See Figure 3.1.b) CHAIR TYPE II: FIXE
38、D SEAT ANGLE, TILTING BACKREST A chair that provides a fixedseat angle with a tilting backrest.

41、forward of the seat/backjunction on the longitudinal axis of the chaise lounge chair, or the point closest to this that allows the seatforce to be applied.3.6 CMD The BIFMA Chair Measuring Device used for the measurement of seating products.3.7 CYCLE A complete sequence of operation. This could incl
42、ude loading and unloading, stressreversal; opening and closing; or one complete revolution.3.8 FORCE A vector quantity, expressed in newton (N) or pounds force (lbf) that is an interaction withan object.3.9 FORM FITTING DEVICE A device that distributes a force over a 305 13 mm 89 13 mm (120.5 in 3.5

45、 element that supports loads during use. Foam andfabric, for example, are not generally considered load-bearing surfaces, nor are some portions of waterfalledges.3.13 LOSS OF SERVICEABILITY The failure of the product to support its intended load or to performall of its normal functions or adjustment
46、s.3.14 MULTIPLE SEATING Seating that has seating positions provided for more than one person.3.15 NORMAL USE CONDITION For consistency, the midpoint of any adjustment range, such as theheight adjustment or counter balancing force adjustment unless otherwise specified in the test method.3.16 PEDESTAL
47、 BASE A base that supports a chair by a single central structural member such as acolumn.3.17 ROCKING MOTION Move gently to and fro.3.18 SEAT OR SEATING POSITION The portion(s) of a unit intended for sitting, approximately 570 mm(22.5 in) in width. Attached table surfaces are not considered seating
48、positions. The number of seatingpositions shall be as specified by the manufacturer. If no manufacturers specification is available, or if thenumber of seating positions is not clearly defined by the design or contours of the seating surface (i.e.bench-type seating units), the number of seating posi
49、tions shall be determined as follows: divide the widthof the seating surface by 570 mm (22.5 in). To determine the number of seating positions round the resultdown to the nearest integer.3.19 SHEAR AND SQUEEZE POINT Shear and pinch points exist when the accessible parts are closeenough to each other to create a shear point or a pinch point. If two parts can move to create an openingthat vary its dimensions from more than 7
