Description

  The present invention relates to a vehicle seat having an ISO-FIX compatible anchor that can hold an ISO-FIX type child seat.

  There is an international standard ISO-FIX as a method for fixing a child seat to a vehicle seat, and a vehicle seat having an ISO-FIX compatible anchor that can fix the ISO-FIX type child seat is disclosed in, for example, Japanese Patent Application Laid-Open No. 2008-105580. It is disclosed in publications and the like.

  In this type of ISO-FIX child seat, left and right locking members are provided at the rear thereof, and an anchor that receives the locking member (an ISO-FIX compatible anchor) is used for a rear end of a cushion of a vehicle seat or a seat back. Arranged at the lower end.

  An anchor is known that is formed by bending a wire material (solid bar) into a substantially U-shape in plan view in which the front ends of the left and right sidebars that extend parallel to each other in front are connected by a front bar. ing. The child seat has left and right engaging members extending rearward, for example, in the lower part of the back, and the engaging members are formed in a substantially bifurcated shape in side view with a long groove-like notch (engagement port) at the tip. The child seat is held by the anchor by engaging the joint with the front bar of the anchor. Usually, the lower arm of the bifurcated engagement member is formed shorter than the upper arm so that the engagement member smoothly engages with the front bar.

  Usually, the anchor is provided at the rear end of the seat cushion or the lower end of the seat back. Both the seat cushion and seat back are covered with a pad (seat pad) made of foamed material such as foamed urethane, and the pad is covered with a trim cover. Is formed on the pad. The case where the anchor is provided at the rear end of the seat cushion will be described. The seat cushion frame is formed in a substantially rectangular shape in a plan view in which the front and rear ends of the left and right side frames are connected by, for example, a connecting pipe. It is fixed to the connecting pipe at the back of the seat and is arranged in the pad recess at the rear end of the seat cushion.

Since the appearance design is impaired when the pad recess and the anchor disposed therein are visible, a configuration has been proposed in which a box-shaped bezel with an open upper end is placed on the pad recess to hide the pad recess.
If a cap that covers the opening of the bezel is attached when the child seat is not attached, the anchor in the pad recess is not visible, and the appearance design is not impaired. However, when the cap is provided so as to be separable from the bezel, it is easily lost when the cap is separated. Therefore, a configuration in which the cap is swingably attached to the bezel is well known.

For example, Japanese Patent Application Laid-Open No. 2008-105580 describes a configuration in which a bezel is covered with a pad recess and an opening of the bezel is covered with a swingable cap. The anchor extends from the hole (bottom hole) formed in the bottom wall (back surface) of the bezel to the pad recess.
In this configuration, the pad recess is concealed by the bezel, and when the child seat is not attached, the cap covers the pad recess and conceals the anchor in the pad recess. When the child seat is mounted, the child seat is mounted on the vehicle seat by swinging the cap of the bezel to expose the anchor and engaging the child seat engaging member with the front bar of the anchor in the pad recess.

  German Utility Model DE200006692U1 describes a cap that can be stored in a bezel. That is, the cap has a substantially T-shape in a side view with a pair of left and right side walls extending rearward in the center of the back surface, and two pairs of hinge pins that are slightly separated in the front-rear direction from the pair of left and right side walls respectively protrude outward. Yes. A pair of left and right guide grooves extending in the front-rear direction are formed on the left and right inner surfaces of the bezel, and the hinge pin of the cap is slidably fitted into the guide groove, and the front hinge pin is guided by the biasing force of the leaf spring provided in the bezel. By pressing the front end of the cap, the cap is held at a position covering the opening of the bezel. Here, since the two hinge pins are fitted in the guide groove apart from each other in the front-rear direction, the cap is held under the biasing force of the leaf spring at a position covering the opening of the bezel without swinging.

  When the child seat engaging member is pushed into the pad recess when the child seat is mounted, the engaging member presses the cap against the biasing force of the leaf spring, and the two hinge pins of the cap slide along the guide groove of the bezel. . Since the guide groove has an arc shape that rises toward the rear (bezel bottom direction), when the hinge pin is slid along the guide groove by being pushed by the engaging member, the cap has the hinge pin as the swing center. Swinged up and moved up, moved from the tip of the engagement member to the upper surface, pressed against the upper surface of the engagement member by the biasing force of the leaf spring, and the rear hinge pin was in contact with the rear end of the guide groove Stored in the bezel.

