Description

Technical Field

[0001] This utility model relates to the field of furniture, specifically to a chair. Background Technology

[0002] Current car seats typically lack anti-tipping features, especially child seats. Children can easily tip over or even get injured if they rock back and forth in the seat. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a seat that can reduce the chance of the seat tipping over and improve the safety of product use.

[0004] One embodiment of the present invention provides a seat, which includes a seat body and a plurality of legs supporting the seat body. The seat also includes an airbag assembly and an inflation device connected to it. The inflation device is used to inflate the airbag assembly. The airbag assembly includes: at least one safety airbag disposed on the seat body for inflating and deploying to surround a user sitting on the seat body; and / or a plurality of telescopic airbags connected one-to-one with the plurality of legs. The telescopic airbags are used to inflate and deploy to lift the corresponding legs upward, thereby maintaining the balance of the seat body.

[0005] The seat provided in this embodiment features telescopic airbags on its outriggers. When these airbags inflate and deploy, they lift the corresponding outriggers upwards. This allows the airbags to inflate when the seat tilts, and by adjusting the outrigger height, the seat maintains its balance, preventing further tilting and improving safety. Furthermore, by incorporating airbags into the seat, they inflate and deploy to surround the user, effectively protecting them from injury after the seat tilts.

[0006] In this embodiment, when the airbag assembly includes both a safety airbag and a retractable airbag, the retractable airbag can not only prevent the seat body from tilting, but the safety airbag can also protect the user when the seat body tilts, resulting in good protection.

[0007] Furthermore, in some embodiments, each support leg includes a first support leg segment and a second support leg segment connected vertically. The upper end of the telescopic airbag is connected to the first support leg segment, and the lower end of the telescopic airbag is connected to the second support leg segment. The telescopic airbag inflates and deploys to lift the first support leg segment upwards. This design facilitates adjusting the overall length of the support leg after the telescopic airbag inflates and deploys, thereby adjusting the tilt posture of the seat body.

[0008] Furthermore, in some embodiments, the telescopic airbag is disposed inside the outrigger, with the lower end of the first outrigger segment and the upper end of the second outrigger segment nested together. This concealed design of the telescopic airbag not only improves aesthetics but also ensures that the deployment of the airbag is limited by the first and second outrigger segments, thus facilitating accurate extension and retraction of the airbag along the length of the outrigger.

[0009] Furthermore, in some embodiments, the telescopic airbag is located at the bottom of the outrigger. This facilitates airbag installation, and the outrigger can be a single, integrated structure, eliminating the need for segmented design and resulting in high structural strength.

[0010] Furthermore, in some embodiments, at least one airbag is located in the upper part of the seat body to inflate and enclose the user's head. This protects the head, a vital area of ​​the body, and can prevent serious injury to the user.

[0011] Furthermore, in some embodiments, the airbag is embedded in the top of the seat body. This facilitates airbag protection for the user's head. Moreover, embedding the airbag in the seat body does not affect the user's movement space and improves aesthetics. Of course, when the airbag inflates and deploys, it protrudes from the seat body to protect the user.

[0012] Furthermore, in some embodiments, both ends of the seat body in the width direction have forward-extending limiting walls, and the airbag is positioned in front of the two limiting walls. This way, when the airbag deploys, it will not directly impact the user on the seat body, reducing the risk of accidental injury and improving the user experience.

[0013] Furthermore, in some embodiments, the seat further includes: a detection device for detecting the tilt direction and tilt amplitude of the seat body; and a control module connected to the detection device and the inflation device for sending an airbag inflation signal or a telescopic airbag inflation signal to the inflation device based on the detection results of the detection device. This design facilitates timely detection of the tilt of the seat body and timely control of the telescopic airbag or safety airbag inflation, ensuring product safety.

[0014] Furthermore, in some embodiments, the seat also includes a buzzer and / or a warning light, electrically connected to the control module. The control module can also send an alarm signal to the buzzer and / or an illumination signal to the warning light based on the detection results of the detection device. This facilitates alerting others that the seat has tilted or fallen over, improving product safety.

[0015] Furthermore, in some embodiments, the seat also includes a tray connected to the seat body. The tray contains a heating element and a temperature sensing module. The heating element heats the tray, and the temperature sensing module detects the temperature of the tray. Thus, the seat can be used as a dining chair, and the heating of the tray allows for the heating of food placed on it, which helps maintain food temperature and improves the user experience.

