A child seat for transporting infants or toddlers generally in a half-lying, half-sitting position in a car, the seat comprising:

• a seat surface;
• a backrest inclined shallowly relative to said seat surface, said backrest provided with an unchangeable portion and an extendable portion, a length of said backrest being adapted to be varied by a guided parallel shift of the extendable portion relative to said seat surface, such that a middle area of an upper edge of the extendable portion, in at least one state of operation, projects over the unchangeable portion of said backrest in a direction of travel of the car;
• wherein the guided parallel shift follows generally a direction of a spine of a child seat occupant and is adapted to be accomplished when the child seat occupant is seated in the child seat and/or when the child seat is fastened on a seat of the car;
• wherein the guided parallel shift is along a straight line which is inclined by a constant angle α against a horizontal plane, rising in the direction of travel of the car;
• wherein the extendable portion of said backrest is provided with upper lateral body rests for substantially guiding shoulders and/or upper arms of the child seat occupants;
• said backrest having at least one guide member located at a rear backrest outer face for receiving and guiding a portion of a safety belt proper to the car;
• and
• wherein the upper edge of the extendable portion of said backrest in any extended position and in the direction of travel, protrudes in front of an upper edge of the unchangeable portion of said backrest.

A child seat for transporting infants or toddlers generally in a half-lying, half-sitting position in a car, the seat comprising:

• a seat surface;
• a backrest inclined shallowly relative to said seat surface, said backrest having an unchangeable portion and extendable portion, a length of said backrest adapted to be varied by a guided parallel shift of the extendable portion relative to said seat surface, such that a middle area of an upper edge of the extendable portion, in at least on state of operation, projects over the unchangeable portion of said backrest in a direction of travel of the car;
• wherein the guided parallel shift follows essentially a direction of a spine of a child seat occupant and is adapted to be varied when the child seat occupant is seated in the child seat and/or when the child seat is fastened on a seat of the car;
• wherein the guided parallel shift is along a straight line which is inclined by a constant angle α against a horizontal plane, rising in the direction of travel of the car;
• wherein the extendable portion of said backrest is provided with upper lateral body rests for substantially guiding shoulders and/or upper arms and/or a head of the child seat occupant;
• and
• wherein each of the upper lateral body rests is divided by a step, respectively, into an upper area which is provided as a lateral headrest, and a lower area, which is provided as a lateral arm and/or shoulder rest;
• said backrest having at least one guide member located at a rear backrest outer face for receiving and guiding a portion of a safety belt proper to the car,
• wherein, at a maximum extended position of the extendable portion of said back-rest, in which the extendable portion of said backrest is displaced along a straight line for a maximum displacement dmax from an entirely slid-in position, the middle area of the upper edge of the extendable portion lies, in the direction of travel, substantially in front of a middle area of an upper edge of the unchangeable portion of said backrest, by a horizontal distance h of equal or more than 0.7 times dmax:h≧0.7*dmax in front of the upper edge of the unchangeable portion of the backrest, by a horizontal distance h of h=dmax*cosα.

A child seat for transporting infants or toddlers in a generally half-lying, half-sitting position in a car, the seat comprising:

• a seat surface;
• a backrest inclined shallowly relative to said seat surface, said backrest having an unchangeable portion and an extendable portion, a length of said backrest being adapted to be varied by a guided parallel shift of the extendable portion relative said seat surface, such that a middle area of an upper edge of the extendable portion, in at least one state of operation, projects over the unchangeable portion of said backrest in a direction of travel of the car;
• wherein the guided parallel shift follows substantially a direction of a spine of a child seat occupant and is adapted to be operative when the child seat occupant is seated in the child seat and/or when the child seat is fastened on a seat of the car;
• wherein the guided parallel shift is along a straight line which is inclined by a constant angle α against a horizontal plane, rising in a direction of travel of the car;
• wherein the extendable part of said backrest is provided with upper lateral body rests for substantially guiding shoulders and/or upper arms and/or a head of the child seat occupant;
• and
• wherein each of the upper lateral body rests is divided by a step into an upper area which comprises a lateral headrest, and a lower area, which comprises a lateral arm and/or shoulder rest;
• and
• said backrest having at least one guide member located at a rear backrest outer face for receiving and guiding a portion of a safety belt proper to the car;
• wherein the upper edge of the extendable part of said backrest in any extended position and in the direction of travel, protrudes in front of the upper edge of the unchangeable portion of said backrest.
