Abstract

The pushchair chassis is constructed axle-less so that each running wheel of wheel pair is mounted on suspension in the fashion of a shock absorber. The suspension has a guide tube (20) installed rigidly on the chassis and a bearing component (13) containing the mounting for the wheel in such a way that the bearing component can execute damped movement in relation to the guide tube by means of at least one helical spring (18,19). Between the guide tube and bearing component a protective tube (21) formed by two half-shells encloses the helical spring.
