Definitions

  • the invention relates to a seat element for row arrangement in the seating of halls, stadiums, stands and the like, the seat element consisting of a seat part, which can optionally be connected to a common row fastening, and a movably articulated, spring-loaded, backrest part which can be placed in the covering position on the seat part consists.
  • DE-OS 36 14 983 describes such seating elements in which the backrest part can be placed on the seat part in connection with a telescopic grandstand, which is horizontal has telescopically displaceable step elements with seat or tread surfaces.
  • the arrangement is such that when the telescopic grandstand is moved together, the erected backrest parts are forcibly placed on the seat parts, so that the moving together of the grandstand is not hindered.
  • these backrest parts must be opened by hand into the user position.
  • FR-A-1 036 815 describes a seat element in which the backrest part is pretensioned by a coil spring. If there are no counteracting erection forces, the spring force causes the backrest part to be automatically folded onto the seat. The spring force acts on the backrest part during the entire folding process.
  • the invention is based on the task, a seat element of the type described in such a way that the unused grandstand can be easily cleaned, and that when the user suddenly gets up in the event of panic there is no impairment of the escape routes by the towering backrest parts.
  • the seat element should have improved usage properties due to low erection forces for the backrest part when used as intended.
  • This object is achieved according to the invention in that the backrest part is pivotally attached to the seat part such that the backrest part falls back under the action of gravity in the cover position, and that at least one spring element is provided which the backrest part to initiate the pivoting movement over the Dead center position moved away. Even when the backrest part is raised from the cover position to the dead center position, only gravity acts on the backrest part.
  • spring elements other components which impart elastic prestress or weight loads can also be arranged on the backrest part.
  • An expedient design can provide that the backrest part is connected to the seat part with lateral tabs in pivot bearing arrangements and that a spring element is provided in the region of this pivot bearing arrangement.
  • the spring element can expediently be designed as a spring clip supported on a support surface of the lateral tabs.
  • a further advantage can optionally be achieved in that the backrest part is designed in such a way that when it rests on the seat part in the cover layer on its outer surface it forms a smooth surface of the folded seat element. This simplifies the cleaning of the rows of seats, and is expedient when the seating elements are arranged outdoors the backrest part overlapping the seat part, which optionally advantageously has a metal-coated outer surface or provided with a metal fitting, a protection of the seat part designed, for example, as a molded plastic part against the effects of weather, in particular UV radiation.
  • the support of the backrest part on the seat part can optionally also be advantageously designed in such a way that the seat and backrest surface in the cover layer is sealed by shaping or additional sealing elements.
  • the seat element can be designed with side surfaces smoothly adjoining similar seat elements in such a way that an essentially continuous row standing surface is created in the cover position and a continuous seat bench is created in the user position.
  • the seat part should generally be expedient to design the seat part to be connectable with a support element or a support surface that is continuous for several seat parts lying next to one another.
  • the arrangement can expediently be chosen so that the connecting elements of the seat part with a continuous support element, for example a hollow profile part, can be detached and tightened from the end face of the seat part.
  • the seat part and backrest part are advantageously one-piece plastic molded parts, but metal, for example aluminum or steel versions can also be expedient if appropriate depending on the purpose and location.
  • a favorable embodiment can provide that the length of the backrest part in connection with the length of the seat part is dimensioned such that the backrest part lies flush on the end face of the seat part in the covering position.
  • a compact arrangement that is protected against the weather is automatically created when the grandstand is not in use, which offers favorable cleaning options.
  • FIG. 1 shows a row arrangement of seat elements 1, 2 and 3, each consisting of a backrest part 4 and a seat part 5, the backrest part 4 as shown with the seat elements 2 and 3, is automatically placed on the seat part 5 without counteracting forces.
  • the seat part 5 is connected by screw connections 6, 7 via a holding bracket 8 to a support beam 9 arranged continuously in the row of seats.
  • a similar retaining bracket 8a is shown in front of the seat element 1, and an additional connection can be seen with a support bracket 10, which is fastened via a fastening plate 11 on the vertical side of a step 12, with rows of seats arranged in steps.
  • the backrest part 4 is fastened to the seat part 5 by means of tabs 13, 14 integrally formed on the side of the backrest part 4 in a pivot bearing 15 on both sides.
  • the details of the pivot bearing 15 can be seen more clearly in FIGS.
  • a bow spring 16 encompassing the pivot bearing 15, which has one end piece 17 on the seat part 5 and the other end piece 18 on a support piece 19 formed on the bracket part 13, which forms a contact surface 20, is supported.
  • a support pin 21 is provided on the seat part 5 in the case of the bow spring 16, which is approximately 1 cm wide in the normal seat size, for biasing under pretension.
  • the bow spring 16 only acts until the center of gravity of the backrest part 4 is above it Dead center position is led away. Then the backrest part 4 falls forward under the influence of its weight onto the seat part 5 and is placed in the cover position.
  • the backrest part 4 When the backrest part 4 is erected by the user, it must first overcome gravity without counteracting the spring to the dead center position before the spring preload takes effect. Thereafter, the backrest part 4 remains in the user position under low spring preload.
  • the spring action of the spring clip 16 leads the backrest part 4 back over the dead center position, so that the backrest part 4 is deposited under the action of gravity on the top of the seat part 5 and is supported by this.
  • the outer side 22 of the backrest part 4 can form a continuous standing surface when a number of seat elements 1, 2, 3 are lined up.
  • Seat part 5 and backrest part 4 are one-piece plastic molded parts, the outside 22 of the backrest part 4 optionally having a metallic coating or a metallic surface covering.
