Description

Technical Field

[0001] The utility model relates to the field of automobile accessories, in particular to a seat armrest. Background Art

[0002] The armrests in the rear seats of automobiles are usually rotatable. In order to ensure that the armrests can be opened and closed normally, the rear end of the armrests needs to be movable inside the seat back. When the armrests are opened, there is a certain gap between them and the back plate. The wiring harness, frame and other related parts will be exposed outside through this gap. Figure 1 As shown, a fig leaf 1 is usually used to cover the gap, but the length of the fig leaf 1 cannot exactly match the corresponding gap, and a certain margin needs to be left to ensure that the fig leaf 1 is not torn. If the fig leaf 1 is too long, after the armrest is fully opened, the fig leaf 1 may be wrinkled, bulged or sunken, resulting in defects in appearance. In addition, usually this flexible fig leaf 1 needs to be installed inside the back panel through an elastic band 2, so that when the armrest is opened, the fig leaf 1 can be laid flatly in the gap position, such as patent CN204845631U (such as Figure 1 However, as time goes by, the elastic band 2 will gradually age and lose its elasticity, affecting the shielding effect of the fig leaf 1.

[0003] The structure of the hard tail curtain used for shielding in the prior art is fixed at the rear end of the armrest, but because it needs to rotate within the seat back panel following the flipping and opening movement of the armrest, a rotation space for the hard tail curtain needs to be reserved within the seat back panel, which places a relatively high requirement on the distance from the armrest to the back panel, making it difficult to use the hard tail curtain of this structure in vehicles with smaller interior space, and its applicability is greatly reduced. Utility Model Content

[0004] In view of the deficiencies existing in the above-mentioned prior art, the utility model provides a seat armrest, which solves the technical problem of low applicability of the hard tail curtain between the rear armrest and the seat backboard of the automobile seat in the prior art.

[0005] The utility model provides a seat armrest, comprising the armrest being arranged to rotate between a stowed position and an opened position relative to a seat back plate, during which the armrest passes through an intermediate position, a rear curtain body being arranged on the seat back plate for covering a gap between the armrest and the seat back plate, the rear curtain body being rotatably mounted on the seat back plate, when the armrest rotates from the stowed position to the intermediate position, the rear curtain body remaining stationary; when the armrest rotates from the intermediate position to the opened position, the rear curtain body rotates together with the armrest to cover the gap.

[0006] The utility model further improves the seat armrest in that a connecting plate is fixed to the rear end of the armrest, and when the armrest rotates from the stowed position to the middle position, the connecting plate approaches the rear curtain body; when the armrest rotates from the middle position to the open position, the connecting plate engages with the rear curtain body to drive the rear curtain body to rotate along with the armrest.

[0007] A further improvement of the chair armrest of the utility model is that a track is provided on the rear curtain body, and a pin rod matching the track is provided on the connecting plate. When the armrest rotates from the middle position to the open position, the pin rod moves along the track to drive the rear curtain body to rotate along with the armrest.

[0008] The utility model further improves the seat armrest in that the rear curtain body comprises an upper cover plate and two mounting plates which are located at the inner side of the upper cover plate and extend radially, and the track is arranged on the mounting plates.

[0009] A further improvement of the seat armrest of the utility model is that the mounting plate is radially extended from the inner side of the upper cover plate to form an integral piece.

[0010] The utility model further improves the seat armrest in that a receiving groove is provided on the seat back plate, and when the armrest rotates from the middle position to the open position, the two ends of the upper cover plate move in the receiving groove.

[0011] The chair armrest of the utility model is further improved in that the connecting plate comprises an L-shaped horizontal plate and a vertical plate, the horizontal plate is fixed to the armrest, and the pin rod is arranged on the vertical plate.

[0012] A further improvement of the chair armrest of the utility model is that the transverse plate is fixed to the inside of the armrest by bolts.

[0013] The seat armrest of the utility model is further improved in that an elastic member is connected between the rear curtain body and the seat back plate and is used to reset the rear curtain body from the open position to the retracted position.

[0014] A further improvement of the seat armrest of the utility model lies in that the elastic member is a torsion spring or a spring.

[0015] Compared with the prior art, the utility model has a positive and obvious effect. The utility model shortens the length of the structure installed at the rear end of the armrest by rotatably mounting the tail curtain body on the seat back, thereby reducing the space on the seat back for the seat armrest to rotate, and solves the technical problem of low applicability of the hard tail curtain between the rear armrest and the seat back in the prior art. The movement space of the seat armrest of the utility model is completely based on the length from the rotation center of the armrest to the connecting plate, and the movement trajectory is small. The space requirement for the armrest to the seat back is greatly reduced, and it can be applied to most independent armrests. At the same time, the shape of the plastic tail curtain can be defined according to customer requirements to meet the corresponding appearance design requirements. It has a simple structure and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] like Figure 1 to Figure 26 As shown, the utility model provides a seat armrest, the armrest 8 is arranged to rotate between a stowed position and an open position relative to a seat back plate 1, and during the middle position, a rear curtain body 2 covering the gap between the armrest 8 and the seat back plate 1 is arranged on the seat back plate 1, and the rear curtain body 2 is rotatably mounted on the seat back plate 1, when the armrest 8 rotates from the stowed position to the middle position, the rear curtain body 2 remains stationary; when the armrest 8 rotates from the middle position to the open position, the rear curtain body 2 rotates with the armrest 8 to cover the gap. In this embodiment, the rear curtain body 2 is made of a hard material, such as hard plastic or steel.

