DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[0031] An embodiment of the apparatus for mounting the child safety seat of the present invention will be described in detail by exemplifying a case in which the child safety seat is mounted on a rear seat for a vehicle for three users, with reference to the drawings. [0032] As shown in
[0037] Explaining about the apparatus for mounting the child safety seat, as shown in
[0041] As shown in
[0043] The pair of anchor members 32 are fixed on the lower bar 14 by welding, and the pair of anchor members 32 are disposed to be spaced apart from each other in the widthwise direction of the rear seat 10 for the vehicle, in accordance with the width of the corresponding seat portion, in such a way that the distance between the one anchor member 32 and the other anchor member 32 are set to be equal to that between the fixing hook FL and the fixing hook FR. Each pair of anchor members 32 are positioned between a rear end portion of the seat cushion 13 of the rear seat 10 for the vehicle and the lower end portion of the seat back 11 of the rear seat 10 for the vehicle, and each anchor member 32 is shaped into a substantially C-shape with being backwardly open in a case where it is seen from above. [0044] Each of the anchor members 32 includes a pair of leg portions 34 and a locking portion 36 which connects the pair of leg portions 34 and is detachably connected to the fixing hook F mounted on the child safety seat C. The locking portion 36 extends along the axial direction of the lower bar 14, and each of the pair of leg portions 34 extends in the direction crossing the axial direction of the lower bar 14. [0045] In the pair of anchor members 32, the locking portions 36 are adapted to be inserted into the groove ML of the fixing hook FL, the groove MR of the fixing hook FR, respectively, whereby the fixing hooks FL and FR are detachably fixed on the corresponding anchor members 32.
[0046] More specifically, the left leg portion 34B of the anchor member 32BB at the left side of the middle seat portion M is fixed on the lower bar 14 by welding so as to be partially wound around the lower bar 14 from above, while, the right leg portion 34A of the anchor member 32BB at the left side of the middle seat portion M is fixed on the lower bar 14 by welding so as to be partially wound around the lower bar 14 from below, and the left leg portion 34B of the anchor member 32CA at the middle side of the left seat portion L is fixed on the lower bar 14 by welding so as to be partially wound around the lower bar 14 from above, while, the right leg portion 34A of the anchor member 32 CA at the middle side of the left seat portion L is fixed on the lower bar 14 by welding so as to be partially wound around the lower bar 14 from below. Since the two adjacent leg portions 34, one of which belongs to the pair of anchor members 32 in the seat and the other of which belongs to another pair of anchor members 32 adjacent to the former pair of anchor members 32 in another seat adjacent to the former seat, are fixed on the lower bar 14 in such a way that one of the leg two adjacent portions 34 is fixed at its one vertical side and the other of the two adjacent leg portions 34 is fixed at its vertically opposite side, the anchor member 32BB at the left side of the middle seat portion M and the anchor member 32CA at the middle side of the left seat portion L can be disposed more closely adjacent to each other in the widthwise direction of the vehicle. [0047] In particular, in two anchor members 32 close to each other in the widthwise direction of the vehicle (the anchor member 32BB at the left side of the middle seat portion M and the anchor member 32CA at the middle side of the left seat portion L), they can be arranged closer to each other in the widthwise direction of the vehicle by the leg portion 34 at the side of the other of the two anchor members 32 in the one of the two anchor members 32 and the leg portion 34 at the side of the one of the two anchor members 32 in the other of the two anchor members 32 being disposed to be overlapped to each other.
[0048] Alternatively, in a case where the bracket 16B for the bracket for the seat frame is omitted, the right leg portion 34A of the anchor member 32BA at the right side of the middle seat portion M may be fixed on the lower bar 14 by welding so as to be partially wound around the lower bar 14 from above, while, the left leg portion 34B of the anchor member 32BA at the right side of the middle seat portion M may be fixed on the lower bar 14 by welding so as to be partially wound around the lower bar 14 from below, and the right leg portion 34A of the anchor member 32AB at the middle side of the right seat portion R may be fixed on the lower bar 14 by welding so as to be partially wound around the lower bar 14 from above, while, the left leg portion 34B of the anchor member 32 AB at the middle side of the right seat portion R may be fixed on the lower bar 14 by welding so as to be partially wound around the lower bar 14 from below, whereby the anchor member 32BA at the right side of the middle seat portion M and the left anchor member 32AB at the middle side of the right seat portion R may be arranged close to each other in the widthwise direction of the vehicle. [0049] In this connection, in the pair of anchor members 32, the right leg portion 34A and the left leg portion 34B may be fixed on the lower bar 14 by welding so as to be partially wound around the lower bar 14, not only from above or below, respectively, but also from below or above, respectively.
