DETAILED DESCRIPTION OF THE INVENTION

(9) A footrest chassis 100 extending operation can be understood by looking at the figures sequentially from 1 to 6. A retraction operation takes place exactly the opposite manner, so that it can be followed by viewing the figures sequentially from 6 to 1.

(10) The footrest chassis 100 is attached to a seating furniture chassis 103 and comprises two parts that are interconnected only by the seating furniture chassis 103. The two parts are arranged parallel to each other and have the same structure, so that the retracting and extending process of both parts takes place in the same way. A footrest can be attached to both parts, thus interconnecting the two parts.

(11) The footrest chassis 100 comprises a first region 101 and a second region 102. A first part of a two-part footrest can be attached to the first region 101. A second part of the footrest can be attached to the second region 102. The footrest chassis 100 is thus designed for a two-part footrest.

(12) The first region 101 is fastened to the seating furniture chassis 103 by a first attachment element 104. The first attachment element 104 is embodied in the manner of a bolt and defines a first pivot axis about which both the first region 101 and the second region 102 are pivoted during the extending operation. Moreover, the first region 101 has a support surface 200 that is in contact with a bearing means 201 of the seating furniture chassis 103. A movement of the bearing means 201 triggers the pivoting movement of the first region 101 about the first pivot axis.

(13) The support surface 200 is pressed by a spring means against the bearing means 201 such that only a spring force acts on an object, an animal, or a person when the object, animal, or person is in the folding path of the footrest chassis 100.

(14) Moreover, the footrest chassis 100 has a second attachment element 105 that is attached to the seat furniture chassis 103. The second attachment element 105 is embodied in the manner of a lever.

(15) The second region is connected to the first region 101 by a first connecting means 106 and a second connecting means 107. The first connecting means 106 is embodied in the manner of a bolt and defines a second pivot axis about which the second region 102 is pivoted. The second connecting means 107 is embodied in the manner of a lever. Moreover, the footrest chassis 100 comprises a third connecting means 108 that is rotatably connected to the second attachment means 105 and to the second connecting means 107, respectively. The second connecting means 106 is also rotatably connected to the second region 102.

(16) When the footrest chassis 100 is extended, the bearing means 201 is pushed forward, so that the support surface 200 and the first region 101 are pivoted upward about the first pivot axis. This pivoting movement takes place counterclockwise and causes a relative movement between the second attachment element 105 and the third connecting element 108, resulting in a pivoting movement of the third connecting element 108. The pivoting direction of the third connecting element 108 is counter to the pivot direction of the first region.

(17) The pivoting movement of the third connecting means 108 causes a relative movement between the second connecting means 107 and the first connecting means 106, so that the second region 102 is pivoted about the second that is defined by the first connecting means 106. This pivoting movement takes place in the same pivot direction as the pivoting movement of the first region 101 about the first pivot axis.

(18) The second region 102 is thus moved by two superimposed pivoting movements about the first pivot axis and about the second pivot axis.

(19) In particular, two advantages are achieved by the mechanism described above. For one, the footrest chassis 100 requires relatively little space below the seating surface of the seating furniture for the pivoting operation. For another, the footrest chassis 100 can be used particularly well in seating furniture chassis 103 in which the footrest chassis is retracted or extended during the stowage and deployment process. This advantage becomes especially clear in looking at FIGS. 2 to 4. The second region 102 is deployed such that the feet of a user come into contact with the footrest before the footrest touches the user's legs from behind. This is especially convenient for users, as it prevents unpleasant pointwise contact of the calves with the footrest.
