Description

[Technical Field]

[0001] The present invention relates to a vehicle seating system, and more particularly to a vehicle seating system that is lateral movable and rotatable. [Background technology]

[0002] 2. Description of the Related Art With the widespread use of automobiles, using automobiles as a means of transportation and transport in daily life has already become extremely common. However, for those with lower back injuries or mobility issues, such as those suffering from lower back pain, herniated discs, patients recovering from spinal surgery, or other lower back-related conditions, getting in and out of the driver's or passenger's seat often involves significant inconvenience and discomfort. This discomfort primarily stems from the bending, twisting, or leg lifting required to get in and out of the vehicle, which can put extra strain on the lower back and potentially worsen pain symptoms, as well as increase the risk of re-injury.

[0003] Although some assistive devices, such as portable step or handrail devices, are already found in the existing market, many of these devices require additional installation or are only applicable to the rear seats of a vehicle, and are not improved for driver or passenger seat use situations. Therefore, there are still many limitations in practicality, making it difficult to meet actual demands. Summary of the Invention [Problem to be solved by the invention]

[0004] The above prior art still has many limitations in practicality, and has the drawback of being difficult to meet actual needs. [Means for solving the problem]

[0005] The technical problem to be solved by the present invention is to address the above-mentioned drawbacks of the prior art and to provide an automobile seating device that allows the front seats of an automobile to be slid sideways and rotated.

[0006] The laterally movable and rotatable automobile seat device according to the present invention is applied to a front seat of an automobile, and the automobile seat device has a first sliding base, a second sliding base, a rotating base, and a locking member; The first sliding base is arranged along the automobile seat sliding rail, and the first sliding base can move back and forth along the traveling direction of the automobile, and a first side sliding part is provided on the first sliding base; The second slide base is provided with a second side slide portion, and the second side slide portion is fitted to the first side slide portion, so that the second slide base can slide freely relative to the first slide base in a direction perpendicular to the traveling direction of the vehicle; The rotating base is disposed between the second sliding base and the front seat of the automobile, The locking member is installed on the periphery of the rotating base, and operates between a locked position and an unlocked position. In the locked position, the front seat of the vehicle cannot rotate relative to the second sliding base, and the front seat of the vehicle remains in the same direction as the direction of travel of the vehicle. In the unlocked position, the front seat of the vehicle can rotate relative to the second sliding base toward the vehicle door.

[0007] This allows the front seat of the car to be slid sideways and even rotated, allowing the user to get in and out of the car with less strain, eliminating the need for excessive bending forward or lifting of the legs when getting in and out, and ultimately reducing the strain on the lower back.

[0009] To clarify the core idea of ​​the present invention, specific embodiments are described below. Moreover, specific language is used to describe these embodiments in order to facilitate an understanding of the principles of the present invention. However, this does not limit the scope of the present invention.

[0010] Those skilled in the art may make various modifications or further improve and apply the technical features and principles of the present invention described in this specification, and these modifications and applications are also within the scope of the present invention. In addition, in order to improve the readability of the drawings, some elements that do not belong to the technical features are omitted and not drawn.

[0011] As shown in FIGS. 1 to 10, a laterally movable and rotatable automobile seating device 100 according to one embodiment of the present invention is used in a front seat 1 of an automobile. The front seat 1 of the automobile is a driver's seat or a passenger seat, and allows a user to easily get in and out of the driver's seat or passenger seat. The automobile seating device 100 includes a first sliding base 10, a second sliding base 20, a rotating base 30, and a locking member 40.

[0012] The first slide base 10 is arranged along the automobile seat slide rail 2, and the first slide base 10 can move back and forth along the traveling direction of the automobile. Above the first slide base 10, a first lateral slide portion 11 is installed. In this embodiment of the present invention, the front seat 1 of the automobile is the driver's seat, and the automobile seat slide rail 2 is a slide rail structure below the driver's seat. Two inner rails 12 are installed on the bottom surface of the first slide base 10, and the two inner rails 12 are arranged perpendicular to the first side slide portion 11. The automobile seat slide rail 2 is configured by two outer rails and two inner rails 12 slidably fitted together. Furthermore, the forward and backward sliding adjustment of the first slide base 10 can be manual or electrically adjusted.

[0013] A second lateral slide portion 21 is installed below the second slide base 20, and the second lateral slide portion 21 is adapted to the first lateral slide portion 11, thereby allowing the second slide base 20 to move relative to the first slide base 10 in a direction perpendicular to the direction of travel of the vehicle. In this embodiment of the present invention, the first side slide part 11 and the second side slide part 21 are fitted together by a slide rail structure. Moreover, the second slide adjustment of the second slide base 20 can be manual adjustment or electric adjustment.