[0050] More specifically, in the pair of anchor members 32, a tip end portion of the leg portion 34A is fixed on the lower bar 14 so as to be wound around the lower bar 14 over a peripheral angel range between 90 and 180, from above or below, while, a tip end portion of the leg portion 34B is fixed on the lower bar 14 so as to be wound around the lower bar 14 over a peripheral angel range between 90 and 180, from below or above. [0051] As shown in
[0052] Each of the pair of leg portions 34A,B includes an arcuate portion 40 extending in the direction crossing the axial direction of the lower bar 14 along a surface 38 of the lower bar 14, and the pair of anchor members 32 are welded on the surface 38 of the lower bar 14 by arc welding via the arcuate portion 40. [0053] Alternatively, as shown in
[0055] Still alternatively, the bracket 16B for the seat frame is provided so as to fix and support the intermediate lower portion 26 in the widthwise direction of the rectangular seat back frame 12 on the floor panel 18, and the lower bar 14 includes a first portion which extends between the one of the lower end corner portion 20 and the intermediate lower portion 26, of the rectangular seat back frame 12 and a second portion which extends between the other of the lower end corner portion 20 and the intermediate lower portion 26, of the rectangular seat back frame 12, whereby each of the first and second portions may be individually fixed on the surface corresponding to the opposed surface of the bracket 16B for the seat frame. For instance, the first portion may correspond to the right or left seat portion R, L, and the second portion may correspond to the middle seat portion M and the left or right seat portion.
[0056] Now, a technical effect of the apparatus for mounting the child safety seat C on with the above structure is explained about, including a method of mounting the child safety seat C on the seat for the vehicle. [0057] In the seat 10 for the vehicle with a plurality of seat portions adjacent to each other on which the lower bar 14 extending in the widthwise direction of the vehicle over the entirety of its width is provided, the method of mounting the child safety seat C on the seat for the vehicle includes a step of selecting a plurality of seat portions on which the child safety seats C are mounted, and a step of fixing pair of anchor members 32 on the lower bar 14 by welding, in accordance with each of the selected plurality of seat portions adjacent to each other. [0058] For instance, the positioning of fixing the pair of anchor members 32 on the lower bar 14 by welding is determined by selecting the middle seat portion M and the left seat portion L adjacent to each other on each of which the child safety seat C is to be mounted.
[0059] Since each pair of anchor members 32 are disposed to be spaced apart from each other in the widthwise direction of the rear seat 10 for the vehicle, in accordance with the width of the corresponding seat portion, and includes the pair of leg portions 34A,B 34, and the locking portion 36 which connects the pair of leg portions 34A,B and is detachably connected to the child safety seat C, the positioning of the pair of anchor members 32 on the lower bar 14 may be carried out by passing the lower bar 14 from its one end between the pair of leg portions 34A,B of each anchor member 32 in the axial direction of the lower bar 14 to position the pair of anchor members 32 on a longitudinal position of the lower bar 14, and rotate the anchor members 32 about the axial direction of the lower bar 14.
[0060] Then, in two pairs of anchor members 32 adjacent to each other, the leg portion 34 at the side of the other pair of anchor members between the leg portions 34A,B of the one of the pair of anchor members 32 at the side of the other pair of anchor members 32 is fixed on the lower bar 14 so as to be partially wound around the lower bar 14 from above or below, while, the leg portion 34 of the other of the pair of anchor members 32 at the side of the one pair of anchor members 32 is fixed on the lower bar 14 so as to be partially wound around the lower bar 14 from below or above, whereby the two pairs of anchor members 34 adjacent to each other are disposed more closely adjacent to each other in the widthwise direction of the seat for the vehicle. [0061] The mounting of the apparatus for mounting the child safety seat C on the seat for the vehicle is completed by fixing the lower bar 14 on which the anchor members 32 are welded on the rear seat 10 for the vehicle via the brackets 16 for the seat frame.
