 13 are arranged from top to bottom along the height direction of the seat back frame 2, namely, the back support area 12 is positioned above the lumbar support area 13 along the height direction of the seat back frame 2.

The automobile seat provided by the embodiment of the application further comprises a longitudinal weakening groove 14 arranged on one side of the foaming assembly 1 facing the seat back skeleton 2, wherein the longitudinal weakening groove 14 is arranged in an extending manner along the height direction of the seat back skeleton 2. Further, the longitudinal weakening grooves 14 are located in the back support region 12 and the lumbar support region 13.

In the event of a traffic accident, such as a rear-end collision, the occupant instantaneously generates a large acceleration in the direction of the foam assembly 1 and will hit the foam assembly 1 hard, i.e., the foam assembly 1 receives a whipping force. At this time, the longitudinal weakening groove 14 deforms to absorb part of whipping force, so that the cushioning effect of the foaming assembly 1 on the occupant can be enhanced, and whipping protection can be further formed on the occupant.

In an embodiment of the application, the depth of the longitudinal weakening grooves 14 in the portion of the back support area 12 is smaller than the depth of the longitudinal weakening grooves 14 in the portion of the lumbar support area 13. When the above structure is adopted, the supporting strength of the foam assembly 1 corresponding to the back supporting area 12 and the lumbar supporting area 13 can be changed by the difference in the depth of the longitudinal weakening grooves 14. In the back support region 12 where the longitudinal weakening grooves 14 are shallower, the longitudinal weakening grooves 14 weaken the support strength of the back support region 12 less; conversely, in the lumbar support region 13 where the longitudinal weakening grooves 14 are deeper, the longitudinal weakening grooves 14 weaken the support strength of the lumbar support region 13. So that the support strength of the back support region 12 is greater than the support strength of the lumbar support region 13. By supporting the stronger back support region 12, the back of the occupant can be subjected to more impact force, while the weaker lumbar support region 13 can provide stronger cushioning to the lumbar region of the occupant that is vulnerable to injury, to enhance protection of the occupant's lumbar region. In addition, the strong back support region 12 can effectively prevent the back support region 12 from being excessively crushed to influence the riding experience when the occupant sits down under normal conditions.

It is apparent that the longitudinal weakening groove 14 in the embodiment of the present application gradually deepens from top to bottom in the height direction of the seat back frame 2, and thus the change of the cushioning degree of different areas of the longitudinal weakening groove 14 when an accident or a normal sitting occurs gradually occurs, the cliff-type depression is not generated, and the uncomfortable feeling caused thereby can be reduced.

With continued reference to fig. 4, the longitudinal weakening grooves 14 include a main longitudinal weakening groove 141 and an auxiliary longitudinal weakening groove 142, wherein the main longitudinal weakening groove 141 is provided at a middle portion in the width direction of the seatback frame 2, which mainly corresponds to a region supporting the spine of the occupant. The number of the auxiliary longitudinal weakening grooves 142 is plural, and the plural auxiliary longitudinal weakening grooves 142 are arranged on both sides of the main longitudinal weakening groove 141, and when specifically arranged, the auxiliary longitudinal weakening grooves 142 are arranged at intervals along the width direction of the seatback frame 2 so as to support the back region and the waist region on both sides of the spine of the occupant. The weakening strength of the main weakening groove is larger than that of the auxiliary weakening groove, so that the main weakening groove and the auxiliary weakening groove are matched in the back supporting area, and impact force can be born through the shoulder neck area of the back of a user and the areas on the two sides of the spine when the impact force is transmitted to the passenger, and the spine of the passenger is protected.

As an alternative, the auxiliary weakening grooves on either side of the main longitudinal weakening groove 14 are all arranged to the width edge region of the seat back frame 2, so that the supporting force along the seat back frame 2 can be gradually changed from weak to strong from middle to two sides, a gradual change effect is formed, and the comfort of passengers is improved.

When the weakening strength of the main weakening groove is greater than that of the auxiliary weakening groove is specifically achieved, a form may be adopted in which the width of the main longitudinal weakening groove 141 in the width direction of the seatback frame 2 is greater than that of the auxiliary longitudinal weakening groove 142 in the width direction of the seatback frame 2, so as to enhance the protection of the occupant's spine.

As an example, as in fig. 4, a main longitudinal weakening groove 141, a first auxiliary longitudinal weakening groove 142, a second auxiliary longitudinal weakening groove 142, a third auxiliary longitudinal weakening groove 142 are provided. The main weakening groove is positioned at the central position, when the foaming assembly 1 is whipped, stronger buffering is provided at the spinal column of the passenger and the position close to the spinal column, and the opposite side positions are used as assistance, so that a certain buffering can be provided, and the comfort of the passenger when the passenger leans against the seat at ordinary times can be avoided because the collapse amount of the backrest assembly is too large.

