[0025] Existing car seats cannot simultaneously meet the needs of children riding, adults resting, and expanding storage. Adding extra child seats is cumbersome and takes up space, temporary rest requires additional expenses, and storage space lacks flexibility.
[0026] Based on the above issues, such as Figures 1 to 11 As shown, this application proposes an integrated car seat for adults and children, which adopts a "one-bottom, two-top" sliding rail layout. Two parallel lower sliding rails 1 serve as the base rails for fixing to the car body. Each lower sliding rail 1 has a seat cushion upper sliding rail 2 slidably mounted at its front end and a backrest upper sliding rail 3 slidably mounted at its rear end. A backrest assembly 4 is mounted on the backrest upper sliding rail 3, and a seat cushion assembly 5 is mounted on the seat cushion upper sliding rail 2. The backrest assembly 4 includes a main backrest 41 and a main backrest angle adjuster 42. The upper end of seat 41 is detachably connected to a headrest assembly 9. The seat cushion assembly 5 includes a main seat cushion 51 and a lifting mechanism 8. A child seat assembly 6 and a leg rest assembly 7 are disposed on the main seat cushion 51. The child seat assembly 6 includes a child seat angle adjuster 61, a child seat backrest 62, and a child seat headrest assembly 63. The child seat headrest assembly 63 includes a child seat headrest 631 and a child seat telescopic mechanism 632. The leg rest assembly 7 includes a leg rest plate 71, a leg rest telescopic mechanism 72, and a leg rest lifting mechanism 73. The angle adjusters used are angle adjusters commonly used in the automotive seat technology field.
[0027] With this configuration, the backrest assembly 4 and the seat cushion assembly 5 are adjusted independently via sliding rails, without interfering with each other. This allows the backrest travel to reach 180°, enabling it to be laid flat forward to expand storage space or laid flat backward to achieve a reclining position. It can also be locked at any angle to adapt to different usage scenarios.
[0028] In some embodiments, the lifting mechanism 8 includes a motor screw drive assembly 81 and a four-bar linkage assembly 82. A first front connecting plate 83 is disposed between the two seat cushion slide rails 2. The motor screw drive assembly 81 is installed between the bottom of the main seat cushion 51 and the first front connecting plate 83. The four links of the four-bar linkage assembly 82 are respectively hinged between the front and rear ends of both sides of the main seat cushion 51 and the corresponding seat cushion slide rails 2. Compared with ordinary seat height adjustment motors, the screw drive structure is more compact and has stronger thrust. Combined with the four-bar linkage assembly 82, it can realize the smooth lifting and lowering of the main seat cushion 51, meeting the height adjustment needs of the child mode.
[0029] In some embodiments, a lower backrest connecting plate 43 is provided on the upper backrest slide rail 3, and an upper backrest connecting plate 44 is hinged to the lower backrest connecting plate 43. The main backrest 41 is disposed between the two upper backrest connecting plates 44, and a synchronizing rod 45 is provided between the two upper backrest connecting plates 44. Under the drive of the main backrest angle adjuster 42, the two upper backrest connecting plates 44 rotate relative to the two lower backrest connecting plates 43 to ensure that the main backrest 41 is subjected to uniform force and has a stable posture during adjustment, and can be locked at any position.
[0030] In some embodiments, a front lead screw 10 is fixedly installed at the front end of the lower slide rail 1, and the two upper slide rails 2 of the seat cushion are connected by a second front connecting plate 11. A seat cushion drive motor 12 and a seat cushion transmission rod 13 are installed on the second front connecting plate 11, and seat cushion transmission sleeves 14 at both ends of the seat cushion transmission rod 13 are screwed into the front lead screw 10. When the seat cushion drive motor 12 is started, the seat cushion transmission rod 13 drives the seat cushion transmission sleeves 14 to slide along the front lead screw 10, realizing the forward and backward translation of the seat cushion assembly 5, which is precise and stable. It should be understood that the seat cushion drive rod 13 is a rotary motion, which drives the seat cushion drive sleeve 14 to rotate through transmission components such as gear transmission and sprocket transmission. The seat cushion drive sleeve 14 is screwed with the front lead screw 10. The seat cushion drive sleeve 14 is fixedly connected to the upper slide rail 2 of the seat cushion by bolts or buckles. The upper slide rail 2 of the seat cushion is slidably assembled on the lower slide rail 1. Its sliding direction is restricted by the lower slide rail 1. It can only move in the front and back direction and cannot deflect left and right or rotate circumferentially. Therefore, the seat cushion drive sleeve 14, which is fixed to the upper slide rail 2 of the seat cushion, is forcibly restricted in its circumferential rotational freedom and only retains its axial movement freedom.
[0031] The rear end of the lower slide rail 1 is fixedly provided with a rear lead screw 15. The two upper slide rails 3 of the backrest are connected by a rear connecting plate 16. Similarly, the backrest drive motor 17 drives the backrest transmission rod 18 to rotate. Through the screw engagement between the backrest transmission sleeve 19 and the rear lead screw 15, the backrest assembly 4 can move independently forward and backward. The structure is consistent with the seat cushion drive, ensuring the synchronization and reliability of the adjustment.
