In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The invention provides a backrest component of a vehicle seat, wherein the backrest component comprises an upper assembly 1 and a lower assembly 2, the lower assembly 2 can rotate around a horizontal first rotation axis relative to a cushion part of the vehicle seat between an upward extending seat position and a forward extending bed seat position, the upper assembly 1 can rotate relative to the lower assembly 2 between a first position corresponding to the seat position and a second position corresponding to the bed seat position, in the first position, a front surface of the upper assembly 1 is smoothly connected with a front surface of the lower assembly 2, and in the second position, the upper assembly 1 is protruded relative to a rear surface of the lower assembly 2.
The backrest module and the substantially horizontally disposed seat cushion are coupled to each other to form a vehicle seat, and the backrest module may be coupled to a rear side of the seat cushion to provide support for a back of a seated person.
In this solution, referring to fig. 1, the backrest module comprises an upper assembly 1 at the upper part and a lower assembly 2 at the lower part, wherein the lower assembly 2 can rotate around a first rotation axis relative to the seat cushion part, i.e. the backrest module rotates around the first rotation axis. Wherein the lower assembly 2 is in a seat position when extended upwardly, allowing an occupant to sit on the seat cushion and be supported on the back assembly; when the lower assembly 2 is rotated to the forwardly extending bed-chair position, its rear surface can serve as a bed surface for supporting a passenger upwardly, i.e. the backrest assembly occupies the space originally occupied by the passenger in the sitting position to form a bed structure, and in particular the rear side of the seat is provided with other support structures which can form a bed body of larger size together with the backrest assembly. Wherein, the lower end of the lower assembly 2 can form a through hole for accommodating the rotating shaft, or the lower end of the lower assembly 2 is provided with the rotating shaft, thereby realizing the rotatable connection between the lower assembly 2 and the cushion part, of course, the lower assembly 2 can also be connected to other structures of the vehicle as long as the lower assembly can rotate relative to the cushion part.
In particular, the upper assembly 1 is movable relative to the lower assembly 2, the upper assembly 1 being movable to a first position when the lower assembly 2 is in the seating position, in which the front surface of the upper assembly 1 and the front surface of the lower assembly 2 are on the same side and substantially flush, forming a smooth curved support surface or plane which supports the upper part or head of the occupant, and the upper assembly 1 being movable to a second position when the lower assembly 2 is in the bed position, the upper assembly 1 projecting relatively to form a pillow structure for supporting the head.
In this scheme, the back subassembly sets up to rotate forward for the form that stretches out forward, can utilize the anterior space of seat and form and support the bed structure, and is unusual, the inside finite space of make full use of vehicle forms the bigger bed body of size, provides more comfortable rest environment for the user, has promoted user's experience with the car.
Wherein in the first position the upper assembly 1 and the lower assembly 2 are engaged with each other and in the second position the upper assembly 1 and the lower assembly 2 are spaced apart from each other. As shown in fig. 2, the upper assembly 1 is extended away from the lower assembly 2 in the second position relative to the first position, which makes the overall length of the backrest module larger when the lower assembly 2 is in the bed-chair position, and makes full use of the space inside the vehicle, especially the limited space in the front of the seat, so that the space of the formed bed is larger, and a larger rest space is provided for passengers. In other embodiments, in the second position, the upper assembly 1 and the lower assembly 2 may remain engaged without separation.
Further, the rear surface of the lower assembly 2 is provided with a support plate 3 movable between a third position attached to the rear surface of the lower assembly 2 and a fourth position extending from the lower assembly 2 to the upper assembly 1. As shown in figure 4, the support plate 3 is attached to the lower assembly 2 and is in a third position, as shown in figure 2, when the upper assembly 1 is extended relative to the lower assembly 2 and is spaced from the lower assembly 2, the support plate 3 can be moved to the spacing between the upper assembly 1 and the lower assembly 2 to form part of a bed to provide upward support for a user. The supporting plate 3 can be connected to the lower assembly 2 in a sliding or rotating manner, and correspondingly, a sliding rail or rotating shaft structure is arranged on the lower assembly 2; and a structure, such as a snap structure or a magnetic attraction structure, which can be attached to the support plate 3 is provided on the lower assembly 2, so that the support plate 3 can be stably held at the third position.
In addition, one of the upper assembly 1 and the lower assembly 2 is provided with a rotation shaft 4 extending from the upper assembly 1 toward the lower assembly 2, and the other is provided with a bushing 5 capable of accommodating the rotation shaft 4 to rotate. As shown in fig. 3 and 4, the rotation shaft 4 is provided on the upper assembly 1 and the sleeve 5 is provided on the lower assembly 2, but of course, the rotation shaft 4 may be provided on the lower assembly 2 and the sleeve 5 is provided on the upper assembly 1. As shown in fig. 3, the pivot shaft 4 is located close to the rear surface of the lower assembly 2, so that the front surface and the rear surface of the upper assembly 1 are flush with the front surface and the rear surface of the lower assembly 2, respectively, when in the first position, and protrude with respect to the rear surface of the lower assembly 2 when pivoted to the second position, in which configuration the front surface of the upper assembly 1 can be used to support the head of an occupant in both the first position and the second position. In other embodiments, the rotating shaft 4 may not be provided with a rotating guide rib, and the distance between the upper assembly 1 and the lower assembly 2 is kept constant when the upper assembly rotates around the rotating shaft 4 relative to the lower assembly.
In other embodiments, the upper assembly 1 may be arranged to move in a forward-rearward direction relative to the lower assembly 2, and likewise may be such that the front surface of the upper assembly 1 is flush with the front surface of the lower assembly 2 when in the first position, and the rear surface thereof projects relative to the rear surface of the lower assembly 2 when moved rearwardly to the second position, to act as a head-supporting pillow.
Further, a spiral guide rib 6 is provided on an outer circumferential surface of the rotating shaft 4, and a slide groove for accommodating the guide rib 6 is provided on an inner circumferential surface of the sleeve 5. In this configuration, as the upper assembly 1 rotates relative to the lower assembly 2 about the axis of rotation 4, the guide ribs 6 slide in the slide slots, which allows the upper assembly 1 to be extended or retracted relative to the lower assembly 2, allowing the upper assembly 1 to engage the lower assembly 2 in a first position and be spaced from the lower assembly 2 in a second position. In other embodiments, the rotating shaft 4 may be caused to move axially relative to the upper assembly 1 or the lower assembly 2, such that the upper assembly 1 may be moved directly relative to the lower assembly 2 toward the lower assembly 2 or away from the lower assembly 2.
