Description

Technical Field

[0001] This application pertains to vehicle-mounted mattresses. Background Technology

[0002] To improve the convenience of users resting in their family cars, more and more models can fold down the seat backs, thus providing a more spacious interior.

[0003] Car mattresses are now available that can be placed inside a vehicle, providing a large, flat resting platform for users when the seat back is reclined. These car mattresses are typically soft pads that can enhance user comfort to some extent while providing support.

[0004] However, the interior space of a car is originally designed for driving and riding. When the seats are folded down, the interior space will form several block-shaped areas that are not of equal height, and these block-shaped areas may themselves be uneven. As a result, when a car mattress is placed on these block-shaped areas, the upper surface supporting the user will also be uneven or will give the user a feeling of "discontinuity", resulting in poor comfort.

[0060] The same or similar reference numerals in the accompanying drawings represent the same or similar parts. Detailed Implementation

[0061] The present application will now be described in further detail with reference to the accompanying drawings.

[0062] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0063] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0064] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0065] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0066] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0067] In the description of this application, the "inflatable" product (or "inflatable product") includes at least one inflation chamber. When the pressure of the gas (e.g., air) within the inflation chamber reaches a desired value, the inflatable product is inflated and maintains a certain shape. When the gas in the inflation chamber is expelled, the inflatable product is deflated, and its volume is significantly reduced compared to its inflated state, thus facilitating storage. One or more tensioning members are provided within the inflation chamber of the inflatable product, with at least two ends connected to the wall of the inflation chamber. When tensioned, the tensioning members provide tensile force to limit deformation of the walls of the inflation chamber, allowing the inflatable product to maintain a certain shape after inflation.

[0068] refer to Figure 1 and Figure 2 This application provides a vehicle-mounted mattress 10. The vehicle in which the mattress 10 is placed has two (or more) rows of seats, including the driver's seat and front passenger seat (first row of seats). Figure 2 In the illustrated configuration, the backrests of the driver's seat and the front passenger seat are folded back without restriction; in other embodiments, the first-row seats may also be folded forward. The vehicle mattress 10 includes a main body 100 and a support assembly 300. In normal use, the support assembly 300 is located below the main body 100 and supports the main body 100. The support assembly 300 further includes a first support portion 310, a second support portion 330, and a third support portion 350. The first support portion 310 and the third support portion 350 are located at the front of the vehicle mattress 10 (corresponding to the front side of the vehicle, as indicated by arrow F in the figure), and the second support portion 330 is located at the rear of the vehicle mattress (corresponding to the rear side of the vehicle, as indicated by arrow R in the figure).

[0069] The first support portion 310 is placed on the seat cushion 211 and backrest 213 of the passenger seat 210, and the second support portion 330 is placed on the seat cushion 233 of the second-row seats 230 of the vehicle. The first support portion 310 and the second support portion 330 are integrally formed. The third support portion 350 is placed on the seat cushion and backrest of the driver's seat and is separate from the second support portion 330, rather than integrally formed. It is understood that in other embodiments, the first support portion 310 may also be placed on the seat cushion and backrest of the driver's seat, while the second support portion 330 remains placed on the seat cushion 233 of the second-row seats 230 of the vehicle. The first support portion 310 and the second support portion 330 are still integrally formed. The third support portion 350 is placed on the seat cushion and backrest of the passenger seat and is separate from the second support portion 330, rather than integrally formed. It is also understood that in other embodiments, the third support portion may be connected to the second support portion, while the first and second support portions are separate.

[0070] Two or more integrally formed support portions may have a connecting surface that smoothly connects to their respective outer contours, or may be made of a single sheet / block of material, thereby forming a single unit. In some embodiments, the integrally formed support portions may optionally be inflatable, with their air chambers interconnected, so that two or more integrally formed support portions can be inflated simultaneously through a single air valve, and their internal air pressure is the same, providing more stable support.

[0071] It is understandable that the first support 310 may be placed only on the backrest 213 of the passenger seat 210, and not simultaneously on the seat cushion of the passenger seat 210. Additionally, Figure 2 The first row of seats shown is folded backwards. In other embodiments, the first row of seats can also be folded forwards; in this case, optionally, the first support 310 is placed on the backrest 213 of the passenger seat 210. Furthermore, the vehicle seats in this application can all be folded forwards or backwards, and the situation shown in the accompanying drawings does not constitute a limitation on the usage of the vehicle mattress in this application.

