Description

Car seat storage system

Technical Field

The invention belongs to the technical field of automobile seats, and particularly relates to an automobile seat storage system.

Background

Passenger cars are generally designed to carry passengers and carry-on luggage, particularly minicars, which cannot carry items of a slightly larger size due to the smaller compartment space and trunk space. However, if the vehicle loading space is fully utilized, articles having a size within the size range of the entire vehicle loading space can be accommodated. However, in the prior art, the rear seats are mounted on the floor of the vehicle compartment, and the seat cushion is supported by the legs, so that the utilization rate of the space in the vehicle is still low even if the seat back is laid back or folded forward on the seat cushion.

In order to further improve the utilization rate of the space in the vehicle when loading articles, patent document CN102164774A discloses a folding seat system, which may include: a seat cushion configured to be pivotally coupled to a first portion of a body of a vehicle about a first axis of rotation; and a seat back configured to be pivotally coupled to a second portion of the vehicle body about a second axis of rotation; the seat back is detachably coupled to the seat cushion, and is disconnected from the seat cushion when stowed, and is rotated toward a side wall or a top wall of the vehicle compartment. Similarly, patent document CN209534807U discloses a seat comprising a seat cushion and a backrest which are separately provided, the seat cushion being connected with an inner bottom portion in a vehicle body, and the backrest being hingedly and/or slidably connected with an inner top portion in the vehicle body to switch the backrest between a reclining position and a stowing position; wherein, in the reclining position, the backrest is opposed to a rear side of the seat cushion and adapted to be reclined by an occupant seated on the seat cushion; in the stowed position, the resting surface of the backrest is opposite the interior roof or back of the front seat within the vehicle body to increase the available stowage space within the vehicle. These solutions all free up the space occupied by the seat back, but the space occupied by the seat cushion and the underlying support structure is still not used efficiently.

Disclosure of Invention

In view of the above, the present invention provides a vehicle seat stowing system capable of stowing a seat including a seat cushion and a backrest as a whole to a position close to a cabin wall, thereby increasing a vehicle interior loading space.

The technical scheme is as follows:

the automobile seat storage system comprises a seat arranged in a carriage, the seat comprises a seat cushion and a backrest, the lower part of the backrest is connected with the rear part of the seat cushion, the key point is that,

the seat has an operating position in which the seat is occupied by an occupant and a stowed position in which both the backrest and the seat cushion are adjacent a top wall of the vehicle compartment;

an adjusting device is arranged between the seat and the top wall of the carriage and is used for driving the seat to move between the working position and the accommodating position;

a supporting and locking assembly is arranged between the two sides of the seat cushion and the side wall or the floor of the carriage on the same side, so that the seat cushion is fixed when the seat is in the working position;

a lock mechanism for fixing the seat in the storage position is provided between the seat and an upper wall of the vehicle compartment or an upper portion of a side wall of the vehicle compartment.

Compared with the prior art, the invention has the beneficial effects that: after the seat is folded, the seat cushion and the space below the seat cushion are connected with the upper space into a whole, so that the seat cushion can be utilized, and the space for loading articles in the carriage is maximized.
