Description

Technical Field

[0001] The utility model relates to the field of automobile seats, in particular to an automobile seat that can be flattened and transformed into a bed. Background Art

[0002] Car seats can be categorized by shape as split or bench seats; by function as fixed, removable, or adjustable; and by the number of passengers, as single, double, or multi-seater seats. Based on their performance, they have evolved from the earliest fixed seats to multifunctional power-adjustable seats, including air-cushioned seats, electric seats, stereo seats, recovery seats, and even electronically adjustable seats. Material types include leather and velvet. There are also seats designed for specialized uses, such as child seats and racing seats. To enhance the practicality of car seats, some car seats can be converted flat into beds, with adjustable backrest angles, reversible seat cushions, and removable headrests. However, converting seats into beds is cumbersome and difficult. To convert, the seat cushions must be adjusted to flatten the seat before the backrest is flattened. This makes it difficult to level the backrest and seat cushions, resulting in inconsistent operation and limited space. Comparable products are also oversized.

[0003] Therefore, those skilled in the art provide a car seat that can be flattened into a bed to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the present utility model is to provide a car seat that can be flattened to become a bed, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The auxiliary backrest body is mounted on the seat cushion frame, and the backrest body is mounted on the auxiliary backrest frame, and the auxiliary backrest body is mounted on the auxiliary backrest frame, and the backrest frame body is connected to the auxiliary backrest frame body by a hinge. The backrest frame body is connected to the seat cushion frame by a hinge. Both the backrest frame body and the auxiliary backrest frame are connected at two right angles to the end of the seat cushion frame away from the backrest body. Ball heads and ball sockets are provided between the auxiliary backrest body and the side panels of the seat main frame. Gas springs are provided between the auxiliary backrest body and the side panels of the seat main frame. Main slide rails are installed in the channel steel on both sides of the seat main frame. A forward and backward moving slide rail is fixedly provided at the lower position of the seat main frame, and a forward and backward moving locking rod is provided between the two forward and backward moving slide rails.

[0007] As a further solution of the present invention: a headrest tube is fixedly provided on the connection end of the backrest body near the auxiliary backrest body. The headrest tube is a square hollow tube structure with an installation slot. The headrest tube is provided in two groups, each group is provided with two. The headrest body is plugged and installed in the headrest tube and limited by the installation slot to facilitate disassembly and installation of the headrest body.

[0008] As a further solution of the present invention: a seat belt outlet bracket is fixedly provided at the connection gap between the backrest frame body and the auxiliary backrest frame body, and a seat belt outlet seat is fixedly installed on the seat belt outlet bracket for installing the seat belt.

[0009] As a further solution of the present invention: two seat belt outlet brackets are provided, and seat belt welding pieces are correspondingly provided at the lower positions of the two seat belt outlet brackets.

[0010] As a further solution of the present invention: plastic guard plates 1 are provided on both side edges of the connection between the backrest body and the seat cushion body, and plastic guard plates 2 are provided on both side edges of the connection between the auxiliary backrest body and the seat cushion body, for protecting the connection positions.

[0011] As a further solution of the present invention: sawtooth structures are provided on both sides below the seat cushion frame, and matching grooves are provided at positions corresponding to the sawtooth structures on the main seat frame, and sinks corresponding to the sawtooth structures are provided in the matching grooves.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The seat-to-bed transformation in the utility model is continuous. You only need to move the seat cushion forward to realize the transformation into a flat bed, which is easier to operate and increases the space after the seat is transformed into a bed. The backrest is linked to the auxiliary backrest, so that the bed length can reach 1.8 meters after transformation, which can better meet the customer's demand for a large space. The seat size is personalized. The seat width direction uses pipes instead of stamping parts, so the seat width can be customized according to the customer and can be customized to any size.

[0014] 2. The utility model uses a screw with a hinged hole instead of a recliner to realize the seat cushion flipping function, which can save a pair of recliners compared with the traditional reversing seat. The use of standard parts instead of purchased parts can greatly save the cost of raw materials. An air spring is added between the auxiliary backrest and the side panel of the chassis to make the bed conversion process continuous. The preload force can be increased in the initial position to prevent the seat from going straight up and down when converting into a bed, which may damage the seat. The seat can be locked during the flattening process to allow the passenger to lie back comfortably on the seat. BRIEF DESCRIPTION OF THE DRAWINGS
