reclining at an attempt to recline said backrest (11) when said
seat means (1A) takes a position other than said transverse
state.
Claim 7
Dependent Claim
124 words
The vehicular child safety seat according to claim
6, wherein said backrest inclination limit means includes an engagement projection (11e) provided at a neighborhood

said support plate (30), said concave groove (30a, 30b) extending in the
transverse direction for receiving said engagement
projection (11e) so that said backrest (11) is reclined when said
seat means is at the transverse state, and said abutment
face preventing the reclining of said backrest by abutting
against said engagement projection (11e) at an attempt to
recline said backrest (11) when said seat means (1A) takes a
position other than said transverse state .
Claim 8
Dependent Claim
43 words
The vehicular child safety seat according to claim
7, wherein said engagement projection (11e) is accepted in said
