As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The first embodiment is as follows:

as shown in fig. 1 and 2, the utility model provides a sit dual-purpose car seat of sleeping in, including the bench 100 that crouches, the bench 100 includes base 1, cushion 2 and back 3, back 3 with 1 one end of base is articulated, be equipped with slide rail 4 on the base 1, but sliding connection has slide 5 on the slide rail 4, cushion 2 with the one end of keeping away from back 3 of slide 5 is articulated, back 3 can be around base 1 is rotatory to horizontal extreme position, cushion 2 can wind slide 5 is rotatory to horizontal extreme position, just back 3 with height is the same when cushion 2 all is located horizontal extreme position. At this time, the utility model can be used as a bed.

Wherein, the backrest 3 is arranged on the base through the left and right core external connecting plates of the angle adjuster, and the left and right core internal connecting plates are connected with the backrest framework. The angle adjustment and the forward turning to the horizontal position locking of the backrest are realized through the adjusting and locking functions of the core piece. The recliner belongs to the prior art, and the recliner is provided on the traditional seat, and the description is omitted.

In order to improve the riding comfort of the seat 200 and meet the safety requirement of the seat 200, a targeted improvement is made for the problems of the seat 200, a set of horizontal sliding devices (namely a sliding rail 4 and a sliding seat 5) are installed at the lower part of a cushion 2 of the seat 200, the sliding seat 5 of the cushion 2 is fixed on the sliding rail 4, the cushion 2 is driven to move forwards by the forward sliding of the sliding seat 5, the space for flatting a backrest 3 is increased, the design height of the backrest 3 can meet the ergonomic requirement, and a headrest 14 and a three-point safety belt can be installed on the backrest 3 to meet the legislative requirement of the automobile seat 200.

Optionally, as shown in fig. 3 and 5, a first rotating support column 6 is fixedly arranged on the base 1, a first front limit baffle 7 and a first rear limit baffle 8 are respectively arranged on two sides of the first rotating support column 6, the backrest 3 is hinged to the first rotating support column 6, the backrest 3 abuts against the first rear limit baffle 8 to be limited when the backrest 3 rotates to the vertical state, and the backrest 3 abuts against the first front limit baffle 7 to be limited when the backrest 3 rotates to the horizontal state. When the backrest 3 needs to be seated, the backrest rotates around the first rotating support column 6, the first stop block protrusion 9 on the backrest 3 rotates along with the rotation, and when the backrest moves to the vertical state, the first stop block protrusion 9 abuts against the first rear limit baffle 8 to limit the position and cannot rotate any more, so that the function of the backrest 3 is realized; when needs crouch, back 3 is rotatory around first rotation support column 6, rotatory simultaneously, and first dog arch 9 on the back 3 also follows rotatory together, and when moving to the horizontality, first dog arch 9 supports and leans on first preceding limit baffle 7 to realize the function of sleeping with spacing unable continuation rotation again.

On the other hand, the first rotating support column 6 also functions to raise the backrest 3. The height of the traditional common seat is not enough, and the headrest 14 can not be installed, because the highest height of the headrest 14 of the automobile seat is not less than 750mm according to national standard.

Optionally, as shown in fig. 4 and 6, a second rotating support column 10 is arranged on the slide 5, a second front limit baffle 11 and a second rear limit baffle 12 are respectively arranged on two sides of the second rotating support column 10, the seat cushion 2 is hinged to the second rotating support column 10, when the seat cushion 2 rotates to a vertical state, the seat cushion 2 abuts against the second rear limit baffle 12 for limiting, and when the seat cushion 2 rotates to a horizontal state, the seat cushion 2 abuts against the second front limit baffle 11 for limiting. When sitting is needed, the slide seat 5 drives the cushion 2 to slide to the rearmost end along the slide rail 4, the cushion 2 is turned backwards to be in a horizontal state, and at the moment, the second stop protrusion 13 on the cushion 2 abuts against the second rear limit stop 12 to achieve limiting; when needs crouch, slide 5 drives cushion 2 and slides to foremost along slide rail 4, and cushion 2 is preceding 180 degrees to the horizontality backward, and at this moment, protruding 13 of second stop on the cushion 2 supports and leans on to realize spacingly by limit baffle 11 before the second.

Optionally, when the backrest 3 and the seat cushion 2 are both located at the horizontal limit position, the free end of the backrest 3 is abutted to one end of the seat cushion 2. When lying, the backrest 3 is abutted against the cushion 2, and the cushion 2 is prevented from sliding backwards.

Optionally, a headrest 14 is provided at the free end of the backrest 3. The headrest 14 serves for greater comfort when sitting. The headrest 14 can be inserted with the backrest 3, and when the user needs to lie down, the headrest 14 is taken down, and the backrest 3 is rotated, so that the tail end of the backrest 3 just abuts against and is stable with the seat cushion 2.

Optionally, the slide rail 4 is composed of two i-shaped steels arranged in parallel. Two tracks are more stable and firm.

Alternatively, the back surface of the backrest 3 is flat, and the area of the front surface of the backrest 3 near the lower part protrudes outwards to form a slope with the area near the head. The traditional seat back is turned over and laid flat successively to make a bed, but the seat back is flat, and the riding comfort is poor. Thus, this embodiment uses a flat back surface, so that when rotated and lowered, the bed is flat.

Optionally, the back of the seat cushion 2 is flat, and the area of the front of the seat cushion 2 near the inside is recessed downward to form a slope with the area near the outside. When lying, the back of the cushion 2 is flat, and forms a flat bed together with the flat back of the backrest, so that the user feels comfortable when lying. When the seat is standing, the area of the front surface of the seat cushion 2 close to the inner part is sunken downwards, namely the height of one end close to the backrest 3 is lower than that of the backrest 3, so that a person sits on the seat cushion 2 and has a posture of inclining backwards, and the person feels more comfortable.

Example two:

this embodiment includes the bench 100 of the first embodiment, and the detailed structure of the bench 100 is not described herein.

As shown in fig. 7 and 8, the car seat 200 further includes a seat 200 disposed opposite to the bench 100, and a backrest of the seat 200 is rotatable to a horizontal state and is at the same height as the seat cushion 2. When the user needs to sit, the backrest of the seat 200 is turned to be in a vertical state, and when the user needs to lie, the backrest is turned to be in a horizontal state, and the backrest, the seat cushion 2 and the backrest 3 are horizontally spliced together to form a bed.

Alternatively, when the backrest of the seat 200 is rotated to the horizontal state, the backrest abuts against the seat cushion 2. Seamless butt joint improves the comfort level of lying.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; the present invention can be smoothly implemented by those skilled in the art according to the drawings and the above description; however, those skilled in the art should understand that changes, modifications and variations made by the above-described technology can be made without departing from the scope of the present invention, and all such changes, modifications and variations are equivalent embodiments of the present invention; meanwhile, any changes, modifications, evolutions, etc. of the above embodiments, which are equivalent to the actual techniques of the present invention, still belong to the protection scope of the technical solution of the present invention.