[0016] Furthermore, in some embodiments, the plate also includes an indicator light disposed within the plate to illuminate when the heating element is heating, thereby reducing the likelihood of burns to the user. Additionally, it provides a convenient way for the user to turn off the heating function when heating is no longer needed.

[0017] Furthermore, in some embodiments, the seat also includes a battery or power module connected to the inflation device for supplying power to the inflation device. This allows power to be provided for inflating the inflation device.

[0018] Other aspects and / or advantages of the present invention will be set forth in part in the description which follows, and in part will be clear from the description or may be learned by practice of the present invention. Attached Figure Description

[0035] The following will combine Figures 1 to 5 The present invention describes a seat provided by an embodiment of the present invention.

[0036] like Figures 1 to 4 As shown, one embodiment of the present invention provides a seat, which includes a seat body 110 and a plurality of support legs 120 supporting the seat body 110. The seat also includes an airbag assembly 140 and an inflation device 150 connected to each other. The inflation device 150 is used to inflate the airbag assembly 140. The airbag assembly 140 includes: at least one safety airbag 141 disposed on the seat body 110 for inflating and deploying to surround a user sitting on the seat body; and / or a plurality of telescopic airbags 142, which are connected one-to-one with the plurality of support legs 120. The telescopic airbags 142 are used to inflate and deploy to lift the corresponding support legs 120 upward, thereby maintaining the balance of the seat body 110.

[0037] The seat provided in this embodiment features a telescopic airbag 142 on the support leg 120. When the airbag 142 inflates and deploys, it can lift the corresponding support leg 120 upwards. Therefore, when the seat body 110 tilts, the airbag 142 can be inflated using the inflation device 150. By adjusting the height of the support leg 120, the seat body 110 can be kept balanced, preventing further tilting and improving the seat's safety. Furthermore, by providing a safety airbag 141 on the seat body 110, the airbag 141 can inflate when the seat tilts, deploying to surround the user and protect them, effectively preventing injury after the seat tilts.

[0038] In this embodiment, when the airbag assembly 140 includes both a safety airbag 141 and a telescopic airbag 142, not only can the telescopic airbag 142 prevent the seat body 110 from tilting, but the safety airbag 141 can also protect the user when the seat body 110 tilts, resulting in good protection.

[0039] Regarding the specific location of the telescopic airbag 142, in some embodiments, such as Figure 2 and Figure 3 As shown, each support leg 120 includes a first support leg 121 and a second support leg 122 connected vertically. The upper end of the telescopic airbag 142 is connected to the first support leg 121, and the lower end of the telescopic airbag 142 is connected to the second support leg 122. The telescopic airbag 142 inflates and deploys to lift the first support leg 121 upwards. This design facilitates adjusting the overall length of the support leg 120 after the telescopic airbag 142 inflates and deploys, thereby adjusting the tilt posture of the seat body 110.

[0040] Furthermore, such as Figure 2 and Figure 3 As shown, the telescopic airbag 142 is disposed inside the outrigger 120, with the lower end of the first outrigger 121 and the upper end of the second outrigger 122 nested together. This concealed design of the telescopic airbag 142 not only improves aesthetics but also ensures that the deployment of the airbag 142 is limited by the first and second outriggers, thus facilitating accurate extension and retraction of the airbag 142 along the length of the outrigger 120.

[0041] Furthermore, when the telescopic airbag 142 is extended to its maximum length, the first section of the support leg 121 and the second section of the support leg 122 maintain a nested relationship, so that the telescopic airbag 142 will not be exposed during the overall length of the support leg 120, resulting in a good appearance.

[0042] Furthermore, the lower part of the first outrigger 121 has an upper baffle, and the upper part of the second outrigger 122 has a lower baffle. The two ends of the telescopic airbag 142 are connected to the upper baffle and the lower baffle, respectively, so that the telescopic airbag 142 can lift the first outrigger 121 by lifting the upper baffle.

[0043] Of course, in other embodiments, the telescopic airbag 142 may also be partially exposed outside the outrigger 120.

[0044] Furthermore, in some other embodiments, the telescopic airbag 142 is disposed at the bottom of the outrigger 120. This makes the telescopic airbag 142 easy to install, and the outrigger 120 can be a one-piece structure, eliminating the need for segmented design and resulting in high structural strength.

