Description

[0001] This application claims priority to a Chinese patent application filed on February 14, 2025, with the China National Intellectual Property Administration, application number

[0002] Chinese patent application No. 202520244618.6, filed on February 14, 2025, entitled “Vehicle-mounted mattress”, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0003] The present application relates to a vehicle-mounted mattress. BACKGROUND

[0004] With the improvement of people’s living standards, household cars are becoming increasingly popular. Correspondingly, the interior space of a car, as a relatively closed and private space, is also relatively suitable for users to rest and thus recover their energy. In order to improve the utilization rate of the interior space of a car, more and more car models can put the seat back down, thereby providing a relatively flat load surface through the put-down seat back.

[0005] Although car manufacturers try to improve the comfort of the seat in the usual use state as much as possible to reduce the fatigue of the user during long driving and improve the safety of the vehicle, the situation where the user rests after putting down the seat back has not been fully considered, and the comfort of the user when resting in the vehicle with the seat back put down is not good.

[0006] At present, some vehicle-mounted mattresses have appeared, which can be placed on the put-down seat back, thereby solving the above-mentioned problems to a certain extent. Such a vehicle-mounted mattress is usually a soft cushion, which can improve the comfort of the user to a certain extent on the premise of providing support for the user. However, after the car seat is put down, a flat load surface cannot be formed in the car, and there will still be some depressions. In these depressed positions, the support of the vehicle-mounted mattress to the user is relatively weak, and when the user moves or rests in these positions, the originally flat vehicle-mounted mattress will collapse. Such sudden collapse will affect the comfort of the user. UTILITY MODEL CONTENTS

[0051] The application will be further described below in conjunction with the drawings.

[0052] In the description of the present application, it is to be understood that the orientations or positional relationships indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0053] In addition, the terms "first", "second", and the like are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features referred to. Therefore, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified and limited.

[0054] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "fixing", and the like should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0055] In the present application, unless specifically and explicitly defined otherwise, a first feature is "on" or "under" a second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Also, a first feature is "over", "above" and "on top of" a second feature includes that the first feature is directly above and obliquely above the second feature, or only means that the first feature is horizontally higher than the second feature. A first feature is "under", "below" and "underneath" a second feature includes that the first feature is directly above and obliquely above the second feature, or only means that the first feature is horizontally lower than the second feature.

[0056] In the present application, the meaning of "a plurality of" is two or more, unless specifically and explicitly defined otherwise.

[0057] In order to form a reliable support for the head and neck of the occupant, the headrest of the seat of the vehicle is usually slightly protruding forward relative to the seat back when the seat back is in the upright normal use state; after the seat is reclined, the headrest inevitably sinks relative to the rear surface of the seat back. If the user places the vehicle mattress in the sinking position, when the user moves or rests in the position of the headrest, the corresponding part of the vehicle mattress will also collapse.

[0058] With reference to Figure 1 The present application provides a vehicle mattress 100 placed on the backrest 310 of the rear seat 300 of the vehicle to solve the problem of collapse of the vehicle mattress in the position of the headrest of the vehicle. The upper surface 111 of the vehicle mattress 100 is used to support the user, for the user to move or rest thereon. The backrest 310 is reclined and supported by the seat cushion 330. In the illustrated orientation, the left side is the rear side of the vehicle, and the right side is the front side of the vehicle. Accordingly, the backrest 310 is reclined forward. In this embodiment and subsequent embodiments, the side that contacts the backrest 310 and the seat cushion 330 is referred to as the front side 3101 of the backrest 310 (corresponding to the side of the backrest of the front seat 300' that is used to support the back of the user, which is on the right side in the figure), and the other side is referred to as the back side 3103 of the backrest 310. Then a part of the vehicle mattress 100 is above the back side 3103 of the backrest 310 and is supported thereby.

[0059] The rear of the rear seat 300 is the trunk 500 of the vehicle. After the backrest 310 is reclined, the back side 3103 and the trunk 500 usually abut each other (are parallel, or form a small angle), so that the left side of the vehicle mattress 100 in the illustrated orientation is supported by the trunk 500. Understandably, in some embodiments, the seat backrest 310 provides support for the vehicle mattress 100, but the trunk 500 does not provide support for the vehicle mattress 100.