[0072] For ease of description, the component located behind the first-row seats in the vehicle that supports the in-vehicle mattress is collectively referred to as the rear support unit. For example, the rear support unit can be (but is not limited to) one or more of the following: the backrest and cushion of the seat behind the driver's seat, or the vehicle's trunk floor (e.g., the rear seats may be folded forward or backward). In this example, the rear support unit includes the cushion 231 of the second-row seat 230. In other embodiments, the rear support unit may also include the backrest / cushion of the third-row (or even fourth- or fifth-row) seats of the vehicle.

[0073] Still referencing Figure 1In some embodiments, the first support portion 310 and / or the third support portion 350 cannot be made very wide due to the width of the driver's seat or the front passenger seat itself. To effectively utilize space, when the rear load-bearing unit includes the seat cushion, the second support portion 330 can extend along the entire width (or almost the entire width) of that row of seats. The first support portion 310 and the second support portion 330 are integrally formed, thereby jointly supporting the main body 100 to form a stable and continuous support. Thus, the first support portion 310 and the second support portion 330 are arranged in an L-shape. The front-rear position of the third support portion 350 is the same as that of the first support portion 310. Therefore, the first support portion 310, the second support portion 330, and the third support portion 350 are arranged in a U-shape. As can be understood, as described above, in some embodiments, the first support portion 310 is placed on the seat cushion 211 and backrest 213 of the passenger seat 210, the second support portion 330 is placed on the seat cushion 233 of the second-row seat 230 of the vehicle, the first support portion 310 and the second support portion 330 are integrally formed, and the third support portion 350 is placed on the seat cushion and backrest of the driver's seat, and is separate from the second support portion 330, rather than integrally formed; in other embodiments, the first support portion 310 may also be placed on the seat cushion and backrest of the driver's seat, the second support portion 330 is still placed on the seat cushion 233 of the second-row seat 230 of the vehicle, the first support portion 310 and the second support portion 330 are still integrally formed, and the third support portion 350 is placed on the seat cushion and backrest of the passenger seat, and is separate from the second support portion 330, rather than integrally formed. In a more ideal state, the width of the second support portion 330 is greater than the sum of the widths of the first support portion 310 and the third support portion 350. In other words, when the widths of the first support portion 310 and the third support portion 350 are equivalent, the width of the second support portion 330 will be more than twice the width of each of the first support portion 310 and the third support portion 350.

[0074] While separating the first support portion 310 and the second support portion 330 can achieve support for the main body 100, the gap between them means that if the user moves or turns over on the main body, both portions will shift and deform, failing to work together to support the main body 100 and causing discomfort such as swaying, rocking, and tilting. Making the first support portion 310 and the second support portion 330 a single unit effectively solves this problem.

[0075] In some embodiments, the support component 300 is connected to the main body 100 via a connector.

[0076] For example, refer to Figure 3 and Figure 4The connector is the air chamber connection assembly 130. Accordingly, the main body 100 and the support assembly 300 of the vehicle mattress are both inflated, and their air chambers are connected via the connector 130. Figure 3 The diagram shows the main body 100 and the support assembly 300 (taking the first support part 310 connected to the main body 100 as an example) being connected together by the air chamber connection assembly 130. Figure 4 This indicates the case where the two are not connected.

[0077] The air chamber connection assembly 130 includes a female connector 131 and a male connector 133, which are interference-fitted (optionally, but not limited to, by means of a sealing element such as a rubber ring disposed on the outer side of the male connector 133) to provide good airtightness and prevent air leakage at the connection between the vehicle mattress body 100 and the support assembly 300. The female connector 131 has a through channel 1311, and the male connector 133 has a through channel 1331. Once connected, the female connector 131 and the male connector 133 are non-removable, and the two channels inside them form channels between the internal air chambers of their body 100 and the support assembly 300.

[0078] In the illustrated embodiment, the female connector 131 is mounted on the vehicle mattress body 100, while the male connector 133 is mounted on the support assembly 300. It is understood that in other embodiments, the mounting positions of the female connector 131 and the male connector 133 may be interchanged.

[0079] It should be understood that the dimensional relationships of the various components of the vehicle mattress have been adjusted in order to clearly describe the structure and operation of the air chamber connection assembly 130. Figure 3 and Figure 4 The dimensional relationships of the components do not represent their actual dimensional relationships.

[0080] Furthermore, in some embodiments, the aforementioned channels 1311 and 1331 are absent, meaning that both the female connector 131 and the male connector 133 are airtight. In this case, the female connector 131 and the male connector 133 are combined as a plug-in assembly (without airflow channels) to connect the main body 100 and the support assembly 300. In this case, the main body 100 and the support assembly 300 can be either inflatable or non-inflatable. If the main body 100 is non-inflatable, the main body 100 includes an outer cover (e.g., but not limited to, made of fabric or a polymer film) and an elastic filler (e.g., but not limited to, sponge or silk) filled in the outer cover.