[0045] Regarding the specific location of the airbag 141, in some embodiments, such as Figure 2 As shown, at least one airbag 141 is located on the upper part of the seat body 110, for inflating and deploying to wrap around the user's head. This protects the vital area of ​​the head and prevents serious injury to the user.

[0046] Furthermore, such as Figure 2 As shown, the airbag 141 is embedded in the top of the seat body 110; and / or the airbag 141 is embedded in both ends of the seat body 110 in the width direction. In this way, the airbag 141 can provide multi-directional protection for the user from above and / or from both sides, resulting in good protective effect. Furthermore, embedding the airbag 141 in the seat body 110 does not affect the user's movement space within the seat body 110, and it has a good aesthetic appearance. Of course, when the airbag 141 inflates and deploys, it will protrude from the seat body 110 to protect the user.

[0047] In a specific embodiment, such as Figure 2 As shown, there are three airbags 141. Both ends of the seat body 110 in the width direction have forward-extending limiting walls 111. Two airbags 141 are respectively positioned in front of one limiting wall 111, and the third airbag 141 is positioned at the top of the seat body 110. This way, when the airbags 141 deploy, the two side airbags 141 will not directly impact the user on the seat body 110, reducing the risk of accidental injury and improving the user experience.

[0048] Specifically, the airbag 141 can be positioned on the upper part of the limiting wall 111, close to the user's head, thus facilitating head protection. Of course, in other embodiments, the airbag 141 can further surround the user's shoulders or even arms, not just the head. The larger the protective area of ​​the airbag 141, the more comprehensive the protection. Naturally, considering the inflation speed of the inflation device 150, priority can also be given to protecting the user's head and other vital areas.

[0049] Regarding the control method of the airbag assembly 140, in some embodiments, corresponding control buttons can be configured on the seat body 110, such as the telescopic airbag inflation / deflation button and the safety airbag inflation / deflation button. After the user presses the corresponding button, the inflation device 150 is triggered to inflate or deflate the corresponding airbag.

[0050] Of course, in other embodiments, such as Figure 2 As shown, the seat may further include: a detection device 130 for detecting the tilt direction and tilt amplitude of the seat body 110; and a control module 160 connected to the detection device 130 and the inflation device 150 for sending an airbag inflation signal or a retractable airbag inflation signal to the inflation device 150 based on the detection results of the detection device 130. This design allows the seat to promptly detect the tilt of the seat body 110 and then promptly control the inflation and deployment of the retractable airbag 142 or the safety airbag 141, ensuring product safety.

[0051] In one specific embodiment, the detection device 130 includes multiple weighing devices, each connected to one of the multiple support legs 120, for detecting the weight borne by the support legs 120. When the seat body 110 tilts, the weight borne by each support leg 120 also changes accordingly. Therefore, by using multiple weighing devices to detect the weight borne by the multiple support legs 120, the tilt of the seat body 110 can be accurately reflected.

[0052] The control module 160 includes: a memory storing a first preset weight value and a second preset weight value; a comparator electrically connected to multiple weighing devices for comparing the weight value detected by the weighing devices on the outrigger 120 with the first preset weight value and the second preset weight value; and a processor electrically connected to the comparator, which can send a telescopic airbag inflation signal to the inflation device 150 when the weight value on any outrigger 120 is greater than the first preset weight value and less than the second preset weight value, and can also send an airbag inflation signal to the inflation device 150 when the weight on any outrigger 120 is greater than or equal to the second preset weight value.

[0053] The first preset weight value can be the maximum weight that the outriggers 120 can bear when the seat body 110 is about to tilt, and the second preset weight value can be the maximum weight that the outriggers 120 can bear when the seat body 110 is about to recline. This ensures that the seat can accurately determine the tilt of the seat body 110 and promptly control the inflation and deployment of the corresponding airbags, resulting in good protective performance.

[0054] Of course, when the weight borne by the support leg 120 exceeds the first preset weight value, the control module 160 determines that the seat is tilted, requiring the support leg 120 in the tilting direction to extend to adjust the balance. However, at this time, the support leg 120 can be raised off the ground or remain in contact with the ground; this determination scale can be designed as needed. Similarly, when the weight borne by the support leg 120 exceeds the second preset weight value, the control module 160 determines that the seat is about to tip over. However, at this time, the seat can have a certain degree of tilt without necessarily tipping over, or the seat can tilt too much and inevitably tip over; this determination scale can also be designed as needed.