[0032] In some embodiments, the leg support telescopic mechanism 72 includes a leg support frame 721 and a leg support telescopic motor 722. A leg support slide rail 723 is provided between the leg support plate 71 and the leg support frame 721. The leg support telescopic motor 722 is a lead screw motor, with its motor end located on the leg support frame 721 and its lead screw end connected to the leg support plate 71. It directly drives the leg support plate 71 to extend and retract along the leg support slide rail 723. The extension length can be flexibly adjusted to meet the needs of users of different heights.
[0033] The leg support lifting mechanism 73 includes two leg support four-bar linkages 731 and a leg support lifting motor 732. The two leg support four-bar linkages 731 are respectively disposed on both sides of the leg support frame 721 and the main seat cushion 51. Each linkage includes a first link 7311, a second link 7312, a third link 7313, and a fourth link 7314. One end of the first link 7311 is hinged to the main seat cushion 51, and the other end is hinged to the second link 7312. The middle part of the second link 7312 is hinged to the third link 7313, and the end of the second link 7312 away from the first link 7311 is hinged to the leg support frame 721. One end of the third link 7313 is hinged to the main seat cushion 51, and the other end is hinged to the fourth link 7314. The end of the fourth link 7314 away from the third link 7313 is hinged to the leg support 721. A drive shaft 7315 is provided between the two third links 7313, and a connecting rod 7316 is provided between the two fourth links 7314. The leg support lifting motor 732 is a lead screw motor, with its motor end located on the main seat cushion 51 and its lead screw end connected to the drive shaft 7315. The transmission is precise and the thrust is sufficient, which can stably lift the leg support plate 71 to a horizontal position.
[0034] In summary, through the coordinated action of various adjustment mechanisms, six functional modes can be quickly switched. Specifically, these are: adult seating mode, zero-gravity seating mode, reclining mode, suitcase mode, child seating mode, and toddler seating mode. More specifically: Adult riding mode: The adult riding mode is the basic mode. In this mode, the child seat backrest 62 is folded and fits against the main seat cushion 51, forming a flat adult riding surface together with the main seat cushion 51. The headrest assembly 9 is installed in place. In this mode, the corresponding backrest and seat cushion are adjusted to the normal riding angle to meet the daily driving and riding needs of adults. The folded child seat assembly 6 does not take up extra space, ensuring the comfort of adult riding.
[0035] Zero-gravity riding mode: In adult riding mode, the main backrest 41 is rotated to a zero-gravity angle of about 120° by electrically controlling the main backrest angle adjuster 42. At the same time, the leg support lifting mechanism 73 is activated to lift the leg support plate 71. The leg support extension mechanism 72 drives the leg support plate 71 to extend away from the main seat cushion 51, so that the human body is in a natural and relaxed zero-gravity posture, reducing fatigue during long-distance driving.
[0036] Flat Reclining Mode: Based on the adult seating mode, the main backrest 41 is rotated to a horizontal position via the main backrest angle adjuster 42. Simultaneously, the leg rest lifting mechanism 73 raises the leg rest 71 to a horizontal position. Once fully extended, the leg rest 71, along with the main backrest 41 and main seat cushion 51, forms a complete flat reclining surface, meeting the user's temporary sleep needs without requiring additional accommodation. Most existing car seats cannot achieve a perfectly flat reclining surface; this car seat, through its sliding rail adjustment, avoids interference between mechanisms. Furthermore, in flat reclining mode, the child seat assembly 6 can be adjusted independently, providing lumbar comfort compensation when lying flat.
[0037] Luggage Mode: In adult seating mode, the backrest drive motor 17 drives the backrest transmission rod 18 to rotate, causing the backrest transmission sleeve 19 to move the backrest upper slide rail 3 and backrest assembly 4 backward to their extreme positions along the rear lead screw 15. Simultaneously, the seat cushion drive motor 12 drives the seat cushion transmission rod 13 to rotate, causing the seat cushion transmission sleeve 14 to move the seat cushion upper slide rail 2 and seat cushion assembly 5 forward to their extreme positions along the front lead screw 10. Finally, the main backrest angle adjuster 42 rotates the main backrest 41 forward to a horizontal position. At this point, the overall space occupied by the seat is minimized, creating a significantly expanded storage area inside the vehicle, suitable for scenarios such as moving and transporting large items. In addition, the main backrest 41 can be laid flat to be level with the trunk, forming a large bed, which can also be used for temporary rest.
[0038] Child Seating Mode: The motor-driven screw assembly 81 and the four-bar linkage assembly 82 of the lifting mechanism 8 work together to lift the seat cushion assembly 5 as a whole. At the same time, the backrest assembly 4 moves forward horizontally. The folded child seat backrest 62 serves as the child seat cushion, forming a seating space suitable for children aged 3 to 12 years old in conjunction with the headrest assembly 9, without the need for an additional child seat. In this mode, the original adult seat belt can be used directly.
[0039] Infant Seating Mode: The lifting mechanism 8 raises the main seat cushion 51 to serve as a special seat cushion for infants. Activating the child seat angle adjuster 61 rotates the child seat backrest 62 away from the main backrest 41 to a protective position. The child seat extension mechanism 632 drives the child seat headrest 631 upwards, forming a complete protective seating structure for infants, suitable for the safety needs of young children. In this mode, a five-point harness is sufficient to meet the seating needs of children aged 3 and under.
