An infant stroller apparatus includes a rear leg frame including a first side segment, a handle having a second side segment formed by at least a first and a second tubular member telescopically assembled with each other, an impeding part assembled with the second side segment and operable to create an interference that blocks retraction of the second tubular member into the first tubular member, and an armrest pivotally connected with the second side segment and provided with an actuating member disposed adjacent to the impeding part. A rotation of the armrest in a direction for collapsing the infant stroller apparatus can cause a displacement of the actuating member, which drives the impeding part in movement to remove the interference and allow retraction of the second tubular member into the first tubular member.

1. An infant stroller apparatus comprising: a rear leg frame including a first side segment;a handle having a second side segment formed by at least a first and a second tubular member telescopically assembled with each other;an impeding part assembled with the second side segment and operable to create an interference that blocks retraction of the second tubular member into the first tubular member; andan armrest pivotally connected with the second side segment and provided with an actuating member disposed adjacent to the impeding part, wherein a rotation of the armrest in a direction for collapsing the infant stroller apparatus causes a displacement of the actuating member, which drives the impeding part in movement to remove the interference and allow retraction of the second tubular member into the first tubular member. 2. The infant stroller apparatus according to claim 1, wherein the impeding part is pivotally assembled with the second side segment. 3. The infant stroller apparatus according to claim 1, wherein the impeding part is operable to abut against an end portion of the second tubular member to block retraction of the second tubular member into the first tubular member. 4. The infant stroller apparatus according to claim 3, wherein the impeding part is pivotally connected with the first tubular member about a pivot axis, and the actuating member pushes against a region of the impeding part spaced apart from the pivot axis to push the impeding part in rotation about the pivot axis for removing the interference that blocks retraction of the second tubular member into the first tubular member. 5. The infant stroller according to claim 3, wherein the impeding part is pivotally connected with the first tubular member about a pivot axis, and is connected with a spring structure operable to bias the impeding part to a position for abutting against the end portion of the second tubular member. 6. The infant stroller apparatus according to claim 5, wherein the spring structure is formed integrally with the impeding part. 7. The infant stroller apparatus according to claim 5, wherein the spring structure has an elongated shape that is connected with the impeding part and has a distal end connected with the first tubular member. 8. The infant stroller apparatus according to claim 5, wherein the actuating member rotates along with the armrest to push the impeding part in rotation for removing the interference that blocks retraction of the second tubular member into the first tubular member, and to cause elastic deflection of the spring structure. 9. The infant stroller apparatus according to claim 8, wherein the spring structure includes a protrusion, and the elastic deflection of the spring structure displaces the protrusion to a position adapted to interact with the end portion of the second tubular member to retain the second tubular member in a retracted state. 10. The infant stroller apparatus according to claim 1, wherein the armrest is pivotally connected with the first tubular member about a first pivot axis, the impeding part is pivotally assembled with the first tubular member about a second pivot axis spaced apart from the first pivot axis, and the actuating member rotates along with the armrest about the first pivot axis to push the impeding part in rotation about the second pivot axis for removing the interference that blocks retraction of the second tubular member into the first tubular member. 11. The infant stroller apparatus according to claim 10, wherein the actuating member has a cam-shaped rib. 12. The infant stroller apparatus according to claim 11, wherein the impeding part includes a protrusion that projects through an opening of the first tubular member, and the cam-shaped rib rotates along with the armrest about the first pivot axis to push against the protrusion to cause rotation of the impeding part for removing the interference that blocks retraction of the second tubular member into the first tubular member. 13. An apparatus for seating a child, comprising: a first frame portion including a first side segment;a second frame portion having a second side segment formed by at least a first and a second tubular member telescopically assembled with each other;an impeding part pivotally assembled with the second side segment about a first pivot axis and operable to create an interference that blocks retraction of the second tubular member into the first tubular member; anda third frame portion pivotally connected with the second side segment about a second pivot axis and affixed with an actuating member disposed adjacent to the impeding part, wherein a rotation of the third frame portion in a direction for collapsing the apparatus causes a rotation of the actuating member, which drives the impeding part to rotate about the first pivot axis to remove the interference and allow retraction of the second tubular member into the first tubular member. 14. The apparatus according to claim 13, wherein the impeding part is operable to abut against an end portion of the second tubular member to block retraction of the second tubular member into the first tubular member. 15. The apparatus according to claim 14, wherein the impeding part is pivotally connected with the first tubular member, and the actuating member pushes against a region of the impeding part spaced apart from the first pivot axis to push the impeding part in rotation about the first pivot axis for removing the interference that blocks retraction of the second tubular member into the first tubular member. 16. The apparatus according to claim 14, wherein the impeding part is pivotally connected with the first tubular member, and is connected with a spring structure operable to bias the impeding part to a position for abutting against the end portion of the second tubular member. 17. The apparatus according to claim 16, wherein the spring structure is formed integrally with the impeding part. 18. The apparatus according to claim 16, wherein the spring structure has an elongated shape that is connected with the impeding part and has a distal end connected with the first tubular member. 19. The apparatus according to claim 16, wherein the actuating member rotates along with the third frame portion to push the impeding part in rotation for removing the interference that blocks retraction of the second tubular member into the first tubular member, and to cause elastic deflection of the spring structure. 20. The apparatus according to claim 19, wherein the spring structure includes a protrusion, and the elastic deflection of the spring structure displaces the protrusion to a position adapted to interact with the end portion of the second tubular member to retain the second tubular member in a retracted state. 21. The apparatus according to claim 13, wherein the actuating member has a cam-shaped rib. 22. The apparatus according to claim 21, wherein the impeding part includes a protrusion that projects through an opening of the first tubular member, and the cam-shaped rib rotates along with the third frame portion about the second pivot axis to push against the protrusion, which causes rotation of the impeding part about the first pivot axis for removing the interference that blocks retraction of the second tubular member into the first tubular member.