[0055] To avoid the constant shifts in the center of gravity caused by frequent movement of children, which would require the telescopic outrigger 120 to adjust continuously, the telescopic outrigger 120 can be extended only when the center of gravity shifts significantly, and the airbag 141 can be extended only when the center of gravity shifts particularly large, thus improving the user experience.

[0056] Additionally, it should be noted that the first and second preset weight values ​​can be obtained through extensive simulation experiments and pre-written into the memory of the control module 160 for easy retrieval. For example, different first and second preset weight values ​​corresponding to different body weights can be obtained through pre-experimentation. When a user is placed in the seat body 110, the corresponding first and second preset weight values ​​can be retrieved based on the user's weight. Then, as the user's center of gravity shifts, the weight detected by the weighing device is compared with the retrieved first and second preset weight values ​​to determine the tilt of the seat body 110.

[0057] The first and second preset weight values ​​can also be calculated based on the initial weight of the user placed on the seat body 110. For example, a corresponding algorithm is pre-stored in the memory. When the user is placed on the seat, the weighing device obtains the initial weight values ​​of each support leg 120, and then calculates the first preset weight value borne by the support leg 120 when the seat body 110 is about to tilt and the second preset weight value borne by the support leg 120 when the seat body 110 is about to fall over, based on the corresponding algorithm and this initial value. Then, as the user's center of gravity shifts, the processor compares the real-time weight detected by the weighing device with the retrieved first and second preset weight values ​​to determine the tilt status of the seat body 110.

[0058] In this way, as users differ or their weight changes, the weighing device can detect the weight borne by the support leg 120 to reflect the seat's tilt, thus improving the seat's versatility.

[0059] Furthermore, the control module 160 in this embodiment can be an integrated structure, with the comparator, processor, and memory integrated together, or even as a single component. Alternatively, the control module 160 can be a separate structure, with components distributed across the board. The control module 160 can integrate storage, comparison, and signal transmission functions. Similar to control structures with related functions in the prior art, it will not be described in detail here.

[0060] Let's take putting a baby in a car seat as an example. Figure 5 As shown, when using the seat, it is necessary to fully unfold it and turn on the airbag protection switch on the control module 160. The weighing devices on the four support legs 120 will automatically reset to zero. After the baby is placed in the seat, the four weighing devices will record the current weight value and retrieve the seat tilt limit weight value A (the first set weight value corresponding to the current baby's weight) and the seat tilt limit weight value B (the second set weight value corresponding to the current baby's weight) from the memory. After that, the weighing devices on the support legs 120 will monitor the weight data in real time and transmit the four weight data to the processor for comparison with the two values ​​A and B. When the weight value is greater than A and less than B, the processor determines that the seat is tilted but not tipped over. It will open the leg air pump solenoid valve and send the corresponding telescopic airbag inflation signal to the inflation device 150 so that the inflation device 150 sends an inflation signal to at least one telescopic airbag 142 adjacent to the tilt direction. The telescopic airbag 142 inside the support leg 120 will expand and push the external tube section to achieve height extension and contraction, maintaining the balance of the seat body 110. At the same time, the buzzer 170 will be controlled to sound an alarm and remind the guardian. When the weight value exceeds B, the control module 160 determines that the seat body 110 is tilting and sends an airbag inflation signal to the inflation device 150. The airbags 141 located at the top and sides of the seat body 110 are deployed, providing cushioning when the seat tilts and preventing injury to the baby. Simultaneously, the buzzer 170 can be activated to alert the caregiver. Of course, the seat can also connect to a mobile phone, camera, etc., via Wi-Fi or Bluetooth to provide vibration, sound, and light alerts, or remote alarm reminders from the manufacturer.

[0061] Specifically, when the baby is sitting in the high chair, the weighing device generates a signal change when the baby swings around or climbs out of the seat. The weight signal from the weighing device is transmitted to the control module 160, which controls the telescopic airbag 142 on the side with the greater weight to unfold and extend in order to adjust the seat posture and center of gravity.