JP 2008-105580 A German utility model DE200006692U1

  Japanese Patent Application Laid-Open No. 2008-105580 requires a means for fixing the cap in a state where the cap is swung and the bezel opening is opened when the child seat is mounted. Further, a space for securing a swing locus for swinging the cap is required around the opening of the bezel, and the shape and arrangement of the peripheral parts of the bezel opening are restricted in design.

According to German utility model DE200006692U1, if the child seat engaging member is pushed into the pad recess, the cap is flipped up and stored in the bezel in a state of being pressed against the upper surface of the engaging member. Absent. In addition, since the cap swings in the bezel, there is no need to provide a space around the opening of the bezel to secure the swing trajectory of the cap, and the shape and arrangement of the peripheral parts of the bezel opening are not restricted in design. .
Further, when the child seat is attached, the cap is stored in the bezel, so that the appearance is good.

  However, the front face of the cap (front face) is pressed against the biasing force of the leaf spring by the tip of the child seat engaging member pushed into the bezel when the child seat is attached, and the front face of the cap is under the biasing force of the leaf spring. It is pressed against the upper surface of the engaging member, and is flipped up and stored while sliding on the upper surface of the engaging member. When the engagement member is pulled out from the pad recess by releasing the engagement with the anchor, the front surface of the cap is pressed against the upper surface of the engagement member under the biasing force of the leaf spring as the engagement member is pulled out. Is moved to the tip of the engaging member, and returned to and held at a position covering the opening of the bezel while being pressed against the tip of the engaging member under the biasing force of the leaf spring.

  In this way, the distal end of the child seat engaging member pushed into the pad recess is pressed against the front face of the cap against the biasing force of the leaf spring, and is flipped up while sliding on the upper surface. Since it repeats, there exists a possibility that the front surface may be damaged by contact with an engaging member, and the external appearance design of a cap front surface may be impaired. Further, if an ISO-FIX anchor mark (pictogram) or the like is drawn on the front surface of the cap, the surface of the cap may be abruptly damaged, and it is difficult to attach the mark (pictogram) to the front surface of the cap.

One end of the leaf spring is fixed to the bezel in a curved form, and the other end (free end) is sandwiched between two pins on the back of the cap. When the child seat is not attached, the leaf spring is positioned so as to cover the opening of the bezel. The cap is held slightly tilted backward.
However, since a leaf spring is required and the number of parts increases, one end of the bezel is fixed and the cap is held by a curved cantilever-like elastically deformable leaf spring. It is difficult to position the other end (free end) so that the cap is positioned at a predetermined position covering the opening, and the configuration is inevitably complicated.
In the configuration in which the front surface of the engagement member is pressed against the upper surface of the engagement member under the biasing force of the leaf spring and the cap is stored in the bezel, no abnormal noise due to play is generated even when the vehicle is traveling.

  An object of the present invention is to provide a vehicle seat in which a cap is stored in a bezel without damaging the front surface (front surface) of the cap or generating noise due to play with a simple configuration.

Therefore, in the present invention, the cap is held at a position covering the opening of the bezel without applying a biasing force, and when the cap is pushed in, the cap is regulated by the regulating pin provided on the bezel and is swung up and flipped up. The hinge pin is pushed into the guide groove of the bezel and slides, and the protrusion on the front surface of the cap is brought into contact with the bezel ceiling surface so that the cap is stored immediately below the bezel ceiling surface, and the cap is held in its retracted position by a stopper.
That is, according to the first aspect of the present invention, the recess for storing the anchor used for holding the child seat is formed in the pad covered with the trim cover, and the bezel having the opening is put on the pad recess, and the cap is In the vehicle seat in which the opening of the bezel is covered, the cap has a protrusion on the front surface thereof, and the cap is held at a position covering the opening of the bezel by the engaging means provided between the bezel and the cap. The back of the cap extends linearly in the front-rear direction, the guide groove is provided on the left and right side surfaces of the bezel, the hinge pin is provided on the cap and slidably fitted into the guide groove, and the regulation pin covers the opening of the bezel The hinge pin protrudes inward from the left and right side surfaces of the bezel so as to be able to regulate the swing of the cap inward of the bezel by contacting the hinge pin and the guide When a pushing force is applied to the cap that covers the bezel opening, the back surface of the cap is slidably contacted with the restriction pin, the cap swings and swings up around the hinge pin, and the hinge pin moves through the guide groove. The cap is pushed and slides so that the protrusion on the front of the cap abuts against the ceiling surface of the bezel and the cap is stored directly under the ceiling surface of the bezel, allowing the cap to move to the bezel under the pressing force applied to the cap. A stopper is provided that restricts the movement of the cap when it is stored and the pressing force is removed, and holds the cap in its retracted position.