[0049] Specifically, Figure 4 , 5 As shown in 17, 18, 21, and 22, the stowed position is the initial position of the rear curtain body 2 when the armrest 8 is closed, and the rear curtain body 2 is hidden inside the seat back panel 1. Fig.19 , 20, 25, 26, 27 and 28, the open position is when the armrest 8 is opened to the horizontal, the rear curtain body 2 rotates to the end position, at which time the rear curtain body 2 extends from the gap between the armrest 8 and the seat back 1, and protrudes from the seat back 1, thereby covering the gap between the armrest 8 and the seat back 1.

[0050] like Figure 4 , 5 As shown in , 17, 18, 21, and 22, when the armrest 8 changes from the closed state to the open state, that is, when it is in the middle position and the armrest 8 is in the front half, the rear curtain body 2 remains stationary. When the armrest 8 enters the rear half, the connecting plate 7 rotates with the flipping of the armrest 8, as shown in FIG. Fig.23 and 24 As shown in FIG. 1 , when the pin rod 71 on the connecting plate 7 contacts the track 21 on the rear curtain body 2 and slides into the track 21, the rear curtain body 2 will rotate along with the turning of the connecting plate 7 until the armrest 8 reaches the open position, as shown in FIG. Fig.19 , 20 , 25, 26, 27 and 28, the rear curtain body 2 can just cover the gap between the armrest 8 and the seat back panel 1.

[0051] Preferably, a connecting plate 7 is fixed to the rear end of the armrest 8, and when the armrest 8 rotates from the stowed position to the middle position, the connecting plate 7 approaches the tail curtain body 2; when the armrest 8 rotates from the middle position to the open position, the connecting plate 7 engages with the tail curtain body 2 to drive the tail curtain body 2 to rotate along with the armrest 8.

[0052] Preferably, Figures 13-16 As shown, the rear curtain body 2 is provided with a track 21, and the connecting plate 7 is provided with a pin 71 matched with the track 21. When the handrail 8 rotates from the middle position to the open position, the pin 71 moves along the track 21 to drive the rear curtain body 2 to rotate along with the handrail 8. The track 21 is adapted to the shape of the connecting plate 7 and the position corresponds. When the handrail 8 is flipped to be horizontal, the connecting plate 7 can slide in from the opening position of the track 21, so that in the process of flipping to the horizontal, the connecting plate 7 drives the rear curtain body 2 to rotate to the open position. The pins 71 extend from both sides of the connecting plate 7. When the connecting plate 7 slides into the track 21, the pins 71 are slidably arranged in the track 21. The pins 71 are round rod-shaped, thereby reducing the friction of sliding in the track 21.

[0053] Preferably, Figures 8 to 11As shown, the rear curtain body 2 includes an upper cover plate and two mounting plates located on the inner side of the upper cover plate and extending radially, and the track 21 is arranged on the mounting plate. Specifically, the upper cover plate can be a single plate or multiple plates; the upper cover plate can be an arc-shaped surface bent toward the side of the seat back plate 1, or a flat surface. The shape of the upper cover plate can be adapted to the overall shape of the armrest, and the two mounting plates are respectively located near the two ends of the upper cover plate.

[0054] Preferably, the mounting plate extends radially from the inner side of the upper cover plate as an integral piece or the mounting plate is fixedly mounted on the upper cover plate. The mounting plate and the upper cover plate can be fixed by conventional fasteners or adhesively fixed, so that the upper cover plate and the mounting plate can rotate synchronously, thereby achieving the function of the upper cover plate covering the gap.

[0055] Preferably, Figure 7 , 20 , 24, 26, and 28, the seat back plate 1 is provided with a receiving groove 13, and when the armrest 8 rotates from the middle position to the open position, the two ends of the upper cover plate move in the receiving groove 13. The receiving groove 13 makes the length of the upper cover plate larger than the width of the cavity on the seat back plate 1 for accommodating the armrest, so that the two ends of the upper cover plate can be inserted into the receiving groove 13, and during the rotation process of the armrest 8, the gap between the two sides of the rear end of the armrest 8 and the seat back plate 1 can be covered.