It should be understood that the number of the auxiliary longitudinal weakening grooves 142 may be adjusted according to the size, hardness, etc. of the foaming assembly 1, for example, two auxiliary longitudinal weakening grooves 142 may be disposed on both sides of the main longitudinal weakening groove 141, respectively.

As an alternative embodiment, with continued reference to fig. 4, on the side of the foam assembly 1 facing the seatback frame 2, a transverse weakening groove 15 parallel to the width direction of the seatback frame 2 is further provided on the foam assembly 1. Specifically, the lateral weakening grooves 15 are located on both sides of the longitudinal weakening groove 14 in the seat back width direction. The transverse weakening grooves 15 respectively provide certain auxiliary buffering at two sides of the foaming assembly 1 along the width direction of the backrest framework, so that the safety performance of the automobile seat is further improved.

Illustratively, the foaming assembly 1 as shown in fig. 4 is provided with three lateral weakening grooves 15 on both sides in the width direction of the back frame, respectively. It will be appreciated that the same principle as described above for the longitudinal weakening grooves 14, the number and width of the transverse weakening grooves 15 can be adapted according to the need to provide cushioning strength when the stiffness of the foaming assembly 1 is different.

The transverse weakening groove 15 in fig. 4 also extends to the extending end 11 of the foaming assembly 1, the L-shaped steel wire reinforces the edge of the extending end 11 at the edge of the extending end 11, and the transverse weakening groove 15 reinforces the buffer to a certain extent at the end of the extending end 11 relatively far away from the side pillar of the automobile, and the two cooperate to provide relatively uniform support for passengers at the extending end 11 to the maximum extent, thereby further improving the safety performance and comfort of the automobile seat.

According to the scheme, the depth of the weakened longitudinal groove is changed in the height direction of the seat backrest framework 2, so that the deformation of the foaming assembly 1 is optimized for different parts of a human body when an accident occurs, and the safety performance of the automobile seat is improved.

It should be noted that the longitudinal weakening grooves 14 and the transverse weakening grooves 15 are formed in the foaming assembly 1, and the hardness of the foaming assembly 1 itself has a critical influence on the safety performance of the automobile seat.

As an alternative embodiment, referring to fig. 5, fig. 5 is a schematic diagram illustrating hardness of the foaming assembly according to an embodiment of the present application, the foaming assembly 1 includes a first hardness foam 16 and a second hardness foam 17, wherein the hardness of the first hardness foam 16 is greater than the hardness of the second hardness foam 17. The first rigid foam 16 encloses the second rigid foam 17 in a planar direction parallel to the width direction and the height direction of the seat back frame 2. The surrounding here means that the first hardness foam surrounds the second hardness foam 17 from both sides in the width direction of the seat back frame 2 and three directions above in the height direction of the seat back frame 2.

In addition, in one possible embodiment, the longitudinal weakening grooves 14 can be all positioned on the second hardness foam 17, the first hardness foam 16 positioned on the periphery provides stronger support in the event of an accident, and part of impact force can be borne by the shoulders and other parts of the passenger first, so that certain protection is formed for the waist and the back of the passenger; while the softer second durometer foam 17 cooperates with the longitudinal weakening grooves 14 to enhance cushioning protection of the waist and back. At the same time, the harder first foam is also beneficial to keeping the passenger in a relatively central position of the foaming assembly 1 when an accident happens, so that the possibility that the passenger breaks away from the seat back from the side and collides with other positions of the vehicle cabin is reduced, and the safety performance of the vehicle seat is improved.

For ease of manufacturing, some spacing structure may be provided between the first hardness foam 16 and the second hardness foam 17.

As an alternative embodiment, the foaming assembly 1 is provided with a separating groove (not shown in the figure) for separating the first hardness foam 16 from the second hardness foam 17 when the foaming assembly 1 is manufactured. Specifically, the spacer channel is located on the side of the foam assembly 1 facing away from the seat back frame 2 and between the first hardness foam 16 and the second hardness foam 17. The partition groove is used, the first hardness foam 16 and the second hardness foam 17 can be simultaneously molded and manufactured during production, and additional working procedures such as sewing and the like are not needed to be added for combining the first hardness foam 16 and the second hardness foam 17, so that the production cost of the foaming assembly 1 can be saved. Of course, in other alternative embodiments, the first hardness foam 16 and the second hardness foam 17 may be formed separately and combined by bonding, sewing, etc., which will not be described herein.