In the present invention according to claim 1, an independent member such as a leaf spring is not required, the number of parts does not increase, the cap can be held at a position covering the opening of the bezel by the holding means, a regulation pin, a protrusion, Since any member for holding such as the holding means can be formed at the time of forming the bezel and the cap, the configuration is simplified.
Further, the cap is stored regardless of the pushing-in of the child seat engaging member, and the front surface of the cap is not damaged by the child seat engaging member. Further, in the retracted position, the protrusion on the front surface of the cap contacts the bezel ceiling surface, and the front surface of the cap itself is not pressed against the bezel ceiling surface, and the front surface of the cap is not damaged.
Then, the cap is held at a position covering the opening of the bezel by the holding means, and in the retracted position, the cap is held by the bezel ceiling surface and the regulating pin while the projection on the front surface is in contact with the bezel ceiling surface and is moved by the stopper. Be regulated. For this reason, no matter what the noise is due to backlash when the vehicle is running, regardless of whether the cap covers the bezel opening or the storage position.

FIG.

  The cap has a protrusion on the front surface thereof, and the cap is held at a position covering the opening of the bezel by an engaging holding means provided between the bezel and the cap. Extending linearly in the front-rear direction, guide grooves are provided on the left and right side surfaces of the bezel, and hinge pins are provided on the cap and slidably fitted into the guide grooves. A restricting pin protrudes inward from the left and right side surfaces of the bezel so as to abut against the back surface of the cap covering the opening of the bezel so as to restrict the swing of the cap inward of the bezel. When a pressing force that pushes the hinge pin into the guide groove and slides is applied to the cap that covers the opening of the bezel, the back surface of the cap is slidably contacted with the restriction pin, and the cap swings and swings up with the hinge pin as the swing center. The guide groove is pushed and slides, and the protrusion on the front surface of the cap is brought into contact with the bezel ceiling surface, so that the cap is stored immediately below the bezel ceiling surface. A stopper that allows the cap to move to the bezel under the pressing force applied to the cap and restricts the movement of the cap when the cap is retracted and the pressing force is removed, and holds the cap in the retracted position. Sheets are provided.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic side view of a vehicle seat according to an embodiment of the present invention, and FIG. 2 is a perspective view of a bezel and a cap of the vehicle seat. The front, rear, left, and right refer to the directions viewed from the driver seated on the driver seat, and are indicated by Fr, Rr, L, and R.

  As shown in FIG. 1, the vehicle seat 10 includes a seat back 12 and a seat cushion 14, and a seat belt (not shown) is attached to the seat. The seat cushion 14 is configured by covering a cushion frame (not shown) with a pad (seat pad) 14-1 made of a foamed material such as foamed urethane, and covering the pad with a trim cover 14-2. It becomes the composition of.

  A pad recess 14-1a is formed by notching the pad 14-1 at the rear end of the seat cushion 14, and a trim cover (not shown) covering the pad is opened above the pad recess. In addition, although the pad recessed part 14-1a is formed in the seat cushion rear end in FIG. 1, it is not limited to this structure, You may provide a pad recessed part in a seat back lower end.

For example, at the rear end of the seat cushion 14, left and right anchors 30 corresponding to the left and right ISO-FIX for holding the ISO-FIX type child seat 20 on the seat cushion are predetermined in the left-right direction of the vehicle seat 10. They are arranged at intervals.
The child seat 20 has, for example, left and right engaging members 24 extending rearward from the lower portion of the rear surface 22 thereof, and the engaging member has an engaging port 24a formed of a long groove-like notch at the tip. The anchor 30 is formed by bending a wire material into a substantially U-shape in plan view in which front ends of left and right side bars 30a extending in parallel to each other are connected by a front bar 30b. It is fixed to a connecting pipe (not shown) installed in the left-right direction between the rear ends (not shown) and extends forward.

  Normally, the child seat 20 is such that the left and right engaging members 24 are brought close to the corresponding anchors 30 from the front in a state where the rear side sinks and is inclined, and the engaging holes (notches) 24a of the engaging members are engaged with the front bar 30b. Thus, the child seat 20 is held by the anchor and disposed on the seat cushion 14. The anchor front bar 30b is engaged until it reaches the end of the engagement port 24a of the engagement member, whereby the child seat 20 is completely held by the anchor 30.

