Description

Technical Field

[0001] This utility model relates to the field of bus seat technology, and in particular to a bus passenger seat with multifunctional armrests. Background Technology

[0002] As a common long-distance mode of transportation, the comfort of passenger seats in buses directly affects the riding experience. To improve comfort, existing bus seats are usually equipped with headrests to support passengers' heads.

[0003] However, in actual use, it has been found that traditional headrest designs mainly focus on supporting the back of the head, and most only have height adjustment functions. Although this design can accommodate passengers of different heights, it ignores the physiological curve of the human cervical spine.

[0004] Specifically, when passengers lean back, there is often an unsupported gap between their neck and the headrest. In order to maintain the head posture, the passenger's neck muscles need to be constantly tense. During long journeys, this state can easily lead to neck pain and fatigue, greatly reducing the comfort of the ride. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bus passenger seat with a multi-functional armrest, aiming to improve the problems of poor fit of the headrest to the passenger's neck, inconvenient adjustment of the support angle, and unreliable locking in the existing bus seat headrest.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A passenger seat for a bus with multifunctional armrests includes: a seat cushion, a bracket for supporting the seat cushion, and a backrest mounted on the bracket. A headrest is connected to the upper end of the backrest, and a neck pillow is rotatably connected to the headrest. A rotating assembly and a latching assembly are disposed between the headrest and the backrest. The rotating assembly includes a first connecting plate, a rotating shaft, a first rotating plate, a second connecting plate, a second rotating plate, and a third connecting plate. The latching assembly includes a hollow column, a ball joint, and a second spring. The first connecting plate is fixed inside the headrest. The rotating shaft is rotatably mounted on the first connecting plate. The first rotating plate is sleeved on the rotating shaft. One end of the second connecting plate is connected to the neck pillow, and the other end is connected to the first rotating plate. The second rotating plate is connected to the first rotating plate. One end of the third connecting plate is connected to the second rotating plate, and the other end is slidably connected to the inside of the backrest. The buckle assembly is fixed on the third connecting plate. Its hollow column houses the locking ball and the second spring. The second spring abuts against the locking ball so that the locking ball engages with the inner wall of the backrest.

[0007] Preferably, the inner wall of the backrest is provided with a plurality of positioning grooves distributed along the sliding path of the third connecting plate, and the ball is selectively engaged with the positioning grooves under the action of the second spring.

[0008] Preferably, the passenger seat of the bus further includes a side panel and an armrest, the side panel being fixedly connected to the bracket, and the armrest being hinged to the side panel.

[0009] Preferably, the passenger seat of the bus further includes an adjustment component for adjusting the height of the armrest. The adjustment component includes a telescopic column fixed to the side panel, and a handle, a locking pin, a first spring, and a hollow frame disposed on the armrest. The armrest is slidably sleeved on the telescopic column, and the locking pin is slidably disposed inside the hollow frame and selectively engages with the positioning hole opened on the outer wall of the telescopic column through the armrest.

[0010] Preferably, the handle is connected to the locking post for driving the locking post to disengage from the telescopic post; the first spring is sleeved on the outer periphery of the locking post for pushing the locking post to reset after the handle is released.

[0011] Preferably, the passenger seat of the bus also includes a footrest, which is rotatably connected between the side panel and the bracket.

[0012] Preferably, the first rotating plate and the second rotating plate are integrally formed.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by setting a rotating component and a buckle component linked to the neck pillow, the rotation of the neck pillow is converted into the sliding of the connecting plate inside the backrest through a linkage mechanism, and the buckle component composed of spring and ball is used to lock the sliding position in stages. This solves the problems of poor neck support, poor fit, inability to make fine angle adjustments, and neck fatigue caused by long-term sitting in the existing bus seat headrests. It achieves the technical effect of being able to conveniently and quickly adjust the neck pillow support angle so that it can accurately fit the neck curve of different passengers and reliably lock the position, thereby significantly improving the riding comfort and support stability.

[0014] 2. In this utility model, by setting an armrest adjustment assembly including a telescopic column, a handle, and a spring-loaded locking column, the armrest can slide along the telescopic column, and by operating the handle, the locking column can be selectively engaged with the positioning hole on the telescopic column. This solves the problem in the prior art that the height of the seat armrest is fixed and cannot adapt to the arm placement needs of passengers of different sizes. It achieves the technical effect of conveniently adjusting the armrest height, improving the universality of the seat and the personalized comfort experience of passengers.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-7 One embodiment of this utility model is a bus passenger seat with a multi-functional armrest, including a bracket 10, a seat cushion 9 and a backrest 1 installed on the bracket 10, a headrest 5 connected to the upper end of the backrest 1, and a neck pillow 11 rotatably connected to the headrest 5. The core innovation of this seat lies in the rotating component 7 and the buckle component 8 set between the headrest 5 and the backrest 1. Through this structural combination, the precise adjustment and stable locking of the angle of the neck pillow 11 are achieved.

