Abstract
Abstract A cushion structure for a nursing equipment includes a soft third cushion layer of which member has low density, hard second and fourth cushion layers (5b, 5d) of which members have high density provided on opposing sides of the third cushion layer, and soft first and fifth cushion layers (5a, 5e) of which members have low density. The third cushion layer (5b) has an air pool (51), and outlet holes (52, 53) are provided in the second and fifth cushion layers (5b, 5d) at positions apart from the center of air pool (51) and offset from each other. Thus a cushion structure for a nursing equipment which can protect the head (brain) of an infant by effectively absorbing shock can be provided.

infant from behind, comprising: a first cushion layer (5b); a second cushion layer (5c) positioned behind said first cushion layer
(5b); and a third cushion layer (5d) positioned behind said second cushion
layer (5c), wherein said second cushion layer (5c) has an air pool (51) consisting of a
prescribed space.
Claim 7
Dependent Claim
38 words
The cushion structure for a nursing equipment according to
claim 6, wherein density of a member constituting said second cushion
layer (5c) is lower than density of a member constituting said first and
third cushion layers (5b, 5d).
Claim 8
Dependent Claim
28 words
The cushion structure for a nursing equipment according to
claim 6, wherein said second cushion layer (5c) is softer than said first and
third cushion layers (5b, 5d).
Claim 9
Dependent Claim
36 words
The cushion structure for a nursing equipment according to
claim 6, wherein at least one of said first and third cushion layers
(5b, 5d) has an outlet hole (52, 53) communicated with said air pool (51).
Claim 10
Dependent Claim
32 words
The cushion structure for a nursing equipment according to
claim 9, wherein said outlet hole (52, 53) is provided at a position apart
from a central region of said air pool (51).
Claim 11
Dependent Claim
71 words
The cushion structure for a nursing equipment according to
claim 6, wherein said first and third cushion layers (5b, 5d) have outlet
holes (52, 53) communicated with said air pool (51), said outlet holes (52,
53) being provided at positions apart from a central region of said air pool
(51) and said outlet holes (52, 53) provided in said first and third cushion
layers (5b, 5d) being offset from each other.
Claim 12
Dependent Claim
34 words
The cushion structure for a nursing equipment according to
claim 6, further comprising a fourth cushion layer (5a) softer than said first
cushion layer on a front surface of said first cushion layer (5b).
Claim 13
Dependent Claim
52 words
The cushion structure for a nursing equipment according to
claim 12, further comprising a fifth cushion layer (5e) on a back surface
side of said third cushion layer (5d), density of a member constituting said
fifth cushion layer (5e) being lower than density of a member constituting
said third cushion layer (5d).
Claim 14
Dependent Claim

Claim 17
Dependent Claim
48 words
A shock absorbing structure for use in apparatus in or on which a baby