The pad recess 14-1a is covered with a box-shaped bezel 40 having a substantially rectangular cross section with an open front, and a cap 50 is attached to the bezel opening (front opening) 40F so as to cover the opening. For example, the bezel 40 and the cap 50 are formed from a thermoplastic resin or the like.
In the embodiment, the bezel 40 is integrally formed with the flange 41 around the opening 40F, but is not limited thereto. However, if the bezel 40 is provided with a flange, the bezel can be easily attached to the trim cover by sewing the trim cover terminal around the pad recess 14-1a on the lower surface of the flange.

The bezel 40 has a shape in which the rear surface (rear surface) is also opened. When the bezel is put on the pad recess 14-1 a, the anchor is extended and positioned in the bezel, and when the bezel opening 40 F is covered by the cap 50, the anchor 50 is anchored. 30 is hidden and the position of the anchor is difficult to understand. Therefore, an ISO-FIX anchor mark (pictogram) M may be drawn on the front face (front face) of the cap to clearly indicate the position of the anchor (see FIG. 2).
The bezel 40 may be a bottom, an insertion hole through which the anchor 30 is inserted may be provided on the bottom wall (back surface), and the anchor may protrude from the insertion hole into the bezel.

FIG. 3 is a right side view of the bezel and cap of the vehicle seat.
For example, the front surface of the bezel 40 is formed in a slope shape with the lower front surface positioned in front of the upper side, and the cap 50 is formed in a substantially U shape in plan view with left and right sleeves (side portions) 50S. .
A pair of left and right guide grooves 42 linearly extending in the front-rear direction are provided at the upper part of the left and right side surfaces 40S of the bezel, and a pair of left and right guides that are fitted in the guide grooves and are slidable along the guide grooves. The hinge pin 52 protrudes outward from the upper portion of the sleeve 50S, and the cap is attached (incorporated) to the bezel by fitting the hinge pin into the guide groove. A protrusion 56 protrudes from the front surface of the cap. In the embodiment, a pair of left and right partial spherical protrusions are formed at the lower portion of the front surface of the cap.

The guide groove 42 has a through groove shape extending substantially horizontally in the front-rear direction, and the length of the cap in the front-rear direction so as to secure a space for storing the cap 50 between the bezel ceiling surface (upper surface) 40Up. It is formed away from the bezel ceiling surface by a distance corresponding to (thickness).
A stopper that allows the cap to move to the bezel 40 under the pressing force applied to the cap 50, and restricts the movement of the cap when the cap is stored and the pressing force is removed, and holds the cap in its storage position. 42 'is provided.

A pair of left and right restricting pins 44 project inward from the left and right side surfaces 40S of the bezel at the front and below the front end 42Fr of the guide groove, and the restricting pins contact the back surface of the cap, for example, the back surface 50Sa of the cap sleeve. By contact, the swinging of the cap is restricted.
For example, the regulation pin 44 and the hinge pin 52 are both cylindrical.

  It is sufficient that the regulation pin 44 abuts on the back surface of the cap 50 to regulate its swinging, and the position where the regulation pin abuts on the back surface of the cap is not limited to the back surface of the sleeve. However, in the configuration in which the cap 50 is formed in a substantially U shape in plan view with the left and right sleeves 50S and the restriction pins are in contact with the back of the cap on the back of the left and right sleeves, the left and right can be contacted uniformly. Therefore, the hinge pin 52 can slide smoothly along the guide groove. Further, the protruding length of the regulation pin 44 can be shortened, and the configuration is not complicated.

  For example, the stopper 42 ′ is configured by a protrusion provided on the lower surface of the guide groove at the rear portion of the guide groove 42 and pressing the hinge pin 52 against the rear end 42 Rr of the guide groove to restrict the movement of the cap. The protrusion (stopper) 42 'of the guide groove allows the hinge pin 52 to pass over and pass under the pressing force applied to the cap 50. When the pressing force is removed, the regulating pin is pressed against the rear end 42Rr of the guide groove. It is sufficient if it has a function of preventing the cap from moving in the direction in which it is engaged and returning (forward; the direction of opening of the bezel) and holding the cap in its retracted position. For example, the stopper 42 ′ is constituted by a protrusion such as a partial cylinder or a partial sphere having a cross section of a mountain shape (including a curved shape and a partial circular shape). The guide groove protrusions (stoppers) 42 ′ may be provided on the corresponding upper surface instead of the lower surface of the guide groove 42.