[0014] The rotation base 30 is provided between the second slide base 20 and the front seat 1 of the automobile. As shown in Figures 2 and 4, the rotating base 30 has a base body 31 and a rotating disk 32, and the base body 31 is fixed to the upper surface of the second slide base 20, and the rotating disk 32 is fixed to the bottom surface of the front seat 1 of the automobile. The base body 31 has a rotation groove 311, and the rotating disk 32 is rotatably disposed therein. An arc-shaped guide rail 312 is installed on the inner wall of the rotation groove 311 , and a positioning block 321 is formed to protrude from the periphery of the turntable 32 and is provided so as to be movable along the guide rail 312 . The guide rail 312 has a first end 3121 and a second end 3122 . The set angle of the guide rail 312 is less than 180 degrees, for example, 120 degrees. This allows the turntable 32 of the present invention to rotate within a range of 120 degrees relative to the base body 31.

[0015] The locking member 40 is mounted on the periphery of the rotating base 30, and the locking member 40 is operable between a locked position and an unlocked position. In this embodiment of the present invention, the locking member 40 is mounted on the base body 31 and is located near the first end 3121 . The locking member 40 is an electrically controlled member and has a rod portion 41 that is extendable and contractible relative to the guide rail 312 .

[0016] As shown in Figures 1 and 4, when the positioning block 321 is positioned at the first end 3121 of the guide rail 312, the rod portion 41 restricts the positioning block 321 to the first end 3121, so that the locking member 40 is in the locked position. Moreover, in this locked position, the base body 31 and the rotating disk 32 cannot rotate relative to each other, and the front seat 1 of the automobile cannot rotate relative to the second slide base 20. Therefore, the front seat 1 of the automobile is held facing in the same direction as the direction of travel of the automobile, and is in a normal use state.

[0017] As shown in FIGS. 6 and 7, when adjusting the present invention, first, the second slide base 20 is moved laterally toward the vehicle door, and the front seat 1 of the automobile is moved closer to the outside of the vehicle body. Subsequently, when the rod portion 41 of the locking member 40 retracts from the guide rail 312, the locking member 40 is in the release position, and the base body 31 and the rotating disk 32 become relatively rotatable. As a result, the positioning block 321 moves toward the second end 3122 of the guide rail 312, and the automobile front seat 1 can rotate relative to the second slide base 20 toward the vehicle door. In this way, the front seat 1 of the automobile rotates to the angular position shown in FIG. Therefore, in this invention, the front seat 1 of the automobile can be moved laterally and rotated to allow the user to get in and out with less strain. For example, when a user gets into the car, he or she simply sits in the front seat 1 of the car in an ergonomic position, then rotates the front seat 1 toward the interior of the car, and then returns it to its original position. This makes it possible to avoid excessive bending forward or lifting of the legs when riding, thereby reducing the strain on the lower back.

[0018] As shown in FIG. 5, in one embodiment of the present invention, the locking member 40 is signal-connected to a vehicle transmission 50 and a vehicle central locking system 60 . When the vehicle transmission 50 is in the P range and the vehicle central locking device 60 is in the unlocked state, the locking member 40 enters the unlocked position. This allows the operation of the present invention to be performed only when the vehicle is stopped and the central locking is unlocked, preventing potential risks due to incorrect operation.

[0019] As shown in FIGS. 1, 4 and 5, an embodiment of the present invention further includes a sensing unit 70. The sensing unit 70 is signal-connected to the locking member 40 . The sensing unit 70 is configured as a proximity sensor, and has a sensing member 71 provided on the base body 31 and a sensed member 72 provided on the positioning block 321 . When the sensing member 72 reacts with the sensing member 71, the sensed member 72 reacts with the sensing member 71, and the locking member 40 enters the locking position. Therefore, when a user sits in the front seat 1 of the vehicle and rotates toward the interior of the vehicle, the positioning block 321 of the turntable 32 returns to the first end 3121 again, and the locking member 40 is activated due to the reaction between the sensed member 72 and the sensing member 71, and the rod portion 41 is inserted into the guide rail 312 again to regulate the positioning block 321. This returns the seat to the locked position, and the front seat 1 of the vehicle returns to its original position relative to the direction of travel of the vehicle and is locked, so that the front seat 1 of the vehicle cannot rotate and can be used for normal driving or riding conditions.

[0020] As shown in FIGS. 8 to 10, the front seat 1 of the present invention can be positioned obliquely relative to the vehicle body by first moving it a second way and then adjusting its rotation when in use. This allows the user to get on and off in an ergonomic posture, putting less strain on the user, and avoiding excessive bending forward or lifting the legs when getting on and off, thereby reducing strain on the lower back.

[0021] Although the present invention has been described above based on the best mode for carrying out the invention, those skilled in the art can modify it in various different forms without departing from the spirit and scope of the invention. The above embodiments are intended to illustrate the present invention, but not to limit the scope of the present invention. [Explanation of symbols]