[0060] As mentioned above, the seat headrest 311 is generally slightly forward of the seat back 310. After the seat 300 is laid down, the seat headrest 311 forms a sunken space, i.e. the headrest 311 cannot provide a stable support for the vehicle mattress 100. In the case that the vehicle mattress 100 cannot be stably supported at the position of the headrest 311, the vehicle mattress 100 cannot provide support for the user at the position of the headrest 311 either. Thus, the position is severely sunken when the user is active at the position, resulting in a poor user experience.

[0061] As shown in Figs. 13A and 13B, the vehicle mattress 100 further comprises a headrest support portion 130. The headrest support portion 130 is disposed at the underside of the vehicle mattress 100, and the headrest support portion 130 is located diagonally above the headrest 311 and in contact with the headrest 311. Understandably, the headrest support portion 130 can also be located directly above the headrest 311 in alternative embodiments. Figure 1 Figure 2 In other words, the headrest support portion 130 is located above the headrest 311, and the headrest 311 provides a stable support for the vehicle mattress 100 by supporting the headrest support portion 130. In this way, the vehicle mattress 100 does not significantly sink when the user is active or resting at the position corresponding to the headrest 311, and the user experience is greatly improved.

[0062] Referring to Figs. 14A and 14B, the plane in which the position of the outer surface of the headrest support portion 130 in contact with the headrest 311 is defined as face a. The lower surface of the vehicle mattress 100 is partially rested on the back surface 3103 of the seat 310 (this part can be referred to as a seat support portion). The plane in which the seat support portion is located is defined as face b. Then, the included angle between face a and face b is not greater than 45° (for example, it can be 45°, 30°, 25°, 15° or 0°, but is not limited thereto). Thus, the vertical component of the force exerted by the headrest 311 on the headrest support portion 130 will not be less than the horizontal component (assuming that the vehicle mattress 100 is ideally placed horizontally). In this way, the force exerted by the headrest 311 on the headrest support portion 130 can reliably support the vehicle mattress 100.

[0063] Referring to Figs. 14A and 14B, the plane in which the position of the outer surface of the headrest support portion 130 in contact with the headrest 311 is defined as face a. The lower surface of the vehicle mattress 100 is partially rested on the back surface 3103 of the seat 310 (this part can be referred to as a seat support portion). The plane in which the seat support portion is located is defined as face b. Then, the included angle between face a and face b is not greater than 45° (for example, it can be 45°, 30°, 25°, 15° or 0°, but is not limited thereto). Thus, the vertical component of the force exerted by the headrest 311 on the headrest support portion 130 will not be less than the horizontal component (assuming that the vehicle mattress 100 is ideally placed horizontally). In this way, the force exerted by the headrest 311 on the headrest support portion 130 can reliably support the vehicle mattress 100. Figure 2

[0064] It will be understood by those skilled in the art that, although the seat back 310 in Figs. 13A and 13B is laid forward, so that the vehicle mattress 100 is placed on the back surface 3103 of the seat back 310. However, in some cases, the seat back 310 of the vehicle can also be laid backward, and the vehicle mattress 100 is correspondingly placed on the front surface 3101 of the seat back 310. Figure 1 It will also be understood by those skilled in the art that the seat 300 can also be a middle-row or front-row seat of the vehicle in some embodiments.

[0065]

[0066] ​​​The headrest support portion 130 can be integrally formed at the bottom of the vehicle mattress 100, or can be separately manufactured and then connected to the bottom of the vehicle mattress 100.

[0067] Still referring to Figure 2 In some exemplary embodiments, the headrest support portion 130 is separately manufactured and then connected to the bottom of the vehicle mattress 100. In this case, the vehicle mattress 100 includes the vehicle mattress body 110 and the headrest support 130a. The upper portion (upper surface) of the vehicle mattress body 110 is used to support a user, constituting the upper surface 111 of the vehicle mattress 100; the headrest support 130a is connected to the bottom of the vehicle mattress body 110 by the connector 150, thereby forming the headrest support portion 130.

[0068] Referring to Figure 3 and Figure 4 The connector 150 is a gas chamber connecting assembly 150. Accordingly, the vehicle mattress body 110 and the headrest support 130a are inflated, and the gas chambers of the two are connected by the connector 150. Among them, Figure 3 Fig. 4 shows the case where the vehicle mattress body 110 and the headrest support 130a are connected together by the gas chamber connecting assembly 150, Figure 4 Fig. 5 shows the case where the vehicle mattress body 110 and the headrest support 130a are not connected.