[0062] According to the apparatus for mounting the child safety seat C, in the seat 10 for the vehicle with a plurality of seat portions adjacent to each other, since the lower bar 14 is provided which is fixed on the seat 10 for the vehicle and extends in the widthwise direction of the seat 10 for the vehicle over the entirety of its width, a plurality of pairs of anchor members 34 are fixed on the lower bar 14, the two anchor members 34 in each pair of anchor members 34 are disposed to be spaced apart from each other in the widthwise direction of the seat 10 for the vehicle, in accordance with the width of the corresponding seat portion on which the child safety seat C is to be mounted, and are fixed on the lower bar 14 by welding, the child safety seat C can be detachably fixed on the seat portion via the corresponding pair of anchor members 32.
[0063] More specifically, in a case where the child safety seat C is fixed on the seat cushion 13 for the vehicle, firstly, the child safety seat C is moved rearwardly along a surface of the seat cushion 13 for the vehicle, whereby the locking portions 36 of the pair of anchor members 34 are inserted into the groove ML of the fixing hook FL and the groove MR of the fixing hook FR, respectively, and thus, the child safety seat C is fixed on the seat cushion 13 for the vehicle by means of a seat belt, or a dedicated belt (not shown).
[0064] According to the apparatus for mounting the child safety seat C, even if the child safety seat Cs are simultaneously mounted on the plurality of seat portions adjacent to each other, in two pairs of anchor members 32 adjacent to each other among said plurality of pairs of anchor members 32, since, with respect to the one pair of anchor members 32, the one of said leg portions 34 at the side of the other pair of anchor members 32 is fixed on said lower bar 14 so as to be partially wound around said lower bar 14 from above or below, while, the other of said leg portions 34 at the opposite side is fixed on said lower bar 14 so as to be partially wound around said lower bar 14 from below or above, while, with respect to the other pair of anchor members 32, the one of said leg portions 34 at the side of the one pair of anchor members 32 is fixed on said lower bar 14 so as to be partially wound around said lower bar 14 from above or below, while, the other of said leg portions 34 at the opposite side is fixed on said lower bar 14 so as to be partially wound around said lower bar 14 from below or above, the adjacent leg portions 34, one of which belongs to the one pair of anchor members 32 in the one seat portion, the other of which belongs to the other adjacent pair of anchor members 32 in the other adjacent seat portion, are fixed on the lower bar 14 by welding at vertically opposite positions of the lower bar 14, and as a result, said two pairs of anchor members 32 adjacent to each other among the plurality of pairs of anchor members 32 can be disposed more closely adjacent to each other in the widthwise direction of the seat for the vehicle, whereby a restriction on a position of the child safety seat C on the seat 10 for the vehicle due to a limited width of the vehicle on which the seat 10 for the vehicle is provided can be eased, while at the same time, the child safety seat C can be mounted on the seat 10 for the vehicle in a precise and reliable manner in such a way that the child safety seat C can endure an impact load in the longitudinal direction of the vehicle without the lower bar 14 being deflected, even if the two pairs of anchor members 32 adjacent to each other in the widthwise direction of the seat 10 for the vehicle are mounted on the lower bar 14.
[0065] Alternatively, since the pair of anchor members do not have to be provided on each of the plurality of seat portions adjacent to each other, as shown in
[0066] As described above, the preferred embodiment of the present invention was described in detail, however, it is evident that those skilled in the art could modify or change the embodiment in various manners without departing from the scope of the present invention. [0067] For instance, in this embodiment, the rectangular seat back frame 12 for the left seat portion and the rectangular seat back frame 12 for the middle and right seat portions are connected to each other in a plane form, however, an auxiliary bar may be provided so as to vertically extend at the border line portion between the left and the middle seat portions, in the rectangular seat back frame 12. [0068] For instance, in this embodiment, the child safety seat C is mounted on the rear seat for three users, however, the child safety seats C may be simultaneously mounted on the seat portions adjacent to each other, or the child safety seat C may be mounted on either of the seat portions adjacent to each other, so long as the child safety seat C is mounted on the seat for the vehicle with a plurality of seat portions adjacent to each other.
[0069] For instance, in this embodiment, the lower bar 14 is fixed on the seat for the vehicle via a supporting bracket, however, the lower bar 14 may be directly fixed on the seat for the vehicle without using the supporting bracket, so long as the child safety seat C is reliably kept fixed on the seat even when an impact load in the longitudinal direction of the vehicle is exerted on the child safety seat C. [0070] For instance, in this embodiment, the pair of anchor members are made of a hollow pipe with a circular cross section, however, a sloid member with a rectangular cross section may be adopted. [0071] For instance, in this embodiment, the fixing hook is detachably fixed on the locking portion via the groove, however, the fixing hook may be detachably fixed on the corresponding locking portion by another locking configuration.