4 (A), (B), and (C) are sectional views of the cap, the bezel at the initial position of the cap (position covering the opening of the bezel), the intermediate position, and the retracted position, along the line XX in FIG. 5 is a cross-sectional view of the bezel and cap taken along line YY in FIG. 4A, and FIG. 6 is an enlarged view of the upper half of the bezel and the cap at the retracted position in FIG. 4C.
Between the bezel 40 and the cap 50, there is provided holding means 60 for holding the cap on the bezel at a position covering the opening of the bezel. The holding means 60 includes a pair of left and right engagement protrusions 54 protruding outward at the lower portions of the left and right sleeves 50S of the cap, and a pair of corresponding left and right engagements formed on the left and right side surfaces 40S of the bezel below the restriction pin 44. A combination with the hole 46 is used. For example, as shown in FIG. 5, the engagement protrusion 54 is a partially spherical engagement protrusion, the engagement hole 46 is a hole (through hole) that penetrates the side surface of the bezel, and the engagement protrusion fits into the engagement hole. The cap is held on the bezel by being engaged (engaged). Instead of the through hole, a partial spherical engagement hole corresponding to the partial spherical engagement protrusion 54 may be used as the engagement hole.

  The holding means 60 is not limited to a combination of the engaging protrusion 54 and the engaging hole 46 as long as the cap 50 is held at a position covering the opening 40F of the bezel. However, if the holding means is composed of the combination of the engaging protrusion 54 and the engaging hole 46, the holding means is simplified, and the opening 40F of the bezel is covered by the engagement of the engaging protrusion and the engaging hole. The cap can be quickly and easily held in the position (initial position).

  For example, as shown in FIG. 3, when the cap 50 is aligned with the opening 40F of the bezel and pushed in the direction of the arrow (rearward) to engage the engagement protrusion 54 with the engagement hole 46 on the side surface of the bezel, Is held at a position covering the front opening 40F of the bezel, and the anchor 30 in the bezel is hidden by the cap.

When the cap 50 is pushed into the bezel 40, the engaging protrusion 54 is engaged with the engaging hole 46 on the side surface of the bezel, and the hinge pin 52 is fitted into the guide groove 42. At this position, the cap 50 covers the opening 40F. It is attached to the bezel 40 (initial position; FIG. 4 (A)). The engaging projection 54 located on the lower half of the cap is not only engaged with the engaging hole 46 on the side of the bezel, but the hinge pin 52 located on the upper half is fitted in the guide groove 42 on the side of the bezel. The cap 50 is securely held at its initial position covering the opening 40F because it is attached to the bezel at two locations, upper and lower.
The cap 50 is held at the initial position (position covering the opening 40F of the bezel) by the holding means 60 (engagement projection 54, engagement hole 46) without requiring an independent member such as a leaf spring. The number of members does not increase. Further, the holding means 60 (engagement protrusion 54, engagement hole 46) and the stopper 42 'formed of the protrusion can be formed at the time of forming the bezel 40 and the cap 50, and the configuration is simplified.

In the initial position of the cap (FIG. 4A) in which the cap 50 is attached to the bezel 40 so as to cover the opening 40F (FIG. 4A), the cap hinge pin 52 is fitted into the guide groove 42 of the bezel and the cap engaging projection 54 is The cap is engaged with the engagement hole 46 of the bezel, but the cap back surface 50Sa abuts on the restriction pin 44 of the bezel and the positional relationship such that the hinge pin is pressed against the front end 42Fr of the guide groove has a hinge pin, a guide groove, a restriction pin, An engagement protrusion and an engagement groove are set.
In this way, the engagement protrusion 54 is engaged with the engagement hole 46 on the side surface of the bezel, and the cap 50 is not only held in its initial position covering the opening 40F by the holding means 60, but the cap 50 moves backward. (Swing) is regulated by the regulation pin 44, and the forward movement (swing) of the cap is regulated by pressing the hinge pin 52 against the front end 42Fr of the guide groove, so that the cap is held without backlash. Occurrence of abnormal noise caused by looseness when the vehicle is traveling at the initial position is prevented.

  Even when a pressing force for pushing the cap 50 into the bezel 40 is applied to the lower half portion thereof, the regulation pin 44 positioned below the hinge pin 52 abuts against the cap back surface 50Sa, and the cap swings around the hinge pin as a swing center. To prevent, the cap is held in its initial position without being pushed into the bezel.