The harder first hardness foam 16 can maintain the overall shape of the seat foam assembly 1 during an accident, while the softer second hardness foam 17 can provide better cushioning for the occupant, improving the safety of the seat. And when the passenger sits on the automobile seat during normal running, the first hardness foam 16 provides better supporting strength for the passenger at the shoulder parts and the side wings of the passenger, so that the passenger can keep comfortable sitting posture; while the second durometer foam 17 provides a soft, comfortable seating experience for the lumbar and back of the occupant.

Of course, the foaming assembly 1 may include more foaming portions of different hardness in addition to the above-described two hardness foam combinations.

As an alternative embodiment, the foaming assembly 1 further comprises a third durometer foam 18. With continued reference to fig. 5, the third hardness foam 18 is provided on the side of the second hardness foam 17 facing away from the seat back frame 2, i.e., the third hardness foam 18 is located on the side of the second hardness foam 17 facing toward the occupant. The third hardness foam 18 at least partially covers the second hardness foam 17, and the third hardness foam 18 has a hardness less than the hardness of the second hardness foam 17. Wherein at least partial coverage means that the third hardness foam 18 may completely cover the second hardness foam 17, or may cover only a portion of the second hardness foam 17.

As one example, as in the foaming assembly 1 in fig. 5, the third hardness foam 18 partially covers the second hardness foam 17, and the third hardness foam 18 covers a position where the second hardness foam 17 is relatively biased downward in the height direction of the seat back frame 2. By this arrangement, it is possible to form a vertical double-hardness foam design in the thickness direction of the automobile seat perpendicular to the height direction and width direction of the seatback frame 2, and when the occupant sits down, the second hardness foam 17 provides a certain rigid support for the lumbar back of the occupant, and at the same time, the riding comfort is further enhanced by the third hardness foam 18 having a softer texture.

In the event of an accident, the softer third durometer foam 18 may provide more cushioning to the occupant while the harder second durometer foam 17 may provide a more even stress distribution, reducing the likelihood of greater injury to the occupant due to excessive stress concentrations.

Referring to fig. 6, fig. 6 is a schematic view of a seat cover according to an embodiment of the present application. The car seat in the embodiment of the application also comprises a seat cover 3. The seat cover 3 is coated on the surface of the foaming assembly 1, specifically the surface of the foaming assembly 1 except the surface attached to the seat back skeleton 2. The seat cover 3 is arranged, so that the surface look and feel of the foaming assembly 1 can be improved, and certain functions of moisture absorption, ventilation and the like can be achieved when an occupant sits down.

As an alternative embodiment, with continued reference to fig. 6, in particular with the seat cover 3, in order to bring the foam assembly 1 covered with the seat cover 3 into a full state, the size of the foam assembly 1 is slightly larger than the size of the seat cover 3 when the seat cover 3 is not covered, i.e. the size of the foam assembly 1 has a certain margin with respect to the size of the seat cover 3. Therefore, when the seat cover 3 wraps the foaming assembly 1, certain extrusion is generated on the foaming assembly 1, so that the full state is achieved.

At the sharp corners of the edges of the extended end 11 of the foaming assembly 1, the size of the foaming assembly 1 has a first surplus amount S ₁ with respect to the size of the seat cover 3, at the other edges of the extended end 11 except at the sharp corners, the size of the foaming assembly 1 has a second surplus amount S ₂ with respect to the size of the seat cover 3, and the first surplus amount S ₁ is larger than the second surplus amount S ₂. The foaming material is more easily pressed at the corners of the extending ends 11 due to sitting of passengers, so that the phenomenon that the seat cover 3 floats and the like is generated, and the larger surplus is arranged at the corners of the extending ends 11, so that the foaming assembly 1 is further ensured to have better filling feel under the coverage of the seat cover 3, and the appearance of the automobile seat is further improved.

The embodiment of the application also provides an automobile, which comprises an automobile body and any automobile seat arranged on the automobile body.

According to the technical scheme, the width of the seat back is increased through the foaming assembly extending to the automobile side column, and the riding comfort of the automobile seat is improved; the depth of the weakening groove is changed in the height direction of the seat backrest frame, so that the deformation of the foaming assembly is optimized for different parts of a human body when an accident occurs, and the safety performance of the automobile seat is improved.

The present disclosure is intended to embrace all such alternatives, modifications and variances which fall within the broad scope of the appended claims. Any omissions, modifications, equivalents, improvements, and the like, which are within the spirit and principles of the one or more embodiments of the disclosure, are therefore intended to be included within the scope of the disclosure.

The foregoing is merely illustrative embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think about variations or substitutions within the technical scope of the present application, and the application should be covered. Therefore, the protection scope of the application is subject to the protection scope of the claims.