[0069] In the description of the present application, the "inflatable" product (or "inflatable product") contains at least one inflation chamber for inflation. After the pressure of the gas (for example, air) in the inflation chamber reaches the required value, the inflatable product is in an inflated state and maintains a certain shape. After the gas in the inflation chamber of the inflatable product is discharged, the inflatable product is in a deflated state, and the volume of the inflatable product is greatly reduced relative to when it is in an inflated state, thereby facilitating the storage of the inflatable product. One or more tensioning members are provided in the inflation chamber of the inflatable product, and at least two ends of the tensioning member are respectively connected to the wall of the inflation chamber. The tensioning member is tensioned to provide a pulling force to limit the deformation of the wall of the inflation chamber, so that the inflatable product can maintain a certain shape after being inflated. For example, referring to Figure 2 The inside of the headrest support 130a is provided with a plurality of tensioning members 131.

[0070] Referring to Figure 4 The gas chamber connecting assembly 150 includes a female head 151 and a male head 153, which are interference fit. The female head 151 is provided with a through passage 1511, and the male head 153 is provided with a through passage 1531, which forms a passage between the internal gas chambers of the vehicle mattress body 110 and the headrest support 130a.

[0071] In the illustrated embodiment, the female head 151 is mounted on the vehicle mattress body 110, and the male head 153 is mounted on the headrest support 130a. It is understood that the mounting positions of the female head 151 and the male head 153 can be interchanged in other embodiments.

[0072] It is understood that the dimensional relationships of the vehicle mattress body 110, the headrest support 130a, and the air chamber connecting assembly 150 are adjusted for the purpose of clearly describing the structure and working manner of the air chamber connecting assembly 150. Figure 3 and Figure 4 The dimensional relationships of the middle parts do not represent their actual dimensional relationships.

[0073] In addition, the above-mentioned passages 1511 and 1531 do not exist in some other embodiments. In this case, the female head 151 and the male head 153 are combined as a plug-in assembly to connect the vehicle mattress body 110 and the headrest support 130a. In this case, the vehicle mattress body 110 and the headrest support 130a can be inflatable or non-inflatable, respectively. If the vehicle mattress body 110 is non-inflatable, the vehicle mattress body 110 includes an outer cover (for example, but not limited to, made of fabric or polymer film) and an elastic filler (for example, but not limited to, sponge or silk) filled in the outer cover. If the vehicle mattress body 110 and the headrest support 130a are inflatable, respectively, they need to be respectively provided with air valves for inflation.

[0074] With reference to Figure 1 , Figure 5 and Figure 6 , the headrest support 130a can have different shapes and configurations in different embodiments. For example, but not limited to, the headrest support 130a can have Figure 1 or Figure 5 a cross-sectional shape substantially in the shape of a triangle (in different embodiments, it can be a right triangle / acute triangle / obtuse triangle, isosceles triangle / non-isosceles triangle, or other shapes of triangle), or have Figure 6 a cross-sectional shape substantially in the shape of a quadrilateral / rectangle. For another example, but not limited to, with reference to Figure 1 , the male head 153 (or the female head 151, or the air chamber connecting assembly 150, or the plug-in assembly) is arranged in the center (or near the center, for example, the distance from the central axis of the headrest support 130a is not greater than 30% of the width of the headrest support 130a) of the headrest support 130a in some embodiments, so that the headrest support 130a is more stably fixed at the bottom of the vehicle mattress body 110 and unnecessary rotation is avoided; while in some other embodiments, with reference to Figure 5The male head 153 (or the female head 151, or the air chamber connecting assembly 150, or the plug-in assembly) is arranged near the edge of the headrest support 130a (for example, the distance from the central axis of the headrest support 130a is not less than 30% of the width of the headrest support 130a), thereby saving the space required for installing the headrest support 130a, which is more advantageous for vehicles with small interior space.

[0075] It can be understood that the above-mentioned connecting member can also be replaced by other connecting members in other embodiments, such as one or more of a zipper, a magic buckle, a buckle, and a plug-in buckle.

