Task: Translation
Input (Czech): Prední záves sedadla (1) automobilu, opatreného sklopným operadlem (3) má vodorovný prícný válcový cep (17) pevne spojený s podlahou (28) a vidlici (5) pevne spojenou se sedadlem (1) a nasazenou otocne a posuvne na cepu (17). Vidlice (5) má vpred otevrenou šterbinu (7) a zajištovací zarízení (8) pro zajištení vidlice (5) proti jejímu sejmutí z cepu (17), pricemž rovina (7´) soumernosti šterbiny (7) je ve vodorovné poloze sedadla v podstate vodorovná. Cep (17) je po své délce mimo krajní polohy posunutí vidlice (5) opatren radiálním hrebenem (18). Ve vodorovné poloze sedadla (1) svírá rovina (18´) soumernosti hrebene (18) s rovinou (7´) soumernosti šterbiny (7) takový úhel (.alfa.), že po vyklopení sedadla (1) vpred z vodorovné polohy kolem osy (27) cepu (17) o tento úhel (.alfa.) leží težište sedadla (1) se sklopeným operadlem (3) ve svislé rovine (200) v níž leží osa (27) cepu (17) nebo pred touto rovinou.
Output (English): The invented front suspension of a car seat (1) provided with a foldable backrest (3) has its horizontal transverse cylindrical pin (17) fixedly coupled with a floor (28), while its fork (5) being fixedly coupled to the seat (1) is rotatably and slidably mounted on the pin (17). The fork (5) has a forward open gap (7) and a securing device (8) for securing the fork (5) against its removal from the pin (17), wherein a plane of symmetry (7?) of the gap (7) is substantially horizontal when the seat is positioned in horizontal position. The pin (17) is provided all over its length, except for extreme positions of the fork (5) shift, with a radial rack (18). In horizontal position of the seat (1), a plane of symmetry (18?) of the rack (18) forms with the gap (7) plane of symmetry (7?) such an angle ({alpha}) that after tilting the seat (1) from its horizontal position forward about the axis (27) of the pin (17) by this angle ({alpha}), the center of gravity of the seat (1) with folded backrest (3) lies in vertical plane (200) in which lies the axis (27) of the pin (17), or in front of the plane.
