TECHNICAL FIELD OF THE INVENTION
The present invention relates to a stroller, and more particularly, to a stroller provided with a cushion sheet formed by a cushioning member.
[0002]
[Prior art]
Various devices have been devised for the stroller so that the infant accommodated in the infant seat can comfortably spend. For example, riding comfort is improved by forming a baby seat in which a baby is directly accommodated by a member having excellent cushioning properties (cushioning member).
[0003]
[Problems to be solved by the invention]
As described above, the infant seat is generally formed of a soft member having excellent cushioning properties so that the infant can spend comfortably.
[0004]
However, the infant sheet formed by such a member is easily bent and wrinkled. In particular, in recent years, strollers equipped with a reclining mechanism that can arbitrarily change the inclination angle of the body of the baby seat, and strollers equipped with a folding mechanism that allows the stroller to be compactly folded when carried. In addition, a stroller provided with a deformable infant seat is widely used. In such a stroller, bending and wrinkling are particularly likely to occur.
[0005]
On the other hand, in strollers in recent years in which the pursuit of further comfort is demanded, members that are softer and more comfortable than ever are used for infant seats, but such members have relatively low restoring force. Is scarce. For this reason, it is very difficult to recover the bends and wrinkles once generated in the infant sheet.
[0006]
Accordingly, the infant sheet having such a bent or wrinkled body loses its volume and loses its overall balance. For this reason, such a baby seat tends to have a poor ride comfort, and also has a poor external appearance.
[0007]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a stroller capable of effectively recovering a bend or wrinkle generated in an infant sheet.
[0008]
[Means for Solving the Problems]
The present invention includes a stroller body having a pushrod, a front leg, and a rear leg, and a cushion seat installed on the stroller body, having a body and a seat, and formed by a cushioning member, The stroller is characterized in that an elastic body is embedded in at least a part of the cushion sheet. The cushioning member means all members having excellent cushioning properties.
[0009]
In this case, it is preferable that the cushion sheet has a central portion and side portions disposed on the left and right of the central portion, and the elastic body is embedded in the side portion of the cushion sheet. .
[0010]
Further, it is preferable that the elastic body is embedded near a boundary between the body and the seat.
[0011]
Preferably, the elastic body is embedded in the seat.
[0012]
Further, it is preferable that a folding mechanism for folding the stroller is further provided, and the elastic body is embedded in a portion of the cushion sheet that is folded when the stroller is folded by the folding mechanism.
[0013]
Preferably, the elastic body includes a plastic member.