[0076] Reference Figure 7 In some embodiments, the headrest support 130 has the same or substantially the same shape as described above and is in the same or substantially the same position as described above. The difference is that the headrest support 130 is integrally formed on the bottom of the vehicle mattress 100. For example, the vehicle mattress 100 is inflatable, and the tensioning member inside it forms the required shape when it is inflated; for another example, the vehicle mattress 100 is non-inflatable, including an outer cover (for example, but not limited to, made of fabric or polymer film) and an elastic filler (for example, but not limited to, sponge or silk) filled in the outer cover.

[0077] The above describes in detail the structure of the vehicle mattress with a headrest support and the headrest support thereof, as well as the working principle of the headrest support. In addition to the headrest position, the vehicle mattress 100 can also be concave at other positions due to lack of support. For example, after the seat backrest 310 is folded down, the armrests on both sides of the seat 300 can be lower than the back surface 3103 of the seat backrest 310, thereby being unable to provide sufficient support for the vehicle mattress 100 placed above them, similar to the headrest 311, so that the vehicle mattress 100 collapses when the user moves or rests in this position.

[0078] To solve this problem, in some embodiments, the vehicle mattress 100 is provided with a lower support for supporting by some components in the vehicle that are suitable for bearing weight (hereinafter referred to as support devices). It can be understood that the headrest 311 also belongs to the support devices. The structure, working principle, and effects of the lower support(s) are the same or substantially the same as those of the headrest support 130 described above. For example, but not limited to:

[0079] 1) The lower support is formed on the bottom of the vehicle mattress 100, which can be integrally formed on the bottom of the vehicle mattress 100 or separately installed;

[0080] 2) The lower support can be inflatable or non-inflatable;

[0081] 3) The lower support is optionally connected to the vehicle mattress body 110 by the above-mentioned connecting member;

[0082] 4) The plane in which the surface of the lower support portion for contacting the support device lies and the plane in which the seat support portion lies form an angle of not more than 45°;

[0083] 5) The lower support portion can have a cross section that is substantially triangular, quadrangular / rectangular or of another shape.

[0084] Figure 8 And Figure 9 The case where the support device is an armrest of a vehicle seat is shown. In this example, two seats are juxtaposed, and two armrests that are away from each other are respectively outer armrests 351, and two armrests that are close to each other are respectively inner armrests 353. Among them, the lower support portion includes two outer armrest support portions 171 and one inner armrest support portion 173, which are respectively located directly above (or obliquely above in other embodiments) the outer armrests 351 and the inner armrests 353. Among them, when the lower support portion (for example, the outer armrest support portion 171) is inflatable, the tensioning member inside the lower support portion (for example, the inner tensioning member 1711 of the outer armrest support portion 171) causes the lower support portion to form the required shape when it is inflated. These armrest support portions enable the vehicle mattress 100 to remain stable when the user lying down turns over to the left and right, avoiding the user from rolling over or shaking.

[0085] Figure 10 The case where the support device is an armrest box 355 (for example, an armrest box between front seats, a central armrest box, or a rear armrest box) of a vehicle is shown. The armrest box support portion 175 fills the height difference between the armrest box 355 and the back of the seat back and forms sufficient support, fills the potential unevenness of the back of the seat back 310, and / or provides more elastic support to the user to improve comfort. Avoiding the vehicle mattress 100 from collapsing when the user is active or resting in this position. Among them, if there are control devices (such as knobs, buttons, etc.) on the armrest box 355, the armrest box support portion 175 should avoid them.

[0086] In addition, the vehicle mattress 100 can not contain the headrest support portion 130 in some embodiments, but has other lower support portions for supporting the vehicle mattress 100.

[0087] For the sake of brevity, other details of the lower support portion that are the same as or substantially the same as the headrest support portion are not described again.

[0088] Among them, if the lower support portion is an armrest box support portion or an armrest support portion, the lower support portion can be a separate support piece and placed manually by the user on the armrest box or armrest of the vehicle when needed.

[0089] It will be obvious to a person skilled in the art that the application is not limited to the details of the above-described exemplary embodiments but can be implemented in other embodiments without departing from the scope of the application. The application is therefore not limited by the described examples but can vary within the scope of the claims and their equivalents. No reference signs in the claims should be considered as limiting the scope of the claims. Furthermore, it is obvious that the wording "comprising" does not exclude other parts and does not exclude other steps. Singular references do not exclude a plurality. Multiple units or devices stated in a device claim can also be implemented by one unit or device, either by software or hardware. The terms first, second and the like do not denote any ordering, but rather serve as names.