[0062] Once the baby returns to the center of gravity, or after the baby is removed from the seat, the weighing device can detect the weight returning to its initial value. Based on this, the vent valve can be opened to release the gas in the retractable airbag 142, facilitating the return of the outrigger 120 to its initial height. Alternatively, the user can press a corresponding vent button to control the venting of the retractable airbag 142. Furthermore, venting can also be achieved through the inflation device 150, for example, by having the inflation device 150 draw gas out of the retractable airbag 142. There are various methods for controlling and venting the retractable airbag 142, which will not be detailed here. Similarly, the venting method for the airbag 141 can be similar to that of the retractable airbag 142.

[0063] In addition to using a weighing device to detect the tilt of the seat body 110, the detection device 130 can also have other structures. For example, the detection device 130 includes a tilt sensor, which uses the principle of gravity to calculate the tilt angle of the seat body 110 relative to the horizontal plane by detecting the components of gravitational acceleration in different axes, thereby determining the tilt of the seat body 110. As another example, the detection device 130 includes multiple trigger rods, each correspondingly mounted on one of the support legs 120. When the seat body 110 tilts, at least one of the trigger rods is triggered by pressure from the ground, and the tilt of the seat body 110 is determined based on the triggering status of the multiple trigger rods. The specific structure of the detection device 130 can vary, as long as it can detect the tilt of the seat body 110.

[0064] Furthermore, in some embodiments, such as Figure 1 As shown, the seat also includes a buzzer 170 and / or a warning light, electrically connected to the control module 160. The control module 160 can also send an alarm signal to the buzzer 170 and / or send an illumination signal to the warning light based on the detection results of the detection device 130. This facilitates alerting others that the seat has tilted or fallen over, improving product safety.

[0065] In addition, such as Figure 1 As shown, the control module 160 and the buzzer 170 can be installed on the back of the seat body 110 for easy installation. An operation panel can also be installed on the back of the seat body 110. The operation panel is electrically connected to the control module 160 and the buzzer 170, allowing users to control the inflation module, buzzer 170, etc., via the operation panel.

[0066] like Figure 1 As shown, the inflation device 150 is located at the bottom of the seat body 110 and is hidden under the seat body 110, which has a good appearance.

[0067] Furthermore, in some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the seat also includes a tray 180, which is connected to the seat body 110. The tray 180 contains a heating element 183 and a temperature sensing module 184. The heating element 183 heats the tray 180, and the temperature sensing module 184 detects the temperature of the tray 180. Thus, the seat can be used as a dining chair, and the heating of the tray 180 allows for the heating of food placed on it, helping to maintain food temperature and improve the user experience.

[0068] In practical applications, the 180 plate can be a temperature-controlled plate with multiple temperature settings for users to adjust.

[0069] Furthermore, such as Figure 4 As shown, the plate 180 also includes an indicator light 185, disposed within the plate 180, which illuminates when the heating element 183 is heating to alert the user, reducing the chance of burns. Furthermore, the indicator light 185 can be turned off when the heating element 183 is turned off.

[0070] Furthermore, such as Figure 4 As shown, the plate 180 also includes a plate base 181 and a plate cover 182. The plate base 181 and the plate cover 182 form an accommodating space, and the heating element 183, the temperature sensing module 184 and the indicator light 185 are all disposed within the accommodating space.

[0071] Furthermore, such as Figure 2 and Figure 4 As shown, armrests 112 are provided on both sides of the seat body 110, and the plate 180 is connected to the armrests 112.

[0072] As an example, such as Figure 2 and Figure 4 As shown, the front end of the armrest 112 is provided with a connection hole 1121, and a first connection electrode is provided inside the connection hole 1121. The end of the tray 180 facing the seat body 110 is provided with two connection posts, and the end of each connection post is provided with a second connection electrode 187. The connection posts are inserted into the corresponding connection hole 1121, and the first connection electrode and the second connection electrode 187 are electrically connected. The second connection electrode 187 is electrically connected to the heating element 183, the temperature sensing module 184, and the indicator light 185, so that the seat can supply power to the tray 180.

[0073] Furthermore, in some embodiments, the seat also includes a battery or power module (not shown) connected to the inflation device 150 for supplying power to the inflation device 150. This allows power to be provided for inflating the inflation device 150.

[0074] Furthermore, in some embodiments, such as Figure 1 and Figure 2As shown, the bottom of the support leg 120 is equipped with a brake wheel 190 for easy seat movement.

[0075] Furthermore, in some embodiments, the seat is a child high chair.

[0076] While the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope thereof. It should be understood that, to those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