  In the present invention, the cap 50 cannot be stored simply by being pushed in, and an operation of pulling the cap and swinging it upward is required before pushing. That is, as indicated by an arrow in FIG. 4A, the cap 50 is pulled out and swinged upward, and the cap is pushed into the bezel 40 while being flipped up (FIG. 4B). Is removed from the position that covers (initial position). Then, the child seat engaging member 24 is engaged with the anchor 30 in the bezel, and the child seat 20 is mounted on the seat 10.

  The storage of the cap 50 will be described in detail. As shown in FIG. 4 (A), since the cap covers the opening of the bezel 40F leaving a space below, the finger inserted from the space below the cap is placed at the lower end of the cap. If it is pulled forward as shown by an arrow, the engagement protrusion 54 of the cap is detached from the engagement hole 46 of the bezel and the engagement is released. Then, if the cap 50 is lifted as it is and the cap is pushed into the bezel 40 from its upper end while the back surface 50Sa is in sliding contact with the regulating pin 44, the hinge pin 52 slides along the guide groove 42, and FIG. As shown in FIG. 4, the cap rides on the restriction pin, swings around and is flipped up.

  Even if a space is left below the cap 50, the anchor 30 is located in the back of the bezel 40, so that the anchor is not visible and the appearance design is not impaired. Of course, the cap 40 may be formed in a shape that covers the entire surface of the opening 40F of the bezel. In this case, for example, a locking groove for locking a finger may be provided in the lower portion of the front surface of the cap.

The cap back surface 50Sa that abuts against the regulation pin 44 has an upper end (1/3 to 1/4 of the total length) on the back surface so that the cap rides on the regulation pin and swings smoothly around it. After that, it becomes a guide surface (cam surface) having a sloped shape that is parallel to the front surface and that moves away from the front surface of the cap as it goes downward.
When the cap 50 is flipped up until the rear end of the cap back surface 50Sa rides on the restriction pin 44, the hinge pin 52 that has slid along the guide groove 42 has a protrusion (stopper) 42 in the guide groove that protrudes from the rear bottom of the guide groove 42. Passing over (passes) (slides), abuts against the rear end 42Rr of the guide groove and is prevented from sliding. If the pushing force for pushing the cap 50 into the bezel 40 is removed, the movement of the hinge pin in the returning direction (forward; the opening direction of the bezel) is hindered (restricted) by the stopper 42 '.
That is, the hinge pin 52 is held by being prevented from sliding forward by the guide groove protrusion (stopper) 42 'and backward sliding by the rear end 42Rr of the guide groove. Then, the protrusion 56 on the front surface of the cap and the bezel ceiling surface 40Up come into contact with each other, and the front surface of the cap 50 is stored and held in its storage position slightly separated from the bezel ceiling surface (FIGS. 4C and 6). .
In addition, since the cap back surface 50Sa is an inclined guide surface (cam surface) that moves away from the front surface of the cap as it goes downward, the cap 50 is pushed up by the restriction pin when the cap back surface 50Sa rides on the restriction pin 44, In the retracted position, the protrusion 56 on the front surface of the cap is pressed against and abuts the bezel ceiling surface 40Up, and is sandwiched and stored by the regulation pin and the bezel ceiling surface from above and below.

  As described above, when the cap 50 is pushed in, the cap is regulated by the bezel regulating pin 44, and the cap is swung up and stored regardless of the pushing of the engaging member 24 and stored in the bezel. Further, even when the engaging member 24 is pushed into the bezel 40 in order to engage with the anchor 30 in the bezel (specifically, the front bar 30b) when the child seat is mounted, the cap 50 is stored in the bezel and engaged. The engagement member does not press the front surface of the cap and does not contact the front surface of the cap.

Since the engagement member does not press the front surface of the cap when the engagement member 24 is pushed in, the front surface of the cap is not damaged by the engagement member, and the appearance design of the cap is not impaired. The cap 50 is stored with the front face 56 and the bezel ceiling surface 40Up in contact with each other, and the front surface of the cap 50 and the bezel ceiling surface are not in direct contact with each other. The front of the cap will not be damaged.
In this manner, the engaging member 24 does not press the front surface of the cap 50, and the cap is stored in the bezel 40 away from the bezel ceiling surface 40Up, and there is no risk of damaging the front surface of the cap. The anchor position can be clearly indicated by drawing a FIX anchor mark (pictogram).

  Further, the hinge pin 52 is held between the guide groove protrusion (stopper) 42 ′ and the rear end 42 Rr of the guide groove to prevent the movement in the front-rear direction, and the restriction pin 44 and the bezel ceiling surface 40 Up raise and lower the hinge pin 52.
