Through the two limit blocks 32 respectively matching with the two sets of limit grooves 13, on one hand, when the lumbar pad body 2 is pulled to adjust the angle, the clamping force between the two limit blocks 32 and the limit grooves 13 needs to be overcome twice, that is, under the condition of the same other conditions, the force needed for pulling the lumbar pad body 2 is doubled, so that the angle of the lumbar pad body 2 cannot be easily changed when a child backs the lumbar pad body, and the stability is higher; on the other hand, the connecting strength between the mounting part 3 and the heightening pad body 1 is also improved, which is favorable for prolonging the service life thereof. As shown in fig. 8, in order to increase the strength of the stopper groove 13, a reinforcing rib 14 is provided between the stopper groove 13 and the heightening pad body 1.

Referring to fig. 3 and 6, in some embodiments of the present application, a latch 31 is located at an upper end of the mounting member 3, and a stopper 32 is located below the latch 31. When the waist pad body 2 is pulled to adjust the angle of the waist pad body 2, the waist pad body 2 and the mounting piece 3 rotate around the rotation axis of the bolt 31; that is, as the latch 31 is closer to the upper end of the installation member 3, the distance from the upper end of the lumbar pad body 2 to the latch 31 is shorter (i.e., the moment arm for pulling the lumbar pad body 2 is shorter), and the power required for pulling the lumbar pad body 2 is larger under the same other conditions. To sum up, when bolt 31 is located the upper end of installed part 3, can improve and pull the required dynamics of bustle body 2 for children can not make bustle body 2's angle change easily when the back, and stability is higher. In addition, when the bolt 31 is positioned at the upper end of the mounting piece 3, the whole mounting piece 3 is hidden in the heightening pad body 1, and the appearance is more attractive.
