Abstract
Abstract A child seat has an upper base section ( 1 ) and a lower base section ( 201 ) for changing an inclination angle between these base sections. The upper base section 1 and the lower base section ( 201 ) are journaled rotatably about a common journal axis ( 201 A) at the front portion of the base. At a rear end side, an inclination angle changing mechanism ( 200 ) is installed for adjusting a spacing between the upper base section ( 1 ) and the lower base section ( 201 ) opposite the journal axis ( 201 A). This structure provides a child seat allowing adjustment of the angle of inclination of a support surface supporting a child even if the child supporting surface extends lengthwise of a passenger car seat to which the base formed by the two base sections 1 and 201 , is attached. This leveling of the child supporting surface is possible if the child seat ( 2 ) is rotatable about a vertical axis relative to its base.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
313 words
A child seat and seat base combination, comprising seat elements ( 2 , 3 , 4 ) forming a seat including a child support surface ( 3 , 4 ) for supporting a child, a seat base ( 1 , 201 ) supporting said seat elements ( 2 , 3 , 4 ), first means for rotating said seat elements including said child support surface ( 3 , 4 ) relative to said seat base about an axis extending normal to said seat base ( 1 , 201 ), and second means ( 200 ) operatively positioned for adjusting an inclination angle between said seat base and said child support surface ( 3 , 4 ) for leveling said child support surface independently of any slanting position of said seat base relative to a horizontal plane and wherein said seat base comprises an upper base section ( 1 ) rotatably carrying said seat elements ( 2 , 3 , 4 ) and a lower base section ( 201 ) for positioning said child seat and said seat base on a placing surface, wherein said second means ( 200 ) for adjusting an inclination angle are operatively connected between said upper base section ( 1 ) and said lower base section ( 201 ), and further comprising a journal axis ( 201 A) journaling said upper base section ( 1 ) to said lower base section ( 201 ), whereby said upper base section ( 1 ), which rotatably carries said seat elements including said support surface ( 3 , 4 ), is adjustable in its angular position relative to said lower base section ( 201 ) by adjusting said second means ( 200 ) for increasing or decreasing a spacing between said upper base section ( 1 ) and said lower base section ( 201 ) opposite said journal axis ( 201 A).
Claim 2
Dependent Claim
313 words
A child seat and seat base combination, comprising seat elements ( 2 , 3 , 4 ) forming a seat including a child support surface ( 3 , 4 ) for supporting a child, a seat base ( 1 , 201 ) supporting said seat elements ( 2 , 3 , 4 ), first means for rotating said seat elements including said child support surface ( 3 , 4 ) relative to said seat base about an axis extending normal to said seat base ( 1 , 201 ), and second means ( 200 ) operatively positioned for adjusting an inclination angle between said seat base and said child support surface ( 3 , 4 ) for leveling said child support surface independently of any slanting position of said seat base relative to a horizontal plane and wherein said seat base comprises an upper base section ( 1 ) rotatably carrying said seat elements ( 2 , 3 , 4 ) and a lower base section ( 201 ) for positioning said child seat and said seat base on a placing surface, wherein said second means ( 200 ) for adjusting an inclination angle are operatively connected between said upper base section ( 1 ) and said lower base section ( 201 ), and further comprising a journal axis ( 201 A) journaling said upper base section ( 1 ) to said lower base section ( 201 ), whereby said upper base section ( 1 ), which rotatably carries said seat elements including said support surface ( 3 , 4 ), is adjustable in its angular position relative to said lower base section ( 201 ) by adjusting said second means ( 200 ) for increasing or decreasing a spacing between said upper base section ( 1 ) and said lower base section ( 201 ) opposite said journal axis ( 201 A).
Claim 3
Dependent Claim
40 words
The combination of claim 1 , wherein said seat elements include a seat ( 3 ) and a back rest ( 4 ), and wherein said back rest ( 4 ) is reclinable relative to said seat ( 3 ).
Claim 4
Dependent Claim
83 words
The combination of claim 1 , wherein said upper base section ( 1 ) comprises a seat belt engagement wall portion which tightens a vehicle seat belt contacting said seat belt engagement wall portion when said spacing between said upper base section ( 1 ) and said lower base section ( 201 ) is increased by said second means ( 200 ) for adjusting said inclination angle between said upper base section ( 1 ) and said lower base section ( 201 ).
Claim 5
Dependent Claim
52 words
The combination of claim 1 , further comprising an inclination angle indicator ( 300 ) connected to any one of said seat elements or said upper base section ( 1 ), said indicator ( 300 ) changing its position when said inclination angle is adjusted by said second means ( 200 ).
Claim 6
Dependent Claim
96 words
The combination of claim 4 , wherein said inclination angle indicator ( 300 ) comprises range indicator elements (A 1 , A 2 , A 3 ) positioned for indicating a current status of said seat elements as a chair or a bed, and wherein said indicator elements comprise a first indicator element (A 1 ) for indicating a leveling range of said child support surface, and second and third indicator elements (A 2 , A 3 ) for indicating an inclination of one of said seat elements relative to a normal to a horizontal plane.
Claim 7
Dependent Claim
27 words
The combination of claim 5 , wherein said first indicator element (A) is positioned between said second and third indicator elements, (A 2 and A 3 ).