[0056] Preferably, Fig.14 As shown, the connecting plate 7 includes an L-shaped horizontal plate and a vertical plate, the horizontal plate is fixed on the handrail 8, and the pin rod 71 is arranged on the vertical plate. Specifically, the vertical plate is formed integrally with the horizontal rod at a position slightly inclined toward one side of the horizontal plate, and the turning point between the vertical plate and the horizontal plate is rounded. The pin rod 71 is located on both sides of the vertical plate and on the end surface away from the horizontal plate, so that when the connecting plate 7 contacts the rear curtain body 2, it can slide into the track 21 at the first time. Furthermore, the pin rod 71 can also be a complete rod body structure that penetrates the vertical plate, as long as the pin rod 71 can extend out of the vertical plate.

[0057] Preferably, Fig.15 and 16 As shown, the horizontal plate is fixed to the inside of the handrail 8 by bolts or the horizontal plate is integrally formed on the handrail 8. The horizontal plate is a step-shaped plate adapted to the rear end of the handrail 8, and at least two bolt holes are provided on the horizontal plate. The horizontal plate is fixed to the internal position of the middle of the rear end of the handrail 8 through at least two bolt holes, so that after the handrail 8 is flipped open, the horizontal plate is located inside the handrail 8, and the vertical plate is inserted in the tail curtain, so as to prevent the connecting plate 7 from being exposed to the outside. At the same time, since the horizontal plate is fixed to the internal position of the middle of the rear end of the handrail 8, it has no effect on the appearance of the handrail 8 and can be applied to various types of handrails 8. If the installation method of the horizontal plate being integrally formed on the handrail 8 is adopted, the integrity of the handrail of the connecting plate 7 can be further guaranteed.

[0058] Preferably, Figure 8 , 9 As shown in FIGS. 11 and 29, an elastic member for resetting the rear curtain body 2 from the open position to the retracted position is connected between the rear curtain body 2 and the seat back 1. The elastic member allows the rear curtain body 2 to return to the initial position after the armrest 8 is closed, so that the rear curtain body 2 can cover the gap between the armrest 8 and the seat back 1 when the armrest 8 is opened next time. The elastic member can also be selected as a reset sleeve or a reset rod according to actual needs.

[0059] Embodiment 1, as Figures 8 to 12 As shown, the elastic member is a torsion spring 3, and a rotating shaft 4 is provided between the rear curtain body 2 and the seat back plate 1 for the torsion spring 3 to pass through. The first end of the torsion spring 3 is fixed to the rear curtain body 2, and the second end of the torsion spring 3 is fixed to the seat back plate 1. The two ends of the torsion spring 3 are respectively fixed to the rear curtain body 2 and the seat back plate 1, and are rotated by the rotating shaft 4. The rear curtain body 2 can be restored to its initial position after rotation by the elastic force of the torsion spring 3. The rotating shaft 4 and the torsion spring 3 are in two groups, and the two groups of rotating shafts 4 and torsion springs 3 are located on the relative outer sides of the two mounting plates. A clamping groove 22 for clamping the first end of the torsion spring 3 is provided on the relative outer sides of the two mounting plates, a bayonet 12 for clamping the second end of the torsion spring 3 is provided on the back plate, and a connecting hole 11 for the rotating shaft 4 to be plugged in is provided on the back plate. When the elastic member is a spring 9, there are two springs 9, and the first ends of the two springs 9 are fixed to the relative outer sides of the two mounting plates.

[0060] Embodiment 2, as Figures 27-29 As shown, the elastic member is a spring 9, a first end of the spring 9 is fixed to the rear curtain body 2, and a second end of the spring 9 is fixed to the seat back plate 1. The second end of the spring 9 is specifically fixed to the inner wall of the seat back plate 1 away from the rear curtain body 2, thereby providing a pulling force for the rear curtain to return to its initial position.

[0061] The utility model shortens the length of the structure installed at the rear end of the armrest by rotatably mounting the tail curtain body on the seat back, thereby reducing the space on the seat back for the seat armrest to rotate, and solves the technical problem of low applicability of the hard tail curtain between the rear armrest and the seat back in the prior art. The movement space of the seat armrest of the utility model is completely based on the length from the rotation center of the armrest to the connecting plate, and the movement trajectory is small, which greatly reduces the space requirement for the armrest from the seat back, and can be applied to most independent armrests. At the same time, the shape of the plastic tail curtain can be defined according to customer requirements to meet the corresponding appearance design requirements. It has a simple structure and strong practicality.

[0062] The parts not involved in the present utility model are the same as the prior art or can be implemented by the prior art. The above is only the preferred embodiment of the present utility model, and does not limit the present utility model in any form. Although the present utility model has been disclosed as the preferred embodiment, it is not used to limit the present utility model. Any technician familiar with this profession can make some changes or modify the technical content disclosed above to an equivalent embodiment of equivalent changes without departing from the scope of the technical solution of the present utility model. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still belongs to the scope of the technical solution of the present utility model.