[0081] Understandably, the above-mentioned connectors can be replaced with other connectors in other embodiments, such as one or more of zippers, Velcro, buckles, and snap fasteners.

[0082] refer to Figure 5Optionally, based on the above embodiments, the first support portion 310 and the second support portion 330 are integrally formed, and the third support portion 350 and the second support portion 330 are also integrally formed, so as to solve the problem of discomfort such as shaking, swaying and tilting that may occur when the user is in the connection position of the third support portion 350 and the second support portion 330.

[0083] refer to Figure 6 and Figure 7 Optionally, the support assembly 300 further includes a fourth support portion 370. The fourth support portion 370 is disposed rearward and adjacent to the second support portion 330, and is positioned on the vehicle's trunk floor 250. Non-limitingly, the vehicle has a second-row seat 230 with its backrest 233 folded forward. The second support portion 330 rests on the backrest 233. The trunk floor 250 is directly adjacent to the rearward side of the second-row seat 230, and the second support portion 330 and the fourth support portion 370 are integrally formed, thereby providing continuous and stable support at the connection point between the trunk floor 250 and the second-row seat 230.

[0084] refer to Figure 8 It is understood that although the first support 310 shown above is placed on both the seat cushion 211 and the backrest 213 of the passenger seat 210, in other embodiments, the first support 310 may be placed only on the backrest 213.

[0085] refer to Figure 9 In some embodiments, the vehicle also has a third row of seats 270 in addition to the aforementioned second row of seats 230. Figure 7 The illustrated embodiment differs in that the support assembly does not include the fourth support portion 370, but has a fifth support portion 390. The fifth support portion 390 is placed on the third-row seat 270 of the vehicle, and the second support portion 330 and the fifth support portion 390 are integrally formed, thereby providing continuous and stable support at the connection position between the third-row seat 270 and the second-row seat 230.

[0086] Based on this, refer to Figure 10 The rear side of the third-row seats 270 is adjacent to the vehicle's trunk floor 250. At this time, the support assembly 300 also includes a fourth support 370. The fourth support 370 is placed on the trunk floor 250, and a fifth support 390 is located between the fourth support 370 and the second support 330, positioned on the folded-down backrest of the third-row seats 270. The fifth support 390 is integrally formed with the second support 330 and the fourth support 370, thereby providing continuous and stable support at the connection points between the third-row seats 270 and the second-row seats 230, and at the connection points between the third-row seats 270 and the trunk floor 250.

[0087] refer to Figures 1 to 10 In the above embodiments, optionally, the first support portion 310 and the third support portion 350 are spaced apart in the width direction, thereby forming a support interval 150. The first row of seats in a vehicle typically contains operating devices such as gear levers and various knobs, or storage devices such as cup holders and storage compartments. The support interval 150 provides space for these devices, preventing interference that could lead to misoperation or inconvenience. Based on this, for example, referring to... Figure 1 The main body 100 has a notch at the position of the support interval 150. The notch and the support interval 150 allow the vehicle mattress 10 to pass through vertically, thereby leaving more space for the aforementioned operation / storage device and making it easier for users to use the device.

[0088] Understandably, refer to Figure 11 In some embodiments, the aforementioned notch may be omitted, thereby giving the body 100 of the vehicle mattress 10 a relatively more complete and flat surface.

[0089] Furthermore, to ensure the car mattress 10 can be placed more securely inside the vehicle, the support assembly 300 may optionally have multiple thickness peaks. These thickness peaks not only effectively fill irregular gaps between the main body 100 and the vehicle seats, trunk, etc., but also horizontally hold these gaps in place, making full use of the uneven terrain inside the vehicle.

[0090] Referring to the accompanying drawings, a thickness peak refers to a location where the thickness of the support component 300 is greater than the thickness of its adjacent two sides. For example, see reference... Figure 2 and Figure 7 The support component 300 includes a first thickness peak 320, a second thickness peak 340, and a third thickness peak 360. The first thickness peak 320 and the second thickness peak 340 are disposed on the first support portion 310 and / or the third support portion 350. For example, see reference... Figure 9 The support assembly 300 includes a first thickness peak 320, a second thickness peak 340, a third thickness peak 360, and a fourth thickness peak 380. The first thickness peak 320 and the second thickness peak 340 are disposed on the first support portion 310, the third thickness peak 360 is disposed on the second support portion 330, and the fourth thickness peak is disposed on the fifth support portion 390. It is understood that one of the first thickness peak 320 and the second thickness peak 340 may be omitted. Alternatively, the second thickness peak may be disposed on the second support portion 330. Or, all thickness peaks may be disposed on the first support portion 310. It is also understood that the support assembly 300 may have five, six, or more thickness peaks.