[0019] Specifically, the rotating assembly 7 includes a first connecting plate 702 fixed inside the headrest 5, a rotating shaft 701 rotatably mounted on the first connecting plate 702, and a first rotating plate 703 sleeved around the outer periphery of the rotating shaft 701. The rotating assembly 7 also includes a second connecting plate 704, one end of which is connected to the neck pillow 11, and the other end is connected to the first rotating plate 703, thereby transmitting the action of moving the neck pillow 11 to the first rotating plate 703 to make it rotate around the rotating shaft 701. The rotating assembly 7 further includes a second rotating plate 705. The first rotating plate 703 and the second rotating plate 705 are integrally formed with the third connecting plate 706, the first rotating plate 703 and the second rotating plate 705. One end of the second rotating plate 705 is fixedly connected to the first rotating plate 703, and the other end is connected to one end of the third connecting plate 706. The other end of the third connecting plate 706 is slidably connected to the inside of the backrest 1. In this way, the rotation of the neck pillow 11 is converted into the reciprocating linear sliding of the third connecting plate 706 inside the backrest 1 through the linkage mechanism composed of the second connecting plate 704, the first rotating plate 703 and the second rotating plate 705. In order to lock the adjusted angle of the neck pillow 11, the buckle assembly 8 is fixed to the third connecting plate 706 and slides together with it. The buckle assembly 8 includes a hollow column 802, and the hollow column 802 contains a locking ball 801 and a second spring 803. The second spring 803 abuts against the locking ball 801 and continuously applies a pushing force to the locking ball 801 so that the locking ball 801 and the inner wall of the backrest 1 form a locking engagement, so that when the adjustment action stops, the position of the third connecting plate 706 can be locked instantly, thereby fixing the angle of the neck pillow 11. The core components of the adjustment assembly 6 include a telescopic column 605 fixed to the side plate 3 and a handrail 2 slidably sleeved on the telescopic column 605. The adjustment assembly 6 also includes a hollow frame 601, a handle 602, a locking post 603 and a first spring 604 disposed on the handrail 2. The outer wall of the telescopic column 605 is provided with a plurality of positioning holes distributed along its length direction. The locking post 603 is slidably disposed inside the hollow frame 601, and one end of it passes through the wall of the handrail 2 and can be selectively inserted into any positioning hole of the telescopic column 605, thereby locking the handrail 2. During the adjustment process, the handle 602 is connected to the locking post 603. Pulling the handle 602 upward will cause the locking post 603 to move against the elastic force of the first spring 604, so that it is disengaged from the positioning hole on the telescopic post 605. At this time, the handrail 2 can slide freely along the length of the telescopic post 605 to adjust the height. When the adjustment is to a suitable position, the handle 602 is released. Under the elastic force of the first spring 604, the locking post 603 automatically resets and inserts into the nearest positioning hole, completing the locking of the new position of the handrail 2. The first spring 604 is sleeved on the outer periphery of the locking post 603, continuously providing pre-tightening force for the reset and locking of the locking post 603. To improve the reliability and step-by-step locking of the buckle assembly 8, multiple positioning grooves are provided on the inner wall of the backrest 1 along the sliding path of the third connecting plate 706. The locking ball 801 can selectively engage into one of the positioning grooves under the push of the second spring 803, thereby achieving precise locking of the different positions. To simplify the internal structure of the rotating assembly 7 and enhance transmission rigidity, the first rotating plate 703 and the second rotating plate 705 are designed as an integral structure, reducing assembly steps and the risk of potential loosening of connections. In the adjustment assembly 6 of the armrest 2, the first spring 604 is sleeved on the outer periphery of the locking post 603, and its two ends abut against the flange of the locking post 603 and the inner wall of the hollow frame 601 respectively, providing a stable and direct elastic force for the locking post 603 to reset. As a further improvement in seat comfort, the seat also includes a footrest 4, which is rotatably connected between the side plate 3 and the bracket 10 via a pivot, so that it can be flipped to the storage position or unfolded to the use position.

[0020] Working principle: When the angle of the neck pillow 11 needs to be adjusted, the passenger moves the neck pillow 11, which drives the second connecting plate 704 to move. The second connecting plate 704 then pushes the first rotating plate 703 to rotate around the rotating shaft 701. Since the first rotating plate 703 and the second rotating plate 705 are an integral structure, the second rotating plate 705 rotates synchronously and pushes the third connecting plate 706 to slide inside the backrest 1. During the sliding of the third connecting plate 706, the buckle assembly 8 fixed on it also moves. The locking ball 801 inside slides along multiple positioning grooves on the inner wall of the backrest 1 under the elastic force of the second spring 803. When the passenger stops adjusting and releases the neck pillow 11, the locking ball 801 is pushed by the second spring 803 and then locks the position of the third connecting plate 706, thereby fixing the entire rotating assembly 7 and finally stabilizing the neck pillow 11 at the required support angle. When the height of the armrest 2 needs to be adjusted, the user pulls the handle 602 upwards. The handle 602 moves the locking post 603 within the hollow frame 601 and compresses the first spring 604, causing the front end of the locking post 603 to disengage from the positioning hole of the telescopic post 605, thus releasing the lock on the armrest 2. At this time, the armrest 2 can be moved up and down to the appropriate height. After releasing the handle 602, the compressed first spring 604 rebounds, pushing the locking post 603 to reset and re-insert into the new positioning hole on the telescopic post 605, completing the adjustment and locking of the armrest 2's height.
