Description

Back row seat suitable for many practical scenes

Technical Field

The utility model relates to the technical field of seats, in particular to a rear seat suitable for multiple practical scenes.

Background

Current MPVs have three rows of seats and the market requires flexible changes in three rows of seating space and trunk space. The current MPV three-row seat can not well realize flexible conversion of three rows of riding spaces and trunk spaces. For example:

the secondary turnover mechanism of the car rear seat disclosed in Chinese patent application publication No. CN202193003U comprises a single seat and a double seat, wherein a hinge is arranged at the joint of a cushion framework and a backrest framework of the single seat or the double seat, and a hinge is arranged at the joint of the cushion framework and a carriage floor of the single seat or the double seat. The secondary folding mechanism for the rear-row seat of the car has the beneficial technical effects that the space of the car trunk is increased in the length direction and the height direction, so that the requirements for placing different articles are met, and the effective utilization space of the car trunk is increased. The double folding function is realized, and the sliding rail function is not improved.

The one-key turnover seat framework disclosed in Chinese patent application publication No. CN114179687A comprises a framework main body, a linkage mechanism and a turnover mechanism. The framework main body comprises a backrest framework, an angle adjuster and a cushion framework; one end of the linkage mechanism is connected with the backrest framework, and the other end of the linkage mechanism is connected with the floor lock so as to unlock the floor lock after a certain inclination angle occurs to the backrest framework; the turnover mechanism comprises a front mounting foot and a floor lock, wherein the front mounting foot is arranged on one side of the cushion framework, and the floor lock is arranged on one side, far away from the front mounting foot, of the cushion framework, so that the cushion framework turns over to one side of the front mounting foot after the floor lock is unlocked. The one-key turnover seat framework is connected with the backrest framework and the turnover mechanism, and when the backrest framework inclines at a certain angle, the turnover mechanism can be started to unlock the seat for turnover, so that the operation is simple, the assembly efficiency is improved, and the problem that passengers in the rear row get in and out is solved conveniently. The double folding function is realized, but the sliding rail function is not realized.

Published Chinese patent application publication No. CN104108321ASeating arrangementThe rail cover is formed to cover at least a region of the floor panel corresponding to a lower edge of the door opening and to cover a region that spans between the pair of slide rails in a state in which the seat is in the storage posture. This patent protection is the shroud on the slide rail, and the technical problem that it solved is: because the sliding guide rail is arranged on the bottom plate, when the seat moves to the front through the sliding rail, the sliding rail can block the pain point of the person.

A vehicle seating system disclosed in chinese patent application publication No. CN1412039a, comprising: a first row of seats as driver seats; a second row of seats positioned at the rear of the first row of seats and provided with a seat and a chair back, wherein the chair back of the second row of seats can be folded on the seat; and a third row seat provided at a rear portion of the second row seat, the third row seat being movable forward in a state in which the seat back is folded onto the seat cushion, and being storable in a space immediately below the second row seat; the method is characterized in that: the second-row seat can slide and tilt in the vehicle longitudinal direction even when the second-row seat is returned to a position above the third-row seat in the folded storage state, and both the seat back and the seat back of the second-row seat can be flipped up forward. The emphasis of this patent is on how to stow the three rows of seats under the two rows of seats.

The underbody panel disclosed in chinese patent application publication No. CN107031739a has: a2 nd row seat provided so that the seat cushions of the divided seats divided in the left-right width ratio can be folded about the front rotation axes, respectively; and a 3 rd row seat of a double seat. The 2 nd row seat has a rear attachment/detachment portion that enables the rear portion of the 2 nd row seat to be detached from the floor or attached to the floor. The rear attaching/detaching portions of the 6-split-side seat are disposed on the right rear frame and the reinforcement, respectively, which protrude upward of the floor panel and are located at the center in the lateral direction. The rear attaching/detaching portions of the seat on the 4-split side are respectively disposed on the rear frame on the left side and the reinforcement member that protrudes upward from the floor panel and is offset from the reinforcement member in the center toward the rear frame side on the left side. Accordingly, a foot space for an occupant seated in the rear seat is ensured. The problem addressed by this patent is to provide a vehicle body floor structure capable of ensuring a foot placing space of an occupant seated in a rear seat.

In a seat which is provided in a state in which the seat is folded and can be lifted from the rear side to the upper side, a striker lock is provided in a manner in which the striker lock is fixedly attached to the lower portion of the lower rail near the rear end of the seat, and the striker lock is not unlocked by an operating lever when the seat is held in a forward riding position, and a switching mechanism for performing an unlocking operation of the striker lock by the operating lever when the seat is moved to a predetermined rear position is provided in the seat which is provided in a state in which the striker lock is lifted from the rear side to the upper side, and the order in which the seat is lifted from the movement of the seat to the rear specific position in the vehicle is ensured from the mechanism. The seat of this patent, although being able to be flipped over twice and having a track, is not able to move with the track after the seat has been flipped over twice and the track has been flipped over together.
