Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the specific embodiments.

See fig. 1-9 for an elevated seat having an expanded state and a collapsed state. The booster seat comprises a seat 1 and a backrest 2, and an armrest assembly 3.

The seat 1 includes a seat body 11, and two sets of side supports 12 provided on both left and right sides of the seat body 11, the side supports 12 being rotatably connected to outer portions of the seat body 11 in the left-right direction by first shafts 13, and axial lines of the first shafts 13 extending in the front-rear direction.

The backrest 2 comprises a backrest connecting rod 22 and two groups of backrest rods 21 respectively arranged at the left side and the right side of the backrest connecting rod 22, the backrest rods 22 extend along the left-right direction, the upper parts of the backrest rods 21 are rotatably connected to the end parts of the backrest connecting rod 22 through a second shaft 23, the backrest connecting rod 22 and the backrest rods 21 at the two sides form a U-shaped backrest 2 with a downward opening together, and the lower parts of the backrest rods 21 are rotatably connected to the rear parts of the side bearings 12 at the same side through a third shaft 4.

The armrest assembly 3 has two sets disposed on the left and right sides, and on each of the left and right sides of the booster seat, the armrest assembly 3 is rotatably connected between the side support 12 and the back lever 21. In the present embodiment, the handle assembly 3 includes a first handle bar 31 extending in the front-rear direction and a second handle bar 32 extending in the up-down direction, a rear portion of the first handle bar 31 is rotatably connected to the back support bar 21 through a fourth shaft 5, a front portion of the first handle bar 31 is rotatably connected to an upper portion of the second handle bar 32 through a fifth shaft 6, a lower portion of the second handle bar 32 is rotatably connected to the side support 12 through a sixth shaft 7, and the sixth shaft 7 is located in front of the third shaft 4 on the side support 12. Thus, a four-bar linkage is formed among the first grab bar 31, the second grab bar 32, the back lever 21, and the side bolster 12.

More specifically, referring to the drawings, the seat 1 is located between two sets of the armrest assemblies 3 and two sets of the back levers 21 in the left-right direction, and the back levers 21 and the armrest assemblies 3 are connected to the outer side portions of the side supports 12. The length of the back lever 21 extending in the up-down direction is longer than the length of the seat 1 extending in the front-rear direction.

The side support 12 includes a support portion 12a extending horizontally and an extension portion 12b extending outward and downward from an outer side portion of the support portion 12a, an inner side portion of the support portion 12a is rotatably connected to the seat main body 11 by a first shaft 13, and the seat main body 11 and the support portions 12a on both sides form a seating area for seating a child in a deployed state. The lower part of the second handrail rod 32 in the handrail assembly 3 is rotatably connected to the outside of the extension part 12b, and the lower part of the back rest rod 21 is also rotatably connected to the outside of the extension part 12 b.

The booster seat also includes a locking mechanism for locking it in the deployed condition. In the present embodiment, the locking mechanism includes a locking member (not shown) provided between the lower portion of the back lever 21 and the rear portion of the side support 12 for locking the two relative to each other.

Referring to fig. 1 to 3, in the unfolded state of the booster seat, the seat 1 is unfolded in the left-right direction for sitting and standing, which has a wide space of a sitting area, the backrest 2 is erected at the rear of the seat 1 for leaning, and the first and second bars 31 and 32 of the armrest assembly 3 are unfolded opposite to each other and provide protection to the left and right sides of the seat 1. In this state, the axial lines of the first shaft 13 and the second shaft 23 extend in different directions.

When the booster seat needs to be folded, the backrest 2 is driven to turn forward to rotate and fold relative to the seat 1, the first handrail rod 31 and the second handrail rod 32 of the handrail assembly 3 are driven to fold relative to each other, so that the backrest rod 21, the side supporting member 12 and the handrail assembly 3 on the same side are mutually folded, and one-time folding of the booster seat is completed. After the one-time folding, the back lever 21 and the first and second rest levers 31 and 32 of the armrest assembly 3 are folded toward each other and positioned outside the side bolster 12, and the back link 22 is positioned in front of the seat 1. At this time, on each of the left and right sides, the axis of the first shaft 13 and the axis of the second shaft 23 extend parallel to or collinear with each other, here extending collinear, as shown in fig. 4 to 6.

Next, referring to fig. 7, the back lever 21, the side supports 12, and the armrest assembly 3, which are folded at both sides, are turned in the left-right direction around the first shaft 13 and the second shaft 23, so that the booster seat can be folded twice. After the last secondary folding, the two extending parts 12b on the left and right sides of the seat 1 are turned in opposite directions and are located below the seat main body 11, the upper surface of the supporting part 12a is turned to face outward, the backrest rod 21 and the armrest assembly 3 are folded mutually and are located below the extending parts 12b, the width after folding is only the width of the seat main body 11, and the structure shown in fig. 8 and 9 is formed after folding.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
